Filed: 1980-04-10
Abstract: PURPOSE:To make toner charging uniform and prevent uneven developing by providing a fur brush roller for developing, a brush roller for toner supplying and a charger, and subjecting the toner to frictional charging and electric charging. CONSTITUTION:A fur brush roller 28 for developing and a brush roller 29 behind this are provided in a roller chamber 26.

Title: Battery with lead terminal
Inventor: HARA MITSUYA
IPC: H05K3/34
Filed: 1996-03-05
Abstract: PROBLEM TO BE SOLVED: To improve the soldering of a lead terminal for an electric circuit board and the welding of a lead terminal for an element battery by differing the thickness of a positive terminal side lead terminal from the thickness of a negative terminal side lead terminal in a battery. SOLUTION: In a battery with a read terminal, the thickness of a positive pole side lead terminal 10 differs from that of a negative terminal side lead terminal 9. If there is a difference between the allowable welding outputs of the positive and negative pole terminal sides, it is preferable that the thickness of the lead terminal on the terminal side of the unit cell with its low allowable welding output is thin and the thickness of the lead terminal on the terminal side of the unit cell with its high allowable welding output is thick. It is preferable that the lead terminal on one pole terminal side of the unit cell is of stainless steel 005 to 0.15mm in thickness and that the lead terminal on the other pole terminal side of the unit cell is of stainless steel of 0.15 to 0.4mm in thickness. Since the lead terminal on one pole terminal side is thin and is superior in flexibility, soldering to the electronic circuit board is improved.

Filed: 1988-02-29
Abstract: PURPOSE:To shorten the start-up time of an optical disk and to accelerate the operation of a system by increasing a friction coefficient in a clamping area by extending a part of a center hub to the clamping area. CONSTITUTION:Each center hub 3 is constituted of a main body part 3a and a flange part 3b extended in a circumferential direction at the outer peripheral part of the main body part, and those main body part 3a and flange part 3b are formed integrally with the same material.

The static friction coefficient of the SUS440C and the polycarbonate is larger that of glass, which provides around a double friction coefficient, and slippage can be suppressed by the increase of the friction coefficient. In such a way, it is possible to shorten the startup time and the stopping time of the optical disk, and to accelerate the operation of the system.

Title: Semiconductor device and manufacture thereof
Inventor: NAKAYAMA RIYOUZOU
IPC: H01L29/78
Filed: 1983-03-23
Abstract: PURPOSE:To compensate the decrease of MOSFET characteristics by arranging a conductor film from on an n<+> diffused layer to an n<-> diffused layer and thus obtain excellent MOSFET characteristics by a method wherein the parts of the source and drain diffused layers on the gate region side are made as n<-> diffused layers of low concentration. CONSTITUTION:Pt silicide films 301 and 302 are arranged on the source and drain diffused layers from on the low resistant n<+> layers 281 and 282 to the high resistant n<-> layers 251 and 252. Thereby, the decrease of drain current and that of gm due to providing the n<-> layers 251 and 252 on the gate region side are compensated. Therefore, while sloving various kind of problems caused by fine processing, the excellent characteristic of the MOSFET can be secured. For example, a Pt silicide 303 is superposed also on the gate electrode 24, and then action at much higher speed than that of the MOSFET is enabled by reducing the resistance of the gate electrode. Further, since the source and drain electrodes 32 and 33 contact the Pt silicide films 301 and 302 respectively, the contact resistance of this part is small, and this fact is contributed to the improvement of the MOSFET characteristic.

Title: Defect detector for thyristor
Inventor: MATSUMURA SUSUMU
IPC: H02M1/00
Filed: 1982-03-26
Abstract: PURPOSE:To reduce the number of long distance wirings by converting the number of defects of the thyristors to the light emitting amount of a light emitting diode, thereby transmitting the number of the defects of the thyristors through a optical fiber. CONSTITUTION:Since all phototransistors 16, 26, 36,... turn ON so that resistors 17, 27, 37,... corresponding to respective thyristors 10, 20, 30,... are all shortcircuited when all thyristors 10, 20, 30,... are normal, the maximum current which is determined by the resistor 61 is flowed to a light emitting diode 62, which emits the light of the highest intensity. When any of the thyristors becomes defective, the phototransistor which corresponds to the defective thyristor turns OFF, thereby causing the light emitting amount of the diode 62 to be reduced. The light emitted from the diode 62 is transmitted via an optical fiber 63. When the number of the defective thyristors becomes not less than the prescribed value, a defect detection signal is outputted from a voltage comparator 65.
