Title: Vehicle light
Inventor: GOTO TAKAYOSHI
IPC: F21V5/00
Filed: 1998-04-02
Abstract: PROBLEM TO BE SOLVED: To provide a vehicle light wherein diffusion steps resisting the adhesion of mud and dust and allowing easily wiping off dust and mud with a dustcloth or the like are formed on the outer surface of a blow molded lens part. SOLUTION: A lamp comprises a hollow body-and-lens unit 11 in which a lamp body and a front lens which define a lamp room are integrally formed by blow molding, a light source 30 provided within the body-and-lens unit 11, and diffusion steps provided on the outer surface of the lens part of the body- and-lens unit 11, such as cylindrical steps 40 whose step elements have a certain directivity. Since the diffusion steps 40 on the outer surface of the lens part are given directivity by aligning the step elements 42 in a certain direction, the step elements 42 resist the adhesion of mud and dirt. The mud and dust clinging thereto can easily be wiped off with a dustcloth or washed off by waterflow in the direction in which the steps are directed.

Abstract: PURPOSE: To produce the subject compd. useful as an acylating agent in high purity from a carboxylic acid and inorg. acid halide by using a Mg halide or Mg in a form capable of being halogenated or a metal similar to Mg as a catalyst.  
     CONSTITUTION: A carboxylic acid (e.g.; p-acetoxybenzoic acid) and an inorg. acid halide (e.g.; phosgene) represented by the formula (wherein A is C or S and X is Cl or Br) are reacted by using a magnesium halide, a halide of a metal similar to magnesium (e.g. lithium, scandium) or a component becoming the magnesium halide or the halide of the metal similar to magnesium during reaction (e.g.; oxides or sulfates of these metals) as a catalyst to obtain a carboxylic acid halide (e.g.; p-acetoxybenzoyl chloride). The catalyst can be used again. A reaction by-product is little and a reaction accelerator is also unnecessary.

Title: Pilot operating type reducing valve
Inventor: MITO AKIO
IPC: G05D16/10
Filed: 1979-07-16
Abstract: PURPOSE: To prevent pressure of the circuit following the flow outlet from rising, by moving upward the main piston and making throttle response of the variable throttle valve slow for increment of the flow rate and by opening the movable throttle valve and making response quick for reduction of the flow rate.  
     CONSTITUTION: Variable throttle valve 40 which controls the throttle opening according to the passage flow rate of pilot relief valve 32 and has spool 35 pressed by spring 33 is provided for pressure of flow inlet 24. When pressure of flow outlet 24 rises and main piston 22 moves upward due to increment of the flow rate flowed to relief valve 32, variable throttle valve 40 is throttled to make response slow. Meanwhile, when the flow rate flowed to relief valve 32 is reduced or stopped and main piston 22 moves downward, throttle valve 40 is opened to make response quick. As a result, pressure of the circuit following the flow outlet can be prevented from rising by adjusting response of the pilot operating type reducing valve oppositely to the flow rate.

Title: Starting method and device for induction motor
Inventor: SUZUKI TATATOMI
IPC: H02P1/26
Filed: 1980-07-02
Abstract: PURPOSE:To abruptly rise the speed of an induction motor at the starting time by applying an alternating current having relatively high voltage and frequency to the motor during a short time after the starting. CONSTITUTION:When switches 7a, 7b for instructing start are closed, the set voltage of a frequency setting unit 6 is applied to an acceleration or deceleration regulator 8, and the output voltage from the regulator becomes linearly from zero volt to increased voltage. When the switch 7b is, on the other hand, closed, a signal 28 is applied from a differentiating circuit 11 to an adding point 9. Since a high voltage is applied to a voltage regulator 4 and a voltage-to-frequency converter 5 by the output of the circuit 11 after starting in this manner, the voltage and frequency of the alternating current supplied to an induction motor 1 are enhanced, and the rise of the speed of the motor can be abrupt.

Title: Method of fabricating resin sealed type semiconductor device
Inventor: HANYA KIMIHIRO
IPC: H01L23/48
Filed: 1978-07-24
Abstract: PURPOSE:To provide a resin sealed device of high quality and high reliability by use of lead wires provided at their full surfaces with a solder film. CONSTITUTION:A solder film is formed on the entire surfaces of lead wires 1a through 3a. When the lead wire 1a is heated in N2 to melt the solder on the surfaces thereof and rubbed against the collector electrode of a pellet 6a, the collector electrode of Ti-Ni-Au structure is easily soldered on the lead wires. Then the emitter and base electrodes are connected 7 to lead wires 2a and 3a by heat press-fitting. As the solder on the lead wires, a silver-containing high melting point solder is used to prevent the movement of the pellet by the heat pressure fitting. Ultimately, the required parts of the lead wires are sealed with a resin. In this organization, a film of a precious metal layer is unrequired, and the cost for material is reduced. The pellet press fitting temperature can be lowered by more than 1000 deg.C as compared with that of the conventional method, and therefore no characteristic deterioration of the pellet is produced and the reliability of the device is improved.

Abstract: PURPOSE:To enable to always guarantee the operation by providing a temperature sensor in an equipment, supplying electric power to a semiconductor element when the detected temperature is the prescribed temperature or lower to raise the temperature, and controlling it to fall in an available temperature proving range. CONSTITUTION:When a main power source switch 1 is closed, electric power is supplied through a transformer 4 to a load 5. At this time the voltage supplied to the load is detected and inputted to a control circuit 6, which compares it with a reference voltage, thereby setting a transistor 7 to ON or OFF to supply a constant voltage to the load 5. The switch 1 becomes ON in standby state, but a sub switch 2 is OFF. Accordingly, no power is supplied to the load 5. When a temperature sensor 8 becomes the prescribed temperature, it becomes ON to produce an operation command to the control circuit 6. In this manner, the control circuit 6 starts to drive the transistor 7 and supply a constant voltage power to the load 5.
