Title: Heat treatment method
Inventor: KONO MICHIHISA
IPC: H01L21/318
Filed: 1990-07-10
Abstract: PURPOSE:To solve problems such as peeling off of a film and generation of cracks and to enable formation of an ion-implanted active layer of good uniformity and reproducibility by using a protection film which has an SiOxNy graded layer having composition to change from Si3N4 to SiO2 smoothly on an Si3N2 film and which is provided with an SiO2 layer deposited on an uppermost part thereof. CONSTITUTION:An SixNy graded layer 3 is on an Si3N4 film layer 2 formed on a GaAs substrate 1, and an SiO2 layer 4 is deposited on an uppermost part thereof. A film of such a structure is used as an annealing protection film and Si<+> of 1X10<13>cm<-2> is implanted to the semi-insulating GaAs substrate 1 at implantation energy of 100keV at a room temperature to form an ion implantation layer 5. Thereafter, an active layer sheet is acquired as a result of treatment for 10sec at 900 deg.C by using the annealing protection film. Dispersion in resistance of the acquired active layer sheet is greatly improved compared with dispersion when Si3N4 is used for a protection film. Furthermore, it is effective not only to ion implantation conditions but also to other implantation conditions. Thereby, uniformity in a plane of a substrate can be greatly improved.

Title: Printer
Inventor: KAMEI TOSHIHITO
IPC: B41J29/46
Filed: 1986-08-04
Abstract: PURPOSE:To reduce the necessary capacity of a memory, by constructing such that the content of an error is printed when printing can be performed under an erroneous condition and printing the content of the error when printing can be performed under an erroneous condition being produced. CONSTITUTION:When a CPU5 detects a parity error in printing data being transferred through RS232CI/F4, CPU5 sedns a voice code of 'serial error' to a voice only CPU11. On the basis of said voice code, the voice only CPU11 takes out voice data from a dictionary ROM12 and sends them to a voice generator 13. The voice generator 13 converts said voice data to a voice which is announced through a speaker 28. In case of a printable error such as a serial transfer error, only the occurrence of an error is announced with voice and the content of the error is alarmed through printing. Consequently, the capacity of memory can be reduced considerably when compared with the case where the error is alarmed entirely with voice.

Abstract: PURPOSE:To enable inter-multipoint optical amplification repeating by using a bidirectional light transmission system capable of easily making inter- multipoint communication by frequency (wavelength) assignment. CONSTITUTION:The light signal 2-1 from the point A is coupled to the light signal 2-2 from the point B by an optical coupler 2-3. This signal enters an optical amplifier 2-4, by which the signal is amplified. This signal is further bisected by a demultiplexer 2-9. One amplified signal 2-5 propagates to the point C. Another signal is coupled to the light signal 2-6 from the point C by an optical coupler 2-10. This signal enters an amplifier 2-7. The amplified signal 2-11 is branched by an optical demultiplexer 2-8 and is propagated to the point A and the point B. The assigned frequencies (or wavelengths) can be received without mixing at the respective points A, B, C by optical filters or light frequency tuning techniques. The communication between A and C, B and C and A and B is thereby executed.

Abstract: PURPOSE:To call passenger's attention to his mischief for restraining him surely from his mischief by providing a means for detecting the mischief such as rolling eaused by the passenger in a cage of an elevator while turning off the illumination in the cage at the detection of the mischief. CONSTITUTION:When a passenger does mischief to a cage to roll it during running of an elevator, the number of pulses from a rotary encoder interlocked with the cage is varied, so that a calculating controller detects and judges the mischief, closes a contact I and excites a relay K. Thus, the relay K holds itself by respective contacts M, Ka while illumination L is turned off by opening a contact Kb. When the cage thereafter reaches the closest story and stops, the contact M is opened to demagnetize the relay K, close a contact Kb and turn on the illumination L. Thus, the cage is temporarily kept dark to call the passenger's attention to his mischief for restraining surely him from miscief.

Title: Sheet feeder
Inventor: SASAKI NOBUKAZU
IPC: B65H1/12
Filed: 1982-10-18
Abstract: PURPOSE:To relieve a shock produced when a sheet feed roller makes contact with a sheet and to stabilize the supply of sheets by means of the sheet feed roller, by installing a cushioning member in a drive system located between a clutching member, controlling the supply of the sheets, and the sheet feed roller. CONSTITUTION:When an electromagnetic solenoid 35 receives a sheet feed signal, an arm 36 is moved to position shown by a dotted line to actuate a control ring 37 and a spring clutch 38, and thereby, a sheet feed shaft 12 starts to turn through the working of a follower roller 33, a cushioning member 40, and a boss 39. In which case, since the load of the sheet feed shaft 12 is only friction loads between the shaft and a bearing 20 and the sheet feed roller 13, the loads are low, and a rubber, serving as the cushioning member 40, is almost freed from deformation. When the sheet feed shaft 12 is further turned and an end 1b of a sheet feed roller 11 makes contact with a transfer material 17, a load, which pushes the transfer materials 17 against the end part through the elastic force opf a retainer spring 18, is suddenly applied on said end 11b, but the cushioning member 40 is bent to damp the load. This allows reduction of an impact applied on the transfer sheet 17, and enables the transfer sheets 17 to more properly follow the sheet feed roller 11.
