摘要:
A slide guide device for a press guides a slide in a cycle. The slide guide device eliminates eccentric force misalignment and prevents eccentric contact between the slide and a gib. The slide includes at least a first spherical shoe having at least a first guide surface. The gib includes at least a first sliding surface opposite the first guide surface. During operation, the spherical shoe rotates relative to the slide to provide automatic planar alignment between the first guide surface and the sliding surface. A wedge supports the gib to allow rapid and easy alignment with the slide.

A lateral high-breakdown-voltage transistor comprises an n− drain region and an n+ source region formed in a p− silicon substrate, separated from each other, a gate electrode formed on a channel, insulated from the substrate, an n+ drain contact region formed in the drain region, drain wiring electrically connected to the drain region via the drain contact region, a p+ substrate contact region formed in contact with the source region, and source wiring electrically connected to the source region and also connected to the semiconductor layer via the substrate contact region. The transistor is characterized in that the substrate contact regions have respective portions made to be in contact with the source wiring, and accordingly laterally extend from inside the contact surface of the source wiring to outside the contact surface.

Disclosed is a low-profile card connector comprising a U-shaped housing; terminals mounted in the housing; and a card ejector comprising a rotary lever and an ejection rod for turning the rotary lever. The rotary lever comprises front and rear sections. The front section is contiguous with the rear section, and is in a plane lower and parallel to the rear section. The front section is rotatably fixed to the main body, and is covered by a cover member, which is assembled to the main body and the overlying front section of the rotary lever to be coplanar with the rear section of the rotary lever.

A middle liner of a slide guide device for a machine press has a spherical shaped side which fits into a sliding gib attached to a slide. The middle liner slides along a fixed gib at first and second linear surfaces that are at an angle with each other. The combination of self-alignment and smooth movement of the slide is achieved in the presence of an eccentric load acting on the slide. A machine press equipped with such a slide guide device has excellent eccentric load resistance and high working precision. In a further embodiment, a press machine is further equipped with a knockout device having knockout block moving between a pair of guide rails. A plurality of middle liners, each having at least one spherical surface, are positioned between the knockout block and the guide rails. The resulting knockout device provides a stable knockout load with low noise and low energy consumption.

An improved wireless remote controller for controlling each of several devices under control in each mode of operation without requiring any switching among devices under control and thus having no device switching key mounted thereon. The wireless remote controller has a plurality of operation selection keys and is designed to operate in such manner that when the controller is directed toward one of the devices under control and any one of the operation mode selection keys is depressed, a corresponding operation mode signal is generated and transmitted to a device under control. The operation mode signal includes a series of consecutive signal components for operating all the devices under control. The device under control responds only to the associated one of the signal components of the operation mode signal.
摘要:
A method of manufacturing a semiconductor apparatus is disclosed, in which in the method of isolating elements, is improved. A groove is cut in a semiconductor substrate. Elements are isolated from each other by embedding an insulating material in the groove, in two divided portions. The time required for depositing an insulating material is reduced, thereby forming a uniform insulation layer on the semiconductor substrate. Since the insulating material can be etched in a shorter period of time than was previously required, the etching process can be more finely controlled. Since a field oxide layer is formed by oxidizing an insulation layer formed for the first time, the field oxide layer can be provided without oxidizing those portions of the semiconductor substrate which lie near the groove. Consequently, the seminconductor substrate can be free from crystalline defects.
