Title: Semiconductor power converter
Inventor: KOSEKI SHOICHIRO
IPC: H02M7/48
Filed: 1994-11-04
Abstract: PURPOSE: To control DC components practically without affecting the fundamental waves of AC by turning on or off the pulses in the vicinity of ±90 deg. in phase angle, and changing the pulse width before or after it. CONSTITUTION: The carrier generated from a carrier generator 3 is represented, near -90 deg. in phase, by a straight line which becomes 0 at -90 deg. and has a gradient of -1/240 deg., and near 90 deg. in phase by a straight line which becomes 0 at 90 deg. and has a gradient of 1/120 deg.. In such carrier, the pulse generated from a PWM pulse generator 4 to the signal wave of sine wave K in amplitude is tuned on at -90 deg. expressed by an electric angle, and is turned off at 90 deg., and with this pulse signal, the on-off control of the arm of a converter 1 is performed, and AC voltage is generated. For controlling the DC components to be superposed on AC, the carrier is biased in the reverse direction so as to delay one when having advance the other only in regions near ±90 deg..

Abstract: PROBLEM TO BE SOLVED: To attain improvement in the reliability of cyclic transmission switching to a slave system in the case of master system fault by providing a mechanism for switching the setting area of a shared memory at another station to a transmission area, reception area or transmission/reception stop area. SOLUTION: A shared memory 6 writes/reads data from a host computer 4 of a present station 2 or writes data received from another station 2. A table 7 for transmission/reception setting stores the setting information of transmission area, reception area and transmission/reception stop area for each block of the shared memory 6. In this case, transmission/reception setting information is added for controlling the data transmission/reception operation of the other station 2 to transmission data by the instruction of the host computer 4 so as to transmit data to the shared memory area set to the transmission area by the other station 2. At the station to receive the data to which this transmission/reception setting information is added, this information is fetched and the data transmission/reception operation of the present station 2 is changed.

Title: Private part cleaning device
Inventor: FUJISHIMA YUKIHIRO
IPC: H02J13/00
Filed: 1999-09-27
Abstract: PROBLEM TO BE SOLVED: To reduce the consuming power of private parts cleaning device in a washroom by connecting it with an illumination server detecting the operating condition of illumination equipment provided in a home through a communica tion line, and controlling power ON and OFF based on a signal from the illumi nation server. SOLUTION: This private parts cleaning device is formed so that a server 6 may determine that a person has started operation if any of illuminators 1 to 5 comes on and transmission may be performed with a communication line connected to a private parts cleaning device 11, called W/L, from the server 6. If present time on a 24-h timer built in is determined as 'not at night', W/L 11 power supply is turned on. In the case of 'at night', when the server 6 determines that consuming power of the respective illuminators is lower than an inputted setting value, it is determined as 'off' to turn off the power supply of W/L 11. It is thus possible to prevent the consuming power of the private parts cleaning device from increasing.

Title: Production of soft ferrite
Inventor: OKUNO KEIZOU
IPC: H01F1/34
Filed: 1990-10-12
Abstract: PURPOSE:To increase molding density and control and adjust contraction rates by either mixing calcinated powders processed under differing calcination conditions at a specified ratio before crushing or mixing after crushing. CONSTITUTION:After mixing the main elements of soft ferrite, oxides and carbonates or other compounds, at a specified ratio, the calcination process is performed under multiple, different temperature conditions. For example, when a powder calcinated at 850 deg.C is mixed with a powder calcinated at 950 deg.C in different ratios and minutely moisture crushed to particles with an average diameter of 1.0-1.2mum, a toroidal is formed, and sintering is performed at 1350 deg.C, the sintered core density is nearly uniform. With this method, it is possible to obtain materials with different contraction rates and thus to improve contraction rates by varying the ratios of the mixture. This effect can also be obtained by mixing at a set ratio after crushing a sintered material processed under different conditions.

IPC: B41J2/325
Filed: 1992-10-12
Abstract: PURPOSE:To obtain the device high in reliability at a low cost and improve the printing quality thereof by providing an ink containing body made of a thermo-sensitive liquid- absorption resin which is an expansion and liquid-absorption state at not higher than a transition temperature and a contraction and liquid-discharge state at higher than the transition temperature. CONSTITUTION:An ink containing body 4 comprises on a base film 4a a layer of a thermo-sensitive liquid-absorption resin 4b having a horizontal porous structure of desirable thicknesses of gels. When it is brought into contact with an ink at not higher than a transition temperature, it becomes an expansion and liquid-absorption state and holes 4c disappears so that the porous structure goes out of existence. The base film 4a of the ink containing body 4 is brought into contact with opposed heating elements 1a at a transferring section. When recording signals are applied to the heating elements, each of the heated heating elements raises the temperature of the thermo- sensitive liquid-absorption resin 4b corresponding to the heated position beyond the transition temperature and allows it to become a contraction and liquid-discharge state so as to become a porous structure wherein the in the hole 4c is discharged. When the ink is further heated beyond the boiling point, bubbles 8 are generated in the ink 7 so that an ink droplet 7a is ejected.

Title: Production of electronic component
Inventor: ARITA TAKASHI
IPC: H01C17/06
Filed: 1990-10-12
Abstract: PURPOSE:To obtain stable and uniform electronic parts by printing a resistance paste or conductive paste (electrodes) on a substrate, baking in a vapor chamber at a low temperature to prevent bubbling, and then baking in a vapor chamber again at a higher temperature for hardening. CONSTITUTION:A resistance or conductive paste printed on a substrate in order to form a resistor is baked in a vapor chamber with a low temperature to prevent the formation of bubbles on the film surface caused by bumping from the heat, for example a vapor chamber 1 with an inert solvent that has a boiling point of 102 deg.C, and is then baked a second time in a vapor chamber at a higher temperature for hardening, for example a vapor chamber 2 with an inert solvent that has a boiling point of 215 deg.C. This method can also be used for the baking of conductive paste for membrane switches or copper paste and other polymer thick film pastes for EMI shields. Also, when a cooling element using the cooling coil 6 is established between the vapor chamber 1 and vapor chamber 2, it is possible to reduce the amount of inert solvent used. By conducting all heating in the vapor chambers, uniform and stable temperatures are achieved and baking can be completed in a short time with excellent heating efficiency.
