Title: Head driver for ink jet recorder
Inventor: UMENO KOJI
IPC: B41J2/205
Filed: 1994-12-26
Abstract: PURPOSE: To give gradation-expression of an image by periodically outputting a plurality of driving voltages of different levels to a recording head for discharging ink by the deformation of a piezoelectric element at different timings, selecting the driving voltage corresponding to the gradation of the image of the driving voltages, and applying it to the element. CONSTITUTION: An image memory 30 stores multi-valued image data in which ink discharge quantities from ink discharge nozzles corresponding to piezoelectric elements 101 to 105 sequentially become an intermediate, small, zero, large and intermediate quantities, and the data are inputted in parallel from the memory 30 to a head driving circuit 40. That is, timing selectors 401 to 405 output select signals at the times for outputting the voltage from a driving voltage generator 20 according to the inputted multi-valued image data so that suitable quantities of ink are discharged from the ink discharge nozzles corresponding to the elements 101 to 105. The drivers 501 to 501 apply the voltages to the elements 101 to 105 at the times. Thus, the image having the gradation can be recorded at the nozzle unit.

Title: Production of zeolite adsorption separating agent
Inventor: HARADA ATSUSHI
IPC: C01B39/22
Filed: 1990-11-28
Abstract: PURPOSE:To obtain a zeolite adsorption separating agent having high adsorption capacity without losing the adsorption capacity of the zeolite powder as possible by calcining a zeolite molded body in a gas flow having -30 deg.C or lower dew point. CONSTITUTION:The zeolite molded body to be calcined may be a molded body comprising a material not calcined or already calcined. As for a uncalcined molded body, a dry molded body is used, which is prepared by usual molding method and dried. The flowing gas is introduced to a tower packed with a drier such as zeolite to remove water in the gas and to make the dew point of the gas to -30 deg.C or lower. If the molded body is calcined in a gas having the dew point higher than -30 deg.C, the adsorption capacity of the calcined body decreases by about >=10% compared to the estimated value from the adsorption amt. in a powder state. Decrease in the adsorption amt. can not be suppressed even by increasing the flow amt. or speed of the gas, or calcining time. On the other hand, by calcining in a gas flow of -30 deg.C or lower dew point, decrease in the adsorption amt. is at most 5%. Further, by controlling the gas flow amt., decrease in the adsorption amt. can be reduced.

Filed: 1997-11-07
Abstract: PROBLEM TO BE SOLVED: To provide two AC power supplies which have a prescribed phase relation between them at a fixed voltage even with ambient temperature changes or load variations by comparing the output of a peak holding circuit with a reference voltage and controlling the variations of the output voltage. SOLUTION: If the sine wave amplitude of an output voltage VO1 of an output terminal 9, is reduced by a load variation, the output voltage Va1 of a peak holding circuit 3 reduces and the output Vd1 of an integration circuit 6 rises. Thus, the sine wave voltage of an amplifier 2 rises. The sine wave outputted from the amplifier 2 is transmitted via a secondary LPF 11, a voltage converter 14, etc., and the 2nd AC power output voltage VO2 is obtained from an output terminal 15. The phases of VO1 and VO2 are kept at a fixed angle, e.g. 90 degrees. If the sine wave amplitude of VO2 is reduced by the load variation, the voltage Va2 of a peak holding circuit 16 decreases and the output Vd2 of an integration circuit 17 increases Thus, the sine wave voltage of a power amplifier 13 rises.

IPC: H01L51/30
Filed: 1995-12-12
Abstract: PROBLEM TO BE SOLVED: To provide a flat panel made of thin film transistor electroluminescence(TFT-EL) picture elements. SOLUTION: Two TFTs and a memory capacitor are utilized, so as to keep EL picture elements on a panel operable nearly at a 100% duty factor.

IPC: H04L12/28
Filed: 1999-11-12
Abstract: PROBLEM TO BE SOLVED: To accurately notify a host device that data are received in spite of the specification that mainly the host device inputs and outputs data. SOLUTION: A BS signal is switched over to an H level at a time t1, and a radio I/F detects a BS0 in accordance with the level change of the BS signal from the host device at a time t2 and the start of a BS0 period. The BS0 period is a period when packet communication is not performed. At a time t3, the BS signal is shifted to an INT (interrupt) transfer state. When an incoming call is detected at a time t4, it is registered in an INT register that the incoming call occurs and an interrupt request is also outputted to the host device. At a time t4, the interrupt request is outputted to the host device and an SDIO signal becomes an H level. Within the BS0 period, the interrupt request is outputted to the device 4 while notifying that the data are received.
