Title: Optical head
Inventor: ANDOU HIDEO
IPC: G11B7/09
Filed: 1981-09-17
Abstract: PURPOSE:To ensure the stable detection for both a shifted tracking and the out- of-focus, by branching the light beam reflected from an information forming layer and passed through an objective lens into two parts to be led to a 2-split photodetector after extracting the direct light and the light asymmetrical to the optical axis and then detecting the difference output between the photodetecting cells. CONSTITUTION:The laser light 11 is condensed on an information forming layer 4 via a coupling lens 13, a polarized beam splitter 15, a lambda/4 plate 16 and an objective lens 17. The reflected light travels backward to pass through the splitter 15 and is reflected by a half mirror 27 to be formed into an image on a 2-split photodetector 28 as well as on a 2-split photodetector 26 after passing through the mirror 27 and via a light shielding plate 23 set at the position out of the optical axis and a lens 24. Then the out-of-focus is detected from the difference output between photodetecting cells 26a and 26b; while a track shift is detected from the difference output between photodetecting cells 28a and 28b respectively.

Title: Semiconductor device and manufacture thereof
Inventor: MOTODA TAKASHI
IPC: H01S5/00
Filed: 1995-06-14
Abstract: PURPOSE: To provide the manufacturing method of a semiconductor device on which a light modulator, having an excellent extinction ratio, and a laser element are integrated on the same board. CONSTITUTION: A semiconductor layer, containing an InGaAsP multiple quantum well active layer 3, is grown by a MOCVD method on the surface of an N-type InP board 1 having a microscopic rugged surface 111 on a part of the backside and a mirror face on the other side. At this time, the radiation of heat coming from a susceptor 12, which is heated by a heater 13, is reflected on the rugged surface of the backside of the board, but as the heat is absorbed by the board on the mirror face region, the temperature of the mirror face region becomes higher, and the composition of InGaAsP on the two regions is differentiated. Accordingly, as the surface of the semiconductor layer is flattened, a laser element can be stably formed on the rugged surface region, and a light modulator can be stably formed on the mirror face region.  Also, as the precise InGAAsP composition can be controlled, the extinction ratio of the light modulator can be improved.

Filed: 1980-10-23
Abstract: PURPOSE: To obtain a floppy disc driver having a door opening mechanism by making the signal for door releasing by utilizing the signal for locking the door of a controller adequately.  
     CONSTITUTION: First, a door is opened and a floppy disc is set in a driver 2. Thereafter, the door is reclosed. The signal for door locking is enabled and is fed from a controller 1. Then, this signal is applied to a driver 10, and from the driver 10, electric current flows to a transistor 5 and the TR5 goes on. As a result, a solenoid 6 for door locking is energized to lock the door. If the need for opening the door arises after this, the signal for door locking is disabled and transmitted from the controller 1. Thereby, the signal logically inverted from that at the door locking is inputted to a driver 7. Hence, electric current is supplied to a transistor 8, and the TR8 goes on. A solenoid 9 for door releasing is energized to open the door.

Abstract: PURPOSE:To reduce the generation of a bird's beak and thereby enhance device integration by a method wherein polycrystalline Si occupying a V-shaped groove is subjected to a highly concentrated doping impurity for a selective oxidation at low temperature. CONSTITUTION:A polycrystalline Si 5 is formed to occupy a V-shaped groove and a high concentration of such dopant as B, P, or As is put into the surface of the polycrystalline Si 5 (5' indicating the doped portion). Either diffusion or ion implantation may be used as a doping technique but, where the ion implantation method is employed, a dosage of 5X10<15>-5X10<16>cm<-2> and an accelerating voltage of 20-30KeV will be used. Polycrystalline Si thus treated is rapidly affected by selective heat oxidation at low temperatures 850-1,000 deg.C. An SiO2 film 20 thus formed is less in bird's beak size L2 on account of a shortened selective heat-oxidation period as compared with the conventional method. Accordingly, a semiconductor element forming region is realized larger than expected in a conventional method.

Abstract: PURPOSE:To prevent waste of a resin and to dispense with aftertreatment by measuring variations of pressure in blowing a resin flow into a supply pipe, and detecting the arrival of the lining resin at a duct. CONSTITUTION:A lining resin is blown as a fog into a supply pipe 2 by the operation of a blower 6, deposited on the inner wall of the pipe 2 to form a lining layer, and sent to the duct 1 side. In said process, the internal pressure of the pipe 2 is gradually increased by the injection of the lining resin. When the resin flow in the supply pipe 2 arrives at the junction of a duct 1, the leading part of the resin is spouted into the duct 1, and air runs away into the duct 1. Consequently, the internal pressure of the supply pipe 2 is decreased. Accordingly, the time when the internal pressure peaks is detected by a pressure gauge 10 as the time when the necessary amt. of the resin is supplied. The injection of the resin is stopped, and only the blower 6 is operated for specified hours. Repairs are carried out without wasting the resin in this way.

Filed: 1979-11-12
Abstract: PURPOSE:To increase the value of storage capacity, augment reading voltage and obtain an MOSRAM resisting noises by a method wherein a junction area of an N layer or an inversion layer and a semiconductor substrate is increased. CONSTITUTION:An N type buried layer 7' is also formed on a P epitaxial layer 1b on a P type substrate 1a with an N type buried layer 12, and connected by an N layer 11. The layers 12, 7' each have corrugated uneven sections on junction surfaces with the layers 1a, 1b, and the layer 7' is a charge accumulation layer or an inversion layer. Storage capacity is made up by the MOS capacity of the poly Si3 of the first layer and the N layer 7' and junction capacity between the layer 7' and the layer 1b, between the layer 11 and the layer 1b, between the layer 12 and the layer 1b and between the layer 12 and the substrate 1a. Reading voltage is increased because a junction area of the N type inversion layer 7' and the N type buried layer 12 is wide and junction capacity is large. According to this constitution, the concentration of the substrate 1a can be augmented independently of the threshold voltage of an MOSFET and the capacity of a bit wire, and storage capacity can be increased.
