Title: Chaft bullet
Inventor: IGARASHI TOMIO
IPC: F42B12/32
Filed: 1978-01-23
Abstract: PURPOSE:To provide a chaff bullet, in which a shooting unit is arragned between the propelling unit and chaff cartridge so as to make the most efficient use of pressure developed by shooting powder, whereby it is enabled to detach the chaff cartridge from the shooting unit in reliable manner. CONSTITUTION:When propelling unit d of a chaff bullet is ignited, it is shot into the air and travels to an aimed place. Then, propelling unit D ignites shooting powder 35 by the aid of firing wire 37, whereby shooting unit C is set into operation and its combustion gas is filled in the vicinity of a fixing member 32 in the outer sleeve F of chaff bullet. By the pressure of the combustion gas, chaff cartridge A, capsule E coupled with the chaff cartridge A and chaff cartridge igniting unit B are detached from the propelling unit D and shot away therefrom. On the other hand, firing wire 31 is ignited by the shooting unit C, and powder 30, igniting powder 26 and time delaying powder 25 are ignited successively. After passing of a predeermined time period, powder 6 is exploded and high-temperature and high pressure gas is filled in the outer sleeve 2. When the pressure in the outer sleeve 2 exceeds a certain level, outer sleeve 2 is ruptured and chaffs are scattered uniformly in every direction and in a wide range.

Title: Bonding of polyvinyl chloride leather and natural rubber
Inventor: YAMANAKA YASUHIRO
IPC: D06N3/18
Filed: 1989-01-13
Abstract: PURPOSE:To firmly bond a polyvinyl chloride leather and a rubber article without using a primer while suppressing the generation of tackiness by coating a polyvinyl chloride leather with an adhesive composed of a natural rubber graft-polymerized with methyl methacrylate, contacting a rubber article to the coated surface and vulcanizing the adhesive with heat. CONSTITUTION:For example, a vamp made of a polyvinyl chloride is coated with an adhesive composed of a natural rubber graft-polymerized with methyl methacrylate (e.g. MG49 having a grafting degree of 49%) and a sole- circumference tape made of natural rubber is bonded to the coated surface by thermal vulcanization. Both components are bonded with each other owing to the coincidence of the polarities of the polyvinyl chloride and the methyl methacrylate-grafted natural rubber. The adhesive squeezed out of the bonding surface is free from tackiness even after the lapse of time to prevent the deposition of dust and provide the product with excellent appearance.

Title: Motor
Inventor: YAMAZAKI KENJI
IPC: H02P6/08
Filed: 1979-01-26
Abstract: PURPOSE: To obtain a simple structured motor to be driven through a high frequency without deteriorating the efficiency by a method wherein a commutator element is installed in parallel to add the fly wheel effect in a series circuit composed of stator windings and switching elements.  
     CONSTITUTION: In the running state of a motor, the transistor 4 is, in high speed, repeating the power supply through the high frequency clock pulse signal X, therefore, the high frequency pulse voltage is constantly being applied to the stator windings 1U∼1W. Each phase transistor is placed in the continuity state by each phase driving signal and the power supply is performed in response to the switching of the transistor 4. When it is ON time, current is supplied through the transistor 4 and when it is OFF time, the accumulated energy of the windings is discharged through the diode 5, therefore, the power supply is substantially maintained. On this account, the running efficiency is improved and the torque pulsation prevention effect is increased, thus, permitting to obtain the motor which is capable of driving through high frequency.

Title: Control device of inverter
Inventor: MATSUOKA KOICHI
IPC: H02P7/00
Filed: 1990-01-17
Abstract: PURPOSE:To enable execution of smooth transfer to a commutation advance control and to enable execution of a wide-range control by providing a first switch selecting either an output of a phase-difference-zero control circuit or a reference signal and a second switch selecting either an input of a detection signal or a feedback from the aforesaid phase-difference-zero control circuit. CONSTITUTION:Below a prescribed number of revolutions, change-over switches 1 and 19 operate so that an output signal be synchronous with a reference signal, and a closed loop is formed. When the prescribed nuber of revolutions is reached, the change-over switches 1 and 19 are changed over, and the change over is smooth since the reference signal equals the output signal just before the changeover. Although an armature current is retarded by some electrical angle from the reference signal, frequencies thereof are the same. After the changeover, a PLL control element 20 starts to operate so as to correct the retardation and gives commutation advance compensation to the output signal and thereby the armature current is made synchronous with the reference signal.
