Title: Resin-sealed type semiconductor device
Inventor: UJIIE MASATO
IPC: H01L21/60
Filed: 1990-03-27
Abstract: PURPOSE:To prevent the pushing and wash-out of a semiconductor element by a resin and to prevent electrical opening and shor circuit defects when a device is sealed with the resin by fixing a semiconductor element to a part of each inner lead through brazing filler metal. CONSTITUTION:A semiconductor element 1 is connected with an inner lead 2a of each lead 2 without a semiconductor mounting part and each metal thin wire 3.

Inventor: HARAGUCHI EIJI
IPC: H02P9/00
Filed: 1986-04-07
Abstract: PURPOSE:To stably control a variable speed pumping-up generator plant to a target value at AFC operation time by operating it with a rotating speed determined by a power command value and an effective head and a governor valve opening. CONSTITUTION:A block 25 obtains an optimum valve opening and an optimum rotating speed by an effective head H and an output command P0. The output of a speed governor 24 which responds to the difference between the optimum rotating speed and the actual rotating speed N is applied to an output command value P0 in the block 25. The optimum valve opening is applied to a servo system 14 to become the valve opening of a governor. A secondary winding phase angle calculator 16 calculates a phase angle by the effective power, actual rotating speed and the output of the block 25 to apply it to a setter 17 for setting the exciting amount of a secondary circuit.

Title: Electrostatic recording system
Inventor: OONISHI RIYOUICHI
IPC: B41J3/00
Filed: 1978-06-27
Abstract: PURPOSE: To enable a steady changing of printing dot sizes even if there is the change in enviroment condition and power source voltage, by changing the polarity of a recording signal which is applied between a needle-electrode and a control- electrode.  
     CONSTITUTION: For example, a printing dot at a negative polarity is determined as a state 1, a printing dot at a positive polarity as a state 1/2, and a non-recording dot as a state 0. The state 1 picture signal unit applies a negative voltage from a negative recording power source 8 to a multi-needle recording electrode 4 and a positive voltage from a positive recording power source 9 to a control-electrode 5 respectively, and forms a printing dot of the negative polarity having a large diameter. A state 1/2 picture signal unit applies the positive voltage and the negative voltage to the electrodes 4 and 5 respectively, and a printing dot of the positive polarity having a small diameter can be formed. Furthermore, a state 0 picture signal unit turns off all switches and non-recording may result. A charge pattern is thus produced on a dielectric layer, and subsequently is developed and fixed.

Title: Substrate for forming semiconductor film and semiconductor device using the same
Inventor: SHINRAKU KOUICHIROU
IPC: H01L27/12
Filed: 1997-03-31
Abstract: PROBLEM TO BE SOLVED: To enable crystal growth at a sufficiently high speed and supply an inexpensive thin film crystal silicon substrate, by sequentially stacking a crystal oxide layer containing aluminum or the like and a crystal silicon layer on a main surface of a base, and thus carrying out crystal silicon growth of a thin film at a relatively low temperature. SOLUTION: First, a thin film crystal silicon layer 5 is formed on a glass substrate 1 with an Al2 O3 layer 4 provided between the layer 5 and the substrate 1. Next, using the thin film crystal silicon layer 5 as a first silicon layer, a second thin film crystal silicon layer 6 is stacked thereon by using a vacuum film forming technique such as a CVD method. The two-layer structure is formed for the following reason. That is, if there is only a lower layer, the doping impurity concentration is too high and recombination of carriers due to an Auger recombination mechanism becomes problematical. Thus, it becomes difficult to obtain the quality suitable for an optical active layer of a solar battery.  The surface of the optical active layer thus obtained is dry-etched by using a RIE method, and a semiconductor forming substrate S having a rough surface of a randomly recessed and protruding structure is provided.

Abstract: PURPOSE:To prevent the semiconductor element handling region of a cleaning device from invasion of dust by a method wherein the open area of an air outlet is made smaller than the open area of an air inlet. CONSTITUTION:A clean hood 2 is installed at the top part of a semiconductor element manufacturing device 1 to introduce positively clean air to flow down toward the floor D from the ceiling U right over the device 1, an air inlet 2a is opened at the top part of the hood 2, and an air outlet 2b is provided at the under part of the hood 2 positioning between the handling region S1 and the working region S2 of a semiconductor element. Because the open area of the air outlet 2b is set in a smaller diameter than the open area of the air inlet 2a, an air current is contracted to enhance pressure at the air outlet 2b. Accordingly, pressures at the handling region S1 and the working region S2 are made to be in relation S1>S2, and invasion of dust to the semiconductor element handling region S2 is arrested.

In this device, a transmitter successively measures the polarized states of the first and second photons appearing at the same time, and transmits the measured result through a classic communication path to a receiver. On the other hand, the receiver reproduces the coefficient of the polarized state of the first photon from the successive measured results of the polarized states of the second photon and a third photon correlatively appearing according to a quantum theory and the transmitted measured result, and extracts information. Thus, quantum cipher communication highly protected from eavesdropping can be attained.

Title: Program retrieving device
Inventor: IWANABE TERUKAZU
IPC: G11B27/10
Filed: 1979-06-21
Abstract: PURPOSE: To reduce greatly the period of the program to be retrieved, by dividing the retrieving period into two sections and then giving the high-speed driving to these two sections in the different speed each.  
     CONSTITUTION: Magnetic head H detects the silent part when retrieving the program on magnetic tape T, and the detection output is led into detection circuit IC 1 . When the silent part continues more than the fixed length, IC 1  leads the signal out to the output part. And shift register IC 2  shifts the memory information in sequence with every application of the output of IC 1 . In case the No. n program is retrieved, the low level is secured only for the potential at the output terminal of the No. n digit by the opration of the corresponding key. Thus only LEDn glows to store the retrieval of the No. n program. The 1st-class high-speed driving is carried out in a higher speed than the 2nd-class one, and the programs of the 1st to the No. (n-1) orders are driven. And the 2nd-class high-speed driving is given to the No. (n-1) program. And when the silent part is detected up to the No. n order, the automatic reproduction is secured for the No. n program by the operation of solenoid S.
