Patent JP-S6370474-A (JP)
Title: Manufacture of semiconductor laser element
Inventor: FURUYAMA HIDETO
IPC: H01S5/042
Filed: 1986-09-12
Abstract: PURPOSE:To make high frequency characteristics excellent, by determining the width of an active region by the deformed growing of the active layer on a stripe mesa, which is provided on a semiconductor substrate, and removing the active 1 layer other then the active region. CONSTITUTION:A stripe mesa having a specified width is formed on an N-type (100) InP substrate 1. Then, as crystal growth, N-InP buffer layer 2, a non-doped GaInAsP active layer 3, a P-InP clad layer 4 and a P<+> GaInAsP cap layer 5 are sequentially grown by a liquid growth method. The thicknesses of the active layer 3 at this time are different at the upper part of the mesa and at a flat part. At the flat part, the thickness becomes 3-4 times that of the upper part of the mesa. The layer becomes thin on both sides of the mesa. Then, an SiO2 CVD film as an etching mask 10 is provided. Mesa etching of the cap layer 5 and the P-InP clad layer 4 is performed. The etching of the cap layer 5 is performed until the surface of the P-InP 4 is reached. Thereafter, the active layer 3 on the mesa, i.e., the active layer 3 other than the active region, is removed. Thus, the controllability of the width of the active layer, floating capacitance and the like are improved.

Title: Heating device for vehicle
Inventor: OKADA MASAKI
IPC: B60H1/18
Filed: 1986-09-12
Abstract: PURPOSE:To prevent the back flow of a combustion gas from an engine by switching over a combustion gas generated by a heater to either of a combustion gas passage for discharging it into the intake pipe of an engine or a combustion gas passage for discharging it out to the open air, in accordance with the opening and closing of an exhaust brake. CONSTITUTION:A combustion gas obtained by a combustor 5 is fed into a heat exchanger 8 and subjected to heat exchange, and, then, fed into the intake pipe 3 of an engine 1 or a combustion gas passage 18 which is opened to the open air, through a combustion gas passage 16. When both of the engine 1 and the heater are operating and as the combustion gas generated by the combustor 5 of a heater is to be taken into the engine 1, a selector valve 25 is switched over to an open side with respect to the intake pipe 3. When an exhaust brake is operated, the selector valve 25 is switched over to connect the combustion gas passage 16 on the lower course side of the heat exchanger 8 to a combustion gas passage 18 which is opened to the open air. Thereby, the back flow of the combustion gas from the engine 1 can be prevented..

Title: Data transfer system
Inventor: OTANI MASAYUKI
IPC: G03G15/04
Filed: 1986-09-12
Abstract: PURPOSE:To send data at a high speed to an eraser with a small number signal lines and to improve reliability and accuracy by switching to I/O interface mode only at the time of transmission of data to the eraser by a serial asynchronous system. CONSTITUTION:When data addressed to a block B is sent from a TXD in the serial asynchronous system from a control block B relating to sequence and operation, the block B uses a serial data input terminal PC1 of a microcomputer 31 to receive the data. When the reception is finished, the data is sent from a serial data output terminal PC0, the block A uses the PC1 to receive it. After the reception of data of the block A from the block B, in the timing of data transmission to the eraser, the mode is switched to the I/O interface mode and the data is sent by 8 bytes to the eraser control block C. The mode is switched again into the asynchronous mode after the end and the data to the block B is sent. Thus, the data transmission to the eraser is attained at a high speed with a small number of signal lines and the reliability and accuracy are improved.

Title: Control circuit for kerosene burner
Inventor: MORITO KATSUMI
IPC: F23N5/24
Filed: 1986-09-11
Abstract: PURPOSE:To stop combustion of a burner before critical condition occurs, when the rate of heat back by combustion flames is decreased due to shortage of oxygen during combustion, by constituting a control circuit of a temperature detector for a combustion body, two comparators, a timer, a NOR circuit, and a relay control circuit. CONSTITUTION:A comparator 23 inverts an output when the temperature in a burner body 3 detected by a thermister 17 reaches a primary predetermined temperature, and it inverts an output again when the temperature reaches a secondary predetermined temperature which is lower than the primary one. A comparator 28 inverts an output when the temperature in the burner body 3 reaches a tertiary predetermined temperature which is between the primary and the secondary predetermined temperatures, and it inverts an output again when the temperature reaches the fourth predetermined temperature which is lower than the tertiary one. Utilizing those inverting actions to outputs, a timer 34 outputs a time-up signal when a predetermined time elapsed after the temperature had reached the tertiary predetermined temperature. A NOR circuit 32 stops supplying of electric power to an evaporating heater 16 by a time-up signal, or when the temperature reaches the primary predetermined temperature. A relay control circuit 39 starts combustion when the temperature reaches the tertiary predetermined temperature, and it stops combustion when the temperature reaches the fourth predetermined temperature.

Title: Method and apparatus for measuring toner charge distribution
Inventor: HAYASHI SHUJI
IPC: G01R29/24
Filed: 1984-10-12
Abstract: PURPOSE:To prevent variations in the printing density, by measuring the passage of a measuring light attracting and holding charged toner above a space through which the measuring light passes by an electrostatic power to determine the magnitude and distribution of the charge of toner. CONSTITUTION:After charged with a corona charger 4, a photosensitive drum 3 turns to attract and hold toner T. Light from a light source 9 is divided with a splitter 10 and a measuring light 11 is detected with a measuring light receiver 14 passing through a clearance 7 right under the drum 3 while a reference light 12 is detected with a reference light receiver 15 passing through a space clear of an obstacle. The intensities of the lights detected with the light receivers 14 and 15 are compared with a detection circuit 16 and the resulting difference is outputted to a measuring circuit 19. Then, as an electrostatic power reduction means 17 is adjusted with a charge controller 18 to reduce the intensity of electrostatic power sequentially, toner drops starting from the least amount of charge thereof. Since the toner intercepts the measuring light 11 temporarily as dropping through the clearance 7 through which the measuring light 11 passes, the distribution of the quantity of toner is obtained with respect to the amount of charge thereof by taking correlation between the intensity of electrostatic power and changes in the intensity of the measuring light.
