Title: Semiconductor device
Inventor: SUKEGAWA SHUNICHI
IPC: H01L29/72
Filed: 1988-03-14
Abstract: PURPOSE:To make possible the high-speed operation of a semiconductor device by a method wherein a semiconductor layer is buried in the lower part of a hole (a trench groove or the like) formed on the side of one main surface of a semiconductor substrate and a high-temperature treatment is eliminated in such a way that the lower electrode of a vertical type semiconductor element on the side of the hole is led out through a diffused region diffused from this semiconductor layer. CONSTITUTION:An N-type well diffused region 22 is formed on the side of one main surface of a P-type Si substrate 21, an N<+> poly Si layer 30 containing an N-type impurity in a high concentration is buried in the lower part of a trench groove 20 formed in this well region and an N<+> collector region 27 is formed integrally with the layer 30 on the side of the layer 30 by the self-diffusion of an impurity from the layer 30. An N+ poly Si collector electrode 38 insulated from its periphery with an Si oxide film 35 is adhered at a position right over the layer 30. Accordingly, a high-temperature thermal process is not needed for the formation of the region 27 not it is needed to grow an epitaxial layer. Moreover, the parasitic capacity of the region 27 is reduced and as the electrode 38 reaches up to the same depth as that of the region 27, the parasitic resistance of the region 27 is also small. Thereby, the high-speed operation of a semiconductor device becomes possible.

Abstract: PURPOSE:To adjust a distance over a wide range by laterally moving objective lenses on a movable side and prisms for changing the optical axes of the objective lenses in parallel to an optical scale and making a magnification invariable even when distances between the objective lenses are adjusted. CONSTITUTION:Both ends of an object to be measured on an optical scale 1 are caught by right and left objective lenses 5 and 3 and right and left images 28' and 28 are united in the same field of view via right and left polarizing prisms 7 and 6, right and left objective lenses 14 and 12, respectively, and a right and left optical image coincident prism unit 15, being observed. The visually estimated lengths of the object to be measured are made to coincide with each other on the standard scale 1 by moving the lenses 5 and 3 in advance, then the object to be measured is located on the scale 1 and both the images of a measuring point are made to coincide with reference lines 29' and 29 in the field of view. Thus, when the images are coincident with the reference lines 29' and 29, an actual length is the same as a dimension read from the scale 1. When not coincident, the lenses 4 and 3 are moved by a micrometer 11 or 10 to be made coincide with the reference lines and addition and subtraction operations are conducted on the moving quantities of the lenses 4 and 3 whereby the actual length is read.

Filed: 1995-03-20
Abstract: PURPOSE: To stably carry an accumulated article by making an article carrying member, which moves vertically upward passing through an opening in a mounting table, lift up the article that is brought onto the mounting table as the article is mounted on the carrying member between falling preventing members. CONSTITUTION: An article carrying member 20 moves almost vertically form the lower part toward the upper part through an opening 42 made in a mounting table 30. The article is pushed by a pusher onto the mounting table 30 at a period synchronous with the period in which the article carrying member passes the opening 42, and the pusher is engaged with an article stopping member 44 so that the article is mounted on the mounting table 30 at the prescribed position. The article mounted on the mounting table 30 is picked up by a pick-up member 34 of the article carrying member 20 to be transferred to the interior part of an article accumulating device.  At this time, the article is transferred while the article is held from both sides by article- falling-preventing members 36, which are formed at both ends of the pick-up member 34 in such a manner that the members 36 stretch themselves upward in the almost vertical direction. Accordingly, the accumulated articles are prevented from slipping off from the article carrying member 20, and consequently they can be transferred in a stable manner.

Title: Laser light emitting device and disk reproducing device
Inventor: NAKANE HIROSHI
IPC: G11B19/04
Filed: 1999-03-08
Abstract: PROBLEM TO BE SOLVED: To provide a laser light emitting device, which can be improved in reliability by preventing a semiconductor laser from being damaged by an excessively large current due to imperfect contact of a connector and a disk reproducing device using the device. SOLUTION: A capacitor C1, which is a constituent of a time constant circuit, is connected to an APC loop composed of a connector CN and a laser diode LD. When the connector CN is conducted from a non-conducting state, currents are supplied to the diode LD and capacitor C1 through a resistor R2. When the currents are supplied, the output of the diode LD does not exceed the maximum rated value, and the diode LD is not damaged, because the both-terminal voltage of the diode LD rises with a time constant of the resistor R2 and capacitor C1.

Abstract: PURPOSE:To permit quick change-over of automatic and manual driving of a moving optical system and to improve operability by detecting the moving end of the moving optical system and braking the electrical driving for the movement. CONSTITUTION:A planetary gear 41 revolves when a rotating cylinder 19 is turned by executing manual focusing during automatic focusing by the electrical driving. The rotation of an electrically driven internal gear 17 and the revolution of a gear 41 are then synthesized in a differential gear system and a cam cylinder 13 turns in response therewith, thus moving lenses L1, L2. The turning angle of the cam cylinder 13 is detected by an encoder 55. A driving motor is braked and the revolution of the gear 41 is surely stopped by a CPU 29 when the detection signal of the moving end of the moving optical system in the infinite and close distance states is supplied to the CPU. The moving end of the moving optical system is thus known and the inadvertent rotation of a manual operating ring is prevented. The free change-over of the automatic driving and manual driving of the moving optical system is thus permitted without troubles and the operability is improved.
