Title: Method for homogenizing gallium arsenide single crystal
Inventor: SATO MASAZUMI
IPC: C30B29/42
Filed: 1987-05-28
Abstract: PURPOSE:To homogenize a gallium arsenide single crystal and readily obtain the electrically homogeneous single crystal, by previously heat-treating a gallium arsenide single crystal grown by a liquid encapsulated Czochralski (LEC) method at a relatively low temperature and carrying out ingot.annealing at a specific temperature. CONSTITUTION:A gallium arsenide single crystal grown by the LEC method is previously heat-treated at a relatively low temperature of 200-600 deg.C for about 5-20hr. Defects in an unstable state in electrically active defects present in the grown gallium arsenide single crystal are converted into a state without disappearing even at 800-900 deg.C temperature. Ingot.annealing is then carried out at 800-900 deg.C temperature to contrive stabilization of such defects, attain uniform defect distribution and homogenize the gallium arsenide single crystal. An electronic device having excellent characteristics with stabilized properties can be realized by using this single crystal.

IPC: G03D3/13
Filed: 1981-08-25
Abstract: PURPOSE:To prevent uneven development, by passing a photosensitive material downward and then upward through a developing soln. agitated countercurrently against the photosensitive film in both cases. CONSTITUTION:A photosensitive material is passed in the arrow direction along a cource shown by an alternate long and short dash line through conveying rollers 10, and guiding members 11-13.

Title: Original leaving warning device of copying machine
Inventor: YAMAMOTO YASUHIRO
IPC: G03G21/00
Filed: 1983-07-22
Abstract: PURPOSE:To prevent securely an original from being left by turning on a warning switch for the leaving of an original unless a control switch on a console panel is operated for a specific time set in a timer. CONSTITUTION:If a copy sheet 8 is removed before the original on copying operation, a warning means 22 does not operate by removing the original 4 within the set time T of the timer 19. When, however, the copy sheet 8 is taken out of a paper discharge tray 9 after the copying operation and the original 4 is left on contact glass 3 for the set time T of the timer T, an FF21 outputs an alarm signal AL to put the warning means 22, thereby giving a warning by warning display or a buzzer, etc. Consequently, an operator notices that the original 4 is left and takes out the original, and then a signal OD from an original detector 6 goes down to L to reset the FF21; and the warning means 22 stops operating, so the original is prevented from being left.

Filed: 1987-05-29
Abstract: PURPOSE:To logically obtain an area protection having various comprehensive relations by constituting a key of plural bits, and also, designating a different protection classification by a value '0' of each bit thereof. CONSTITUTION:A storage key A read out of a key storage device 11, based on an address of an access request is inputted to an area protection control circuit 14 together with a program key B of a program status word (PSW) 13. The area protection control circuit 14 allows each hit (for instance, it is assumed to be 4 bits) of the storage key A and the program key B to correspond to each other, permits an access to a main storage device 12 in the case of A+B=A, and inhibits an access in the case of A+Bnot equal to A. Accordingly, since the key of plural bits is used, a program having an access request to the main storage can have the right of an access by designating plural arbitrary areas having different protection classifications. In such a way, various main storage protections can be realized.
