Title: Exponential function arithmetic unit
Inventor: KADOTA HIROSHI
IPC: G06F7/556
Filed: 1977-11-19
Abstract: PURPOSE: To operate exponential function a x  in a simple constitution by subtracting logarithm values generated successively in K=O to m in respect to a fixed K and storing the number of subtractions just before borrow generation correspondingly to K and continuing arithmetic operation.  
     CONSTITUTION: Logarithm values log a (1+N - R) where the base is a (a≠1) are successively generated in K=O to m by numeric value generator N, and memory circuit X stores an arbitrary positive integer. Then, logarithm values generated successively in K=O to m are substracted from contents of circuit X in respect to a fixed K, and the number of subtractions just before borrow generation is stored in memory circuit Y correspondingly to K. After arithmetic operation is completed, "1" is set to memory circuit Z to transfer contents of circuit Z by the number of subtractions corresponding to K and perform K-number-digit right shift, and the result is added to circuit Z. This operation is repeated in respect to K=O to m, thereby obtaining contents of circuit Z. As a result, exponential function a x  can be operated by a simple constitution.

Title: Regulator circuit
Inventor: OKAMURI KENTA
IPC: G05F1/56
Filed: 1980-10-03
Abstract: PURPOSE:To reduce the loss of electric power at a series regulator by flowing a current from a DC/DC converter and the transformer of a switching regulator to the Zener diode of the series regulator. CONSTITUTION:The transformer T of a switching regulator 1 is provided with another winding n3; its one terminal is connected to the emitter of the transistor (TR)Q1 of a series regulator 2, and the other terminal is connected to a common point through the series circuit of a diode D1 and a capacitor C1. A current i2 flowing through a Zener diode ZD is one obtained by dividing a voltage, regulated by the Zener diode ZD, by a resistance R1, i.e., a current free from fluctuations of an input voltage VS. In addition, the value of the output voltage Vc(=Va+Vb) of a rectifying and smoothing circuit 3 may be greater than a Vz, so the Vs can rise up to a level higher than the Va approximately by the saturation voltage (about 0.2V) of the TRQ1, reducing the loss of a voltage at the series regulator 2 greatly.

Title: Fuel injection pump for internal combustion engine
Inventor: JIYAN REPURANKU
IPC: F02M59/36
Filed: 1988-06-07
Abstract: PURPOSE: To make it possible to utilize inexpensive changeover valves which are low in speed of changeover and in output power by closing changeover valves during a suction stroke so that a plunger can be isolated from the tappet during a suction stroke. CONSTITUTION: A plunger 27 is forced to move toward the bottom dead center by the pressure applied by the fuel flowing into a fuel reservoir chamber by means of the release of a changeover valve 436 at the time of its suction stroke. Hence, when the changeover valve 436 is closed, the plunger 27 comes to a standstill in a position taken at that moment and only a roller tappet 28 in friction-contact with the cam track 15 moves up to the bottom dead center. When the roller tappet 28 returns after passing the bottom dead center, the plunger 27 is taken along by the roller tappet 28 again from its stop position and performs discharge. Thus, as during a suction stroke, closure of the changeover valve 436 is performed, utilization of the changeover valve 436 having a minimum speed of changeover and a minimum output power of changeover, can be made possible.

Title: Sheet for preventing dust depositing
Inventor: SUMI AKIRA
IPC: H01R13/52
Filed: 1994-06-21
Abstract: PURPOSE:To prevent generation of a power leakage resulting from deposited dust by providing a dust accumulation preventive sheet which consists of a soft insulating material having holes corresponding to the armatures of an attachment plug or a tap. CONSTITUTION:A sheet 17 for preventing dust accumulation is formed of a soft insulating material such as a rubber, an asbestos, a foaming polystyrol, and a cotton cloth. Two holes 19 corresponding to two armatures 13 of an attachment plug 3 are formed on the sheet 17, and the armatures 13 are inserted to the holes 19 when the plug 3 is inserted to a plug socket 5. By inserting the armatures 13 to the plug socket 5 by inserting to the holes 9 when the plug 3 is inserted to the plug socket 5, the sheet 17 is deformed being held by the plug 3 and the plug socket 5, so as to contact an armature projecting surface 3a and the plug socket 5 closely. Consequently, since no clearance is generated between both members, no dust is accumulated around the armatures 13 even though the sheet is used for a long period, and as a result, the generation of power leakage can be prevented.

IPC: B24B31/06
Filed: 1983-07-29
Abstract: PURPOSE:To completely remove the residue in an open used container, such as an open used drum, and completely clean the same for reuse, by burning the container and then pushing the same into an oscillating tank filled with grains of polishing and cleaning material. CONSTITUTION:A container 1 burned and immediately thereafter cleaned, or not cleaned, by means of shot blasting is held by a holder 4 with its opening turned downward and, handled by the holder 4 driven by a hydraulic apparatus or the like, pushed into polishing and cleaning material 3. After being left pushed in the polishing and cleaning material 3, which is oscillated, for a suitable period of time, the container 1 is pulled up and washed with water, whereby residue in the container 1 is washed away and the cleaning of the container 1 is thus completed. The lid of the container 1 having been removed therefrom is also cleaned following the same procedure. Thus, even a square container can be cleaned to each corner. Since the polishing and cleaning material does not attach to the container and readily comes off by action of electrostatic or magnetic force, complete cleaning of the container can be performed and therefore the container can satisfactorily be reused as a container of highly pure contents.
