Inventor: TAKAI MEIJI
IPC: H01F27/10
Filed: 1981-11-05
Abstract: PURPOSE:To provide a foil wound transformer which has enhanced cooling capability and is resistive to a mechanical force in the radius direction by improving close contact property between metal foils and between metal foil and cooling duct. CONSTITUTION:At the outer most circumference of the foil winding comprising a cylindrical hollow cooling duct 6 where a metal foil 2 and insulating sheet 3 are overlappingly wound and plurality of pairs of cylindrical or arc shaped material not forming a turn are combined between desired windings thereof, a shield 14 is provided in order to ease concentration of field at the upper and lower edges of the circumference of foil winding. Said shield 14 is closely fixed at the external side of foil winding by winding a thermally compressive tape 15 at the circumference. Therefore, since the thermally compressive tape 15 contracts by a heat generated by the winding, contact property between metal foil 2, insulating sheet 3 and cooling duct 6 are improved, thereby remarkably stabilizing thermal conduction characteristic from the metal foil 2 to the cooling duct 6.

Title: Waveform storage circuit and musical sound synthesizer
Inventor: KUNIMOTO TOSHIFUMI
IPC: G10H1/00
Filed: 1990-07-04
Abstract: PURPOSE:To obtain a high-quality musical sound waveform when musical sound waveforms are synthesized based on stored waveforms by storing the musical sound waveforms at a high S/N without increasing the number of elements required for the storage. CONSTITUTION:A 24-bit waveform value outputted from an adder 1 is inputted to the first added input terminal and the higher-rank 16 bits of the 24-bit output value of an adder 5a are inputted to a delay circuit 2 as a quantized waveform value, with the remaining lower-rank 8 bits, namely, a quantization error is inputted to another delay circuit 5b. When such a quantization circuit 5 is used, quantization is preformed on values obtained by adding waveform values inputted at every sampling period to the quantization error accumulated values at every sampling period and accumulation is performed on quantization errors produced at every quantization. Since the output waveform value of the adder 1 is quantized after the value is corrected by means of the accumulated value of quantization errors, occurrence of distortions by quantization errors can be prevented and high-quality attenuated sounds can be obtained.

Title: Compressor
Inventor: WAKABAYASHI TOSHIO
IPC: F04C29/06
Filed: 1981-10-31
Abstract: PURPOSE:To obtain a lightweighted compressor and reduce its noise by installing an normally closed valve outside the gas discharge hole on a compressor body and making said normally closed valve and a muffler from ceramic material. CONSTITUTION:A crank shaft 9 is revolved through revolution of a motor 12, and the rotary piston 4 in a compressor body 2 revolves eccentrically. The gas compressed at this time operates to open the normally closed valve 14 installed onto a bearing 11 and is discharged once into a muffler 15 after passing through  a gas discharge hole 13, and then the pressure pulsation of gas is etc. attenuated by the muffler, and after the noise such as pulsation sound of the valve 14 is cut-off, the gas is discharged into a shell 1 from the discharge hole 17 of the muffler. As ceramic material possesses a number of covalent bonds having a larger atomic bonding force than that of the metal bond, the muffer 15 made of ceramic is highly effective to cut-off the noise by suppressing the pressure pulsation of gas by its volume effect, and is further advantageous with its light weight.

Abstract: PROBLEM TO BE SOLVED: To facilitate control of ink discharging amount and speed by operating an attraction force or repulsion force between a coil and a magnet, hence deforming a diaphragm to apply pressure to the chamber, and externally discharging ink via a nozzle. SOLUTION: When a printer signal is applied to a coil 122, the coil 122 is deformed upward together with a diaphragm 120 in an arch state by a repulsion force generated between a fixed permanent magnet 110 and the coil 122. Pressure is operated in ink 144 in an ink chamber 142 by deformation of the diaphragm 120, and hence ink droplet (bubble) is discharged through a nozzle 132. A deforming amount of the diaphragm 120 at this time is altered according to an amplitude of an electric signal to be applied to the coil 122. Accordingly, ink amount and discharging velocity to be discharged can be easily controlled by regulating an electric signal to be applied to the coil 122.

Filed: 1990-07-05
Abstract: PURPOSE:To miniaturize a device main body by integrally providing a developer storing means and a residual developer containing means and making them freely attached to/detached from the device main body. CONSTITUTION:The developer storing means 6 and the residual developer containing means 7 are integrally provided to be freely attached to/detached from the device main body. In such a case, when the cover of the device main body is opened, an electrophotographic process unit consisting of an image carrier 1 and an elecrifier 2 moves upward and the automatic opening and closing part 8 of the cleaner 7 is closed with the movement.
