Title: Error detecting device on optical head
Inventor: TAKEDA TADASHI
IPC: G11B7/135
Filed: 1991-11-29
Abstract: PURPOSE:To detect an error of an optical head without being influenced by fluctuations of a light source in wavelength by supplementing either of a focus error detecting signal and a track error signal based on a signal of a wavelength fluctuating component detecting means. CONSTITUTION:The device comprises four divided photodetector parts 9a-9d and bisective photodetector parts 9e and 9f in the same manner as conventional. A concentric circular fringe pattern is provided on a zone plate 30, where 1st-order diffracted light is so diffracted as to be converged into a spot outside a wavelength fluctuation detecting surface. A light beam transmitted as 0th-order light through the plate 30 out of the 1st-order diffracted light of a four-divided Fresnel zone plate 20 is led to the detecting parts 9a-9d of the four-divided detector, and the 1st-order diffracted light, diffracted out of the 0th-order light of the zone plate 20 by the plate 30 is led to the two divided detecting parts 9e and 9f for detecting wavelength fluctuations. A dividing line of the detecting parts 9e and 9f is orthogonal to the direction of tracks. Outputs A-D of the detecting parts 9a-9e are processed by an adder 11 and a subtractor 12 to obtain focus error signals F and T. Since the dividing line of the detectors 9e and 9f is orthogonal to the track, a wavelength fluctuation detecting output W is obtained without being influenced by a track error.

Title: Projection aligner
Inventor: MITO HIDEAKI
IPC: G03F7/20
Filed: 1990-11-30
Abstract: PURPOSE:To optimize the performance and yield of a semiconductor device at a low cost by changing the projecting magnification of a pattern formed on a photomask to a wafer. CONSTITUTION:Light emitted from a light source 11 advances along an optical path A after the light is condensed by means of elliptic mirrors 12 and the ultraviolet component of the light is reflected by means of a cold mirror 13 and its flux distributing characteristic is uniformized by a fly's-eye lens 14. Then the light irradiates a pattern 31 for confirming projecting magnification on a reticle 30 through a reflecting mirror 15 and condenser lens 16. A magnification detector 33 finds the projecting magnification of a projection lens 32 by detecting the projecting magnification of the pattern 31 and sends the found value to a magnification controller 34. The magnification of the lens 32 is changed until a desired magnification is obtained.

Abstract: PURPOSE:To make it possible to take a drastic turn which can not be created with a thrust direction control device by fixedly installing a rotary floating body which gives chip-off by sliding on the inner surface on the end of a cylindrical body in contact with the outside surface of a flying object which takes off. CONSTITUTION:When launching an airframe F, an actuator 4 is driven and a cylindrical body 2 is rotated by way of a pinion gear 5 and an outer gear 3 so as to tilt the airframe F at an target direction, thereby positioning a follower 6 at a specified position. Then, when the airframe F is launched from a launching cylinder 1, a follower 6 comes slidingly into contact with the outside surface of the airframe F so that a skirt S of the airframe F may come into contact with the follower 6, thereby forcibly tilting the posture of the flying object F at the target direction and gived a chip-off. This construction makes it possible to embody drastic turning and reach the target by tracing the route of the airframe at a low altitude.

Abstract: PURPOSE:To obtain a stress-free single crystal substrate in a high yield by annealing an InP ingot or an InP wafer at the melting point higher than the prescribed value or lower. CONSTITUTION:An S-doped InP single crystal ingot, which is formed by a LEC method, is melt-sealed together with red phosphorus in a vacuum quarts ampul of 1X10<-5>Torr.

The melt-sealed ampul is set in a soaking pit, and it is annealed at 1000 deg.C for twenty hours. After the annealing operation has been conducted at the programing rate of 100 deg.C/hr and at the cooling rate of 50 deg.C/hr, the circumference of the ampul is ground, sliced and finally, a double side mirror-polished wafer of 350mum in thickness is formed. As a result, the stress generated while crystal is grown can be removed, and stress-free InP single crystal can be manufactured in a high yield.

Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To eliminate unfavorable use of sodium azide because sodium azide is toxic and substance generated by its gasification exhibits strong toxicity, and inconvenience of a gas taking-out method, in which a sealing plate of a cartridge is broken with a needle by human power, to an operator having little power. SOLUTION: Properties of a gas generating agent 2 are instantaneously changed inside a container 11, and then, gas is made to be generated. Both of the generated gas and suction outside air under vacuum generated in the container 11 immediately after the gasification of the gas generating agent 2 are supplied to a body to be pressurized. In this case, there may be used a method for removing harmful components contained in the generated gas. Otherwise, there may be used a method for confining the gas generating agent 2 inside a permeable enveloped space so as to remove such harmful components when the components are leaked from the space in the form of gas. In the case of an insufficient supplying gas quantity, sealing of inflammable pressurized gas is instantaneously released by a pressure of the generated gas, so that the gas is supplied.  Respective apparatus are prepared for implementing these methods.
