Title: Laser diode driver
Inventor: OMURA MASANOBU
IPC: B41J2/44
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To stabilize a current in the vicinity of oscillation threshold level by feeding the cathode of a laser diode with a current obtained by superposing a pulse current and a bias current using a laser diode drive current and a current control means. SOLUTION: An oscillation threshold current I2 is determined from the difference between a laser diode drive current Idrv controlled such that a laser diode 1 emits a desired quantity of light and a current required for obtaining 1/n of the desired quantity of light. The current 12 is then added to a constant current 1x to obtain a limit current value I0. A current limit circuit 7 limits the drive current Idrv to the limit current value I0 to produce an output current L1 providing an amplitude level at the time of pulse modulation. A pulse current IP for controlling light emitting operation is determined from the output current L1 and subtracted from the drive current Idrv to obtain a bias current IB which is superposed on the current IP and fed to the cathode of the laser diode 1.

Title: Formation of gate insulating film
Inventor: ISHIKAWA MICHIO
IPC: H01L21/316
Filed: 1991-03-13
Abstract: PURPOSE:To form the gate insulating film of an oxide at a low temperature and by a sputtering method by reducing the damage caused by plasma. CONSTITUTION:When the thin-film gate insulating film of an oxide is formed by a sputtering method, a parallel magnetic field on the surface of a target is held at 500 gauss or higher and a sputtering operation is executed. The energy of negative ions which break into a substrate during the sputtering operation is lowered, and the damage to the interface between the substrate and the gate insulating film and to the gate insulating film is reduced. As a result, it is possible to obtain the excellent gate insulating film whose interface level density and fixed charge density are small, and a low-cost glass substrate can be used because the temperature of the substrate during the film formation operation is low.

Title: Hot air flow space heater
Inventor: HARA SHOICHI
IPC: F24H3/04
Filed: 1985-03-12
Abstract: PURPOSE:To prevent the combustion condition of the space heater from being changed even when a lower angle of a louver varies by controlling the rotational speed of a fan in linkage with the variation in the lower angle of a variable louver provided at a hot air flow blow-off port. CONSTITUTION:Fan control means 10 such as a variable resistor or the like controlling the rotational speed of a fan 5 operates in linkage with the variation in the louver angle of a louver 8. That is, the fan control means 10 is connected in series to a fan motor 11 so as to increase the rotational speed of the fan 5 in accordance with the increase in the louver angle and the resistance of a hot air flow blow-off port 6. When the louver angle is small, the resistance of the air flow blow-off port 6 is normal, and hence the rotational speed of the fan 5 is also normal. Thus, the quantity of air optimum for the combustion of a burner 3 flows thereinto. When the angle of the louver 8 is made larger, and the rotational speed of the fan 5 is varied greatly (when the louver angle is made larger, the variable resistance value becomes small, and the rotational speed increases), and the air-fuel ratio of the burner and the flame current value are constantly held at predetermined values.

Filed: 1992-03-06
Abstract: PURPOSE:To enable even an unexperienced person to determine the priority order of event selection by easy calculation by digitizing the influence of an event upon a vehicle and determining a priority order table of events according to the obtained numericals. CONSTITUTION:The influence of the event on a travel of one vehicle is calculated as the delay Ta of the travel time. The rate (shunt rate) of vehicles where a broadcast is listened to travel in respective sections A-I is found from 'total number of vehicles in the respective sections divided by  total number of up and down travel vehicles at the broadcasting point'. In this case, the shunt rate alpha can previously be found as an accurate numeral by investigating the courses of traveling vehicles and prepared as a table. The calculated delay of the travel time is multiplied by the shunt rate to calculate the total delay time as the delay time of all the travel vehicles, which are rearranged in the decreasing order of the values, i.e., the influence upon the traveling vehicles to objectively generate an event selection priority order table according to the numerals.

Abstract: PROBLEM TO BE SOLVED: To provide a small-sized lightwelght vinyl sealer requiring no cord, short in standby time and capable of simply used for household or craft use. SOLUTION: A heating element 5 itself is directly brought into contact with a vinyl product 20 being an article to be fused. At this time, when the cross section of the heating element 5 is circular like a usual electric heating wire material, the contact area with the article to be fused becomes small and sufficient fusion is not performed and, therefore, the heating element is processed so that a flat part or a round pipe inner wall-like groove is formed on the surface of the heating element. Further, in order to obtain the sufficient mutual contact of vinyl products 10, 20 and the vinyl product 20 and the heating element 5, an instrument is formed into a hinge shape having an arm and the leading end part to which the heating element 5 is bonded is formed into a meshing shape and the vinyl products 10, 20 are grasped at the leading end part.
