Title: Method of rewriting nonvolatile memory
Inventor: SATO KAZUO
IPC: H01L21/8247
Filed: 1988-06-22
Abstract: PURPOSE:To substantially increase a number of possible rewriting operations in an EEPROM having floating gate structure, by baking the EEPROM always after repeating a certain number of rewriting operations. CONSTITUTION:A floating-gate-type EEPROM assembled into a package is subjected to up to 10<5> rewriting operations by a conventional rewriting process. The EEPROM in the packaged state is then introduced into a baking furnace at a temperature higher than 200 deg.C and left therein for about 5 hours. The EEPROM is taken out of the furnace and subjected to 10<5> rewriting operations by an ordinary rewriting process. Then, the EEPROM is baked again. By repeating this cycle, a number of possible rewriting operations can be increased substantially.

Title: High frequency voltage detecting circuit
Inventor: MORIYA YOUICHI
IPC: G01R19/04
Filed: 1978-12-06
Abstract: PURPOSE: To enable ready adjustment of a time from the entrance and vanishment  of an AC voltage to the generation and vanishment of an output signal in a high frequency voltage detecting circuit by providing a transistor conducting and shutting off by the voltage at a smoothing capacitor.  
     CONSTITUTION: First smoothing circuit is formed by resistors R 1 , R 2  and a capacitor C, and second smoothing circuit is formed by resistors R 3 , R 4  and a capacitor C 1 . The capacitor C 1  is connected to a transistor (Tr) 12 at its base to control the operation of the transistor 12 by the voltage at the capacitor C 1 . When an AC voltage is applied to a termianl 1, the capacitor C 1  is charged to thereby cut off the transistor 12, and the capacitor C is charged at the time constant of τ 1 '=R 1 C. When the AC voltage becomes zero volt, the transistor 12 is conducted to cause the capacitor C to dischrage at the time constant of τ 2 '=R 2 C(R 1 ≫R 2 ). Since the delay times τ f , τ r  are set by the time constants τ 1 ', τ 2 ', it can be readily set τ f >τ r  in case of R 1 ≫R 2 .

Title: First charge control method for lead-acid battery
Inventor: MORIMOTO YOSHINARI
IPC: H01M4/22
Filed: 1986-06-30
Abstract: PURPOSE:To increase efficiency of charging and to increase durability of a cathode plate by controlling charging voltage in starting of the first charge. CONSTITUTION:Usually, the first charge of this kind of a battery is performed by passing a specified quantity of electricity at a constant current. Since current is passed in an active material which is electrochemically inactive because of no formation, internal resistance of the battery becomes very high, and current distribution is concentrated in the vicinity of a grid made of lead alloy, and after starting of the first charge, melt-bonding of the grid with active material is generated in both electrodes. This has an adverse effect on charge efficiency and battery performance. In order to remove this disadvantage, in starting of the first charge, voltage per battery is controlled to 2.5V or less. Thereby, concentrated evolution of oxygen gas in the vicinity of the grid is retarded, and decrease in adhesion of the cathode grid with active material can be prevented, and deep charge-discharge cycle life can be improved.

Abstract: PURPOSE: To adjust an output pressure by comparing the pump pressure detected by a pressure transducer with standard pressure, turning on or turning off a clutch to shift pressure deadband of upper and lower limits while turning on the clutch during the output being small in a pressure control loop apparatus for a portable spray painting equipment. CONSTITUTION: Paint supplied from a container to a paint inlet 14 is supplied to a paint spray gun 13 after pressurized by a piston pump 16.

The outlet pressure is compared there with a predetermined pressure and with the upper and lower limits of the deadband. If the output pressure is less than the predetermined pressure, an electromagnetic clutch 32 is turned on to set the pressure. Therefore, the pressure deadband controller shifts the deadband from a high level to a low level during the clutch turned off, and on the contrary, it shifts the deadband from low to high while the clutch is turned on.

IPC: B01F25/74
Filed: 1982-09-03
Abstract: PURPOSE:To obtain continuously an emulsified liquid having high quality even from a liquid dispersed phase which is highly viscous or is solidified at an ordinary temp. in a device for atomizing electrostatically the liquid dispersed phase in a liquid continuous phase which flows downward by using a rotary atomization head and supplying hot wind to the surface thereof for receiving the liquid dispersed phase. CONSTITUTION:An atomization head 12 is rotated at a high speed with an air motor 17, and hot wind is supplied from hot wind sources 31, 33 to the receiving surface 13A of the atomization head and from a hot wind source 37 toward the atomization head, respectively. The liquid continuous phase in a tank 10 is supplied through the annular passage 7 and many small holes 8 of a supply pipe 6 toward the thin film forming surface 2 of an emulsification tank 1 where the water is flowed downward along the surface 2 and the thin water film is formed. When the highly viscous liquid dispersed phase in a tank 26 is dropped to the surface 13A of the atomization head, the liquid is kept at a low viscosity as said surface is kept heated; therefore, the liquid flows out through an outflow port 13B to a diffusion surface 14A. While the water flows on the surface by centrifugal force, a thin water film is formed to a uniform thickness and is thus atomized. The particles thereof are incorporated into the thin liquid continuous phase film on the surface 2 and are thoroughly dispersed. The emulsified liquid is thus captured in a tank 4.
