Title: Vibration isolator
Inventor: INOUE KIYOSHI
IPC: F16F15/02
Filed: 1987-05-06
Abstract: PURPOSE:To instal the device in the title to any vibrating body easily for making it possible to detect vibration by irradiating a vibrating body with laser beam focusing on it for detecting reflected beam from the vibrating body with an optical detector. CONSTITUTION:When the focus coincides with a refracting surface, a laser beam reflects totally and is refracted in right angle by a half mirror 6 and passing through a lens 18, detected by an optical detector 8 but when the reflecting surface moves owing to vibration, the focus is drifted so no reflected beam becomes to return. So, as signal in the optical detector 8 disappears in this case, the reflecting surface moving passes through the focus of a lens 7 due to vibration movement of a vibrating body 1. Therefore, signal is detected on the optical detector 8 in a series of pulses and output can be obtained and vibration of any vibrating body can be detected easily.

Title: Driving method of solid-state image pickup device
Inventor: MATSUDA YUUJI
IPC: H04N5/335
Filed: 1983-06-22
Abstract: PURPOSE:To eliminate an after-image phenomenon and to reduce a dark current and a smear, by supplying a negative voltage by shifting the level to a vertical transfer section in a horizontal blanking interval. CONSTITUTION:At the time of t=t1, the output pulse of a vertical shift register is applied to a vertical scanning pulse input line 3, and electric charge of an optical signal accumulated in a photodiode 1 is transferred to a vertical transmission line 5. At this time the electric potential of the vertical transmission line 5 is reduced by the level shifter amount of a negative voltage and the transfer from the photodiode 1 to the vertical transmission line 5 attains to switch mode. When t=t2, a connected part driving pulse is impressed after the negative voltage level is shifted and the charge of internal bias is sent to the vertical transmission line 5. At the time of t=t3, the optical signal charge and the internal bias charge are shifted below the next electrode. By repeating the above-mentioned operations, the electric potential of the vertical transmission line 5 is lowered and an MOS type FET2 is operated under the switch mode, and thus, the after-image is eliminated.

Abstract: PURPOSE:To realize high-precision power supply and high-efficiency operation, by providing a eliminating battery in parallel with the eliminating rectifier. CONSTITUTION:Eliminating rectifier 11 supplies electric power to communication devices while floating eliminating battery 12 connected in parallel to rectifier 11. In this case, when eliminating rectifier 11 is operating, battery 12 closes etiminating battery control electromagnetic switch 13 connected in series to eliminating battery 12 and is connected in parallel with eliminating rectifier 11. Since the battery has a very small internal impedance, compensation of the output voltage for instantaneous fluctuation of the load current and noise voltage absorption of the output circuit are performed by using this characteristic of the battery to connect the battery in parallel with eliminating rectifier 11. Battery 12 is separated or inserted after confirming that eliminating rectifier 11 stops or starts the operation to supply a current from the main battery and so on, thereby previnting transient fluctuation of the output voltage.

Filed: 1978-09-12
Abstract: PURPOSE: To obtain a scintillation camera which provides effective distortion corrections of a position calculation circuit even if incident radiation energy would disperse, by varying linearlity corresponding to the energy.  
     CONSTITUTION: The output of PMT is passed through linear amplifier 11 and all signals are added together by summing amplifier 12. The output of summing amplifier 12 is in proportion to a total of light through scintillation, i.e. energy of incident (γ) rays B. Therefore, the output wave crest value of summing amplifier 12 is adequately set by adjusting variable resistance 13, thereby making it possible to make corrections of distortion corresponding to the energy signal of incident (γ) rays B to PMT2. In this way, unbalance of the distortion corrections due to dispersion of energy when fixed non-linearlity is given at a fixed direct-current level never occurs and non-linearlity can be provided which maintains a stationary state against the dispersion of energy, so that extremely-excellent distortion corrections will be made.
