Title: Formation of electrostatic latent image by multistylus
Inventor: KANDA HAJIME
IPC: G03G15/32
Filed: 1980-11-10
Abstract: PURPOSE:To decrease density irregularities and prevent the degradation in resolution by setting at least one of the voltages of the 1st and 2nd latent image formations lower than that of ''once-writing recording'' in twice writing recording. CONSTITUTION:At the time of twice writing, the Q output and Q' output of a flip-flop 7 inverts at every recording of one line, and at the time of twice writing, for example, in recording of the 1st line out of two lines, a switching circuit 62 is on and 600V voltage is applied between multistylus-segment electrodes 21, 22-, and in recording of the 2nd line, 500V voltage is applied. With 600V voltage, surface potential is about 80V, and recording density is in a saturation region of 1, but with 500V voltage, surface potential is about 30V, and recording density is as low as about 0.6. Hence, the decrease in resolution is low and developing irregularities are less.

Title: Semiconductor device and its manufacture
Inventor: TANDA TETSUO
IPC: H01L21/60
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To accurately align inner leads on a resin film to electrodes on a semiconductor chip by recognizing the positional deviations between the chip and inner leads by optically detecting alignment marks provided on the chip through through holes formed through the resin film.

Title: Radiation measuring instrument
Inventor: MAKINO SHUNICHIRO
IPC: G01T1/15
Filed: 1993-06-29
Abstract: PURPOSE:To improve the accuracy of a radiation measuring instrument by detecting the output variation of an error amplifier at the time of converting input charges into a voltage after integration and feeding back the variation to an integrator and, at the same time, eliminating discharge from the integrator by holding the function of the integrator in a hold circuit and making a feeding back time constant variable. CONSTITUTION:When an error amplifier 32 is actuated, feedback is started so that the level of the output signal 5 of an integrator 13 can become a GND level and, even when a leakage current exists in a radiation detector, the current is not integrated, but canceled. During the output of a control signal 34, on the other hand, the output voltage 37 of a sample hold circuit 33 does not change even when the input to the integrator 13 changes and the amplifier 32 detects the change and outputs a cancel signal (the amplifier 32 responses during the period of integration even if the response is slow). Then the integrator 13 integrates the variation of the input to the integrator 13, namely, the electric signal 2 of the radiation detector and outputs the signal 5. Since the sample hole circuit 33 works during the integration, the integration can be performed accurately.

Title: Quantum resistance standard
Inventor: MIURA AKIRA
IPC: G01R27/02
Filed: 1987-06-26
Abstract: PURPOSE:To obtain a micro quantum resistance standard by providing the electrodes for measuring the hole effect on the surface of a superconductor layer so that they are orthogonal. CONSTITUTION:On a substrate 1, a superconductor layer 2 is formed with a thickness which is thinner than the London penetration length but allows the penetration of a magnetic vector. Electrodes 3-6 for measuring the hole effect are provided on the surface of the superconductor layer so that they are orthogonal. An insulating layer 7 is formed on the surface of the superconductor layer 2 so that the electrodes 3-6 are exposed. With this, a device D operating as a quantum resistance standard is constructed. The device D is cooled until it becomes superconductive. And the magnetic field is strengthen while a current Ic is made to flow in the device D. Since the superconducting state is accomplished at a high cooling temperature and the scattering mechanism does not act on the superconducting particles for their motion in a two-dimensional plane, the quantization hole effect can be obtained by a relatively weak magnetic field. For this, a micro quantum resistance standard can be formed.
