Title: Manufacture of semiconductor light-emitting device
Inventor: YAMAMOTO AKISUKE
IPC: H01S5/00
Filed: 1995-02-15
Abstract: PURPOSE: To obtain a manufacture of a semiconductor light-emitting device which can prevent a material of a current block layer from sticking on the surface of a mask for selective growth of the current block layer. CONSTITUTION: A stripe-shaped SiON film 10 of a thickness 50nm or less is formed on a P-type GaAs cap layer 5. With this film used as a mask, the cap layer 5 and an upper clad layer 4 are etched to a prescribed depth so as to form an optical waveguide, and an N-type GaAs current block layer 6 is made to grow selectively, with the SiON film used as the mask, in an etched-off part. After this mask is removed, a contact layer 7 is made to grow. Accordingly, a growth fault of the P-type GaAs contact layer can be suppressed, and since generation of a dark line due to a stress between the mask for the selective growth of the current block layer and the P-type GaAs cap layer is suppressed, lowering of a light output to be caused thereby can be prevented.

Title: Code reader
Inventor: OUCHI IKUO
IPC: G06K7/015
Filed: 1989-02-07
Abstract: PURPOSE:To prevent a user from being embarrassed unnecessarily by discharging and returning a recording medium promptly when an error occurs because the recording medium is inserted as being turned upside down. CONSTITUTION:When a decoder 2 can not decode an input bar code signal bc, it sends an error signal er to a first timer 5, a first switching device 8 and a counter 7. The time-up signal t1 of the timer 5 is given to a scanner 1 as a re-reading instruction, and the switching device 8 gives a normal rotation drive signal (m) to a motor 4, and makes it rotate. Thus, when a card is carried, and the counter 7 counts the portion of the number of times of bar code re- scanning set beforehand, it makes a second timer 6 start. Then, after the lapse of prescribed time, the motor 4 is stopped, and the card is discharged. When the read bar code can not be decoded, the read of the card is stopped promptly, and the card is returned, and the user is informed.

Title: Turbulence generator
Inventor: HONDA AKIHIRO
IPC: G01M9/00
Filed: 1994-02-24
Abstract: PURPOSE:To reproduce a greater wind turbulence by rocking, back and forth, a rocking plate in the direction crossing the flow of wind in addition to the rocking of the rocking plate. CONSTITUTION:Along with the rotation of a circular plate 9 for rocking back and forth using an elevator motor, an elevation plate 15 repeats up and down elevation and at the same time moves a rocking plate 1 up and down at a constant period (heaving vibration). Further. with the rotation of a circular plate 5 for rocking provided at a rocking motor. the rocking plate 1 is rocked (pitching rotation) around a rocking pin 7, thus applying up and down movement to the rocking plate 1 in addition to rocking and hence reproducing a greater wind turbulence. Also, by suppressing the speed of the circular plates 5 and 6, wind turbulence in a diversified pattern can be formed.

Title: Paper feeder
Inventor: IKUNAMI KEIICHI
IPC: B65H3/52
Filed: 1989-02-06
Abstract: PURPOSE:To change a surface position of a handling roller contacting with a feed belt as well as to eliminate a sheet of paper sandwiched between rollers by using a reversible turning motor for a motor driving the feed belt, and installing a one-way clutch in space between the handling roller and a fixed shaft. CONSTITUTION:A handling roller 4 is engaged with a fixed shaft 10 with some play, and each ratchet 11, whose tip is energized by a spring in its opening direction, installed in this fixed shaft is engaged with a ratchet internal gear 4a on an inner surface of the handling roller 4. When a surface contacting with a feed belt 3 of the handling roller 4 is changed, if a reversible turning motor 8 is reversed, the feed belt 3 is liable to rotate the handling roller 4 in reverse to the feeding direction. Since engagement between the ratchet 11 and the ratchet internal gear 4a cannot stop the reverse rotation against the feeding direction of the handling roller 4, this roller 4 rotates in reverse to the feeding direction. When rotation of the feed belt 3 is stopped in the state that paper is sandwiched between the feed belt 3 and the handling roller 4, reverse rotation is performed for a proper time so that the paper can be discharged to the side of a tray.

Title: Manufacture of semiconductor laser device
Inventor: YOSHIKAWA AKIO
IPC: H01S5/00
Filed: 1986-02-12
Abstract: PURPOSE:To prevent the annulment of an internal stripe structure, by forming a groove right above a current blocking layer of multi-layer structure formed on a substrate possessing a ridge, and forming a double hetero-structure in the blocking layer containing the groove. CONSTITUTION:A ridge is formed on a GaAs substrate 1, and a current blocking layer 10 is formed thereon by epitaxial growth, wherein a plurality of GaAs layers having a conduction type inverse to the substrate and barrier layers are alternately formed. Using a photo mask, a central portion of the ridge in the blocking layer 10 is eliminated in the form of a stripe, which is used as a mask for etching to expose a part of the substrate 1. After that, a double hetero-structure is grown on the substrate surface, followed by the formations of a clad layer 4, an active layer 5, a clad layer 6 and a cap layer 7. In this manner, the annulment of an internal stripe structure can be prevented, even if the thickness and the carrier density of the current blocking layer disperse irregularly. Consequently, a laser device which operates with a small current and oscillates in a fundamental mode can be manufactured with high reproducibility.

Title: Operation control system for work vehicle
Inventor: KUWAGAKI MASAHIRO
IPC: G05B9/02
Filed: 1996-01-23
Abstract: PROBLEM TO BE SOLVED: To prevent the wrong start of programs that are caused by the wrong input signals by adding a timer into a microcomputer unit to delay the start of a main program and a hard check program by a prescribed time after the initialization when the operating condition of the microcomputer unit is set. SOLUTION: A timer 44 secures a prescribed time interval before a hard check program or a main program is started after the power supply of a microcomputer unit 29 is turned on. These programs never start while the timer 44 is operating. The interval time of the timer 44 is set longer than a period when the power voltage is stabilized at a normal level after the power supply is turned on. Then no program is started during the operation of the timer 44 even when a hard check signal is inputted to a microcomputer unit 29 before the instantaneous voltage of an ON state of the power supply is coincident with the voltage level that is equivalent to the hard check input signal.

Title: Molding material for shell mold
Inventor: YATSUSE MASAYOSHI
IPC: B22C1/22
Filed: 1985-02-15
Abstract: PURPOSE:To prevent effectively the formation of a chilled part of iron casting, especially for an iron casting having a thin metal part, by using a molding material prepared by mixing an SiO2, having prescribed grain-size index and gas permeability, and a phenolic resin large in fire catching speed at a specific fashion point. CONSTITUTION:This molding material is prepared by mixing a 3-4% phenolic resin, having a 95-105 deg.C fusion point and a large fire-catching speed, with a major component SiO2 having a 60-90 grain-size index and 80-130 gas permeability. When a dumping-type shell mold is molded by the shell-mold send obtained in such manner, the gas permeability is properly lowered as well as the fire-catching speed of resin is enhanced, to improve the heat retentivity of the inside of shell mold. Also, the fluidity of molten metal is enhanced by the soot, etc. produced by the combustion of resin, to improve the run of molten metal. As a result, the solidifying speed by quenching of the molten metal can be delayed to prevent the formation of chilled part.
