Inventor: TAKEUCHI SHIGEKI
IPC: G03G5/08
Filed: 1986-02-10
Abstract: PURPOSE:To obtain a photosensitive body superior in sensitivity in the near infrared region by regulating the difference between the optical energy gap between the interlayer between an electrostatic charge transfer layer and a charge generating layer and its adjacent layer, and the band gap between a vacuum level and the valence electron band to a prescribed value or lower.

Title: Automatic gain control amplifier
Inventor: SASAKI SUSUMU
IPC: H03G3/30
Filed: 1978-03-10
Abstract: PURPOSE:To eliminate probability that unstable operation of oscillation, etc., is caused while having small compressibility, by attaining constant gain amplification with an AGC control current suppressed to a constant value when a detection becomes below an inferior threshold level. CONSTITUTION:Controller 13 is provided between detector 11 detecting an output signal and buffer unit 12 converting this detected output into an adequate current value. The output signal is applied as an AGC control current to respective control amplifiers 2-1 to 2-n by way of detector 11 and buffer unit 12. At this time, controller 13 when the detection 11 output becomes below a fixed value controls buffer unit 12 to suppress the AGC control current to a constant value and, in consequence, the operation gain of the AGC amplifier decreases down to a constant value, so that the unstable-operation state can be avoided. Next, if a signal of more than the constant value arrives in this state, controller 13 detects that the detection 11 output becomes above the constant value and resets the above-mentioned suppression on buffer unit 12. As a result, the AGC control current increases and the AGC amplifier returns the original gain state, thereby starting the AGC operation.

Title: Watch having resetting function of needles
Inventor: UCHINO MISAO
IPC: G04C3/14
Filed: 1978-03-10
Abstract: PURPOSE: To reset needles of a watch without standard watch by resetting the needles based on the data stored at needle operating time.  
     CONSTITUTION: When the stem of a watch is used to turn needles of the watch so as to set a mode switch 37 to set time of alarm time or the like, the indicated position data at the time is latched to latch circuits 80, 81. After finishing the set, the switch 37 is released. Then, when a return key 70 is depressed, arithmetic circuits 82, 83 of a resetting circuit 102 calculate the sum of the time counting value of correcting counter 78 as to the period from the closure of the switch 37 to the release thereof and stored content of the circuits 80, 81 to apply it to a comparator 77. In the meantime, the needle position data are applied from needle position detecting converter 38, 39 due to the rotation of the needles by a timing counter 8 and drive circuit 9 to the comparator 77 to drive the needles until the compared content of the comparator 77 becomes zero. Accordingly, the needles can be reset without standard watch.

IPC: G11C11/406
Filed: 1997-02-12
Abstract: PROBLEM TO BE SOLVED: To compensate for the bits which are weak in the memory retaining capability of a dynamic memory circuit on an integrated circuit. SOLUTION: A memory element which is weak in memory storing capability in the memory array 12 is identified by the well known test program. This memory element means bit (cell), block or the other portion of the memory array 12. Position information of the identified memory element having weak memory retaining capability is programmed by the refresh address generators 30, 32 and block identification address generator 35 and this position information is used for refreshing the memory element having weak memory storing capability at a speed different from that of the other memory element. Therefore, the refresh interval of the memory element having weak memory storing capability is shortened and meanwhile, refresh interval of the memory element having strong memory storing capability can be elongated.  As a result, the refresh interval of the memory array 12 as a whole can be set longer than the ordinary refresh interval.

Abstract: PURPOSE:To prevent arsenic decrease of a substrate caused by annealing, and reduce the surface roughening and the deterioration of electric characteristics by using an indium arsenide substrate as a susceptor for annealing a gallium arsenide semiconductor device substrate. CONSTITUTION:A gallium arsenide semiconductor device substrate 13 and an indium arsenide substrate 14 are so arranged on a holder 12 that the surfaces of them overlap with each other. The gallium arsenide semiconductor device substrate 13 and the indium arsenide substrate 14 are arranged in a furnace core 11 of nitrogen atmosphere, and irradiated at 700-800 deg.C with infrared rays from the outside of the furnace core 11, thereby quickly heating the substrates and annealing the gallium arsenide semiconductor device substrate 13. Since the indium arsenide substrate 14 has arsenic pressure higher than that of the gallium arsenide semiconductor device substrate 13, sufficient arsenic is supplied to the surface of the gallium arsenide semiconductor device substrate 13 by the annealing. As a result, the surface roughening and the deterioration of electric characteristics caused by arsenic decrease of the semiconductor device formed on the substrate are remarkably reduced.
