Title: Image forming device
Inventor: YAMADA SHUJI
IPC: G03B27/34
Filed: 1988-06-25
Abstract: PURPOSE:To correctly detect the density of an original by moving a condenser lens moving upstream of a reference position to the reference position so that the condenser lens is not moved upstream of the reference position when a photosensor receives light from an original. CONSTITUTION:Before the photosensor 41 receives the light from the original 11, a moving means 36 moves the condenser lens 21 to the reference position without fail. Namely, even if the condenser lens 21 is moved upstream of the reference position to vary an original reading magnification, it is returned to the reference position without fail when the density of the original 11 is detected. As a result, with the condenser lens 21 located at the reference position, it does not shield light from the original 11 to the photosensor 41. Thus, the density of the original can be detected automatically and correctly all the time.

Title: Cdte radiation detecting element
Inventor: IWASE YOSHITOMO
IPC: H01L31/00
Filed: 1986-07-07
Abstract: PURPOSE:To decrease leakage current for increasing voltage load and to improve energy resolution in detection of radiation, by utilizing the interrelation between plane orientations of CdTe crystals and leakage current and forming electrodes on the {111} planes. CONSTITUTION:CeTe has two {111} planes which are called A and B planes. Cd atoms only are present on the A plane while Te atoms only are present on the B plane. A potential positive to the {111} B plane 3 is applied to the {111} A plane 2. Electrodes 4 are formed on the A plane 2 and on the B plane 3, whereby electronhole pairs are formed in a depletion layer 5. The electron- hole pairs are subjected to a bias voltage to provide ionization current. After direct current components are removed by a capacitor C, the ionization current is amplified and taken out as an output signal. Comparing this case in which the electrodes are formed on the {111} planes with a case in which electrodes are formed on any other plane, the {110} plane for example, leaked current is decreased more in the former case than in the latter case. Thus, a higher voltage can be loaded in the case of the {111} plane than in the case of the {110} plane. As a result, improved energy resolution can be obtained by forming the electrodes on the {111} planes.

Title: Brake locking device for automobile
Inventor: KATAMINE MIYUKI
IPC: B60T7/12
Filed: 1984-07-31
Abstract: PURPOSE:To prevent a creep phenomenon in an automatic car from occurring, by installing a brake locking device. CONSTITUTION:When a car stop is detected, a switch 15 comes into a state of being turned on to a normal contact, and a exciting coil 6 is energized with a continuous rating current whereby a moving iron core 7 is attracted toward a fixed iron core 4. After contact with the fixed iron core, a plunger 17 is kept at that position by dint of attraction due to a magnetic field of a permanent magnet 5. Thus, tip end 18 of the plunger 17 is closely fitted in an inner hole of packing 13. When a driver foot comes off a brake pedal, the packing 13 is pushed to the side of an inflow passage 8 by hydraulic pressure at the side of an outflow passage 9 and its escape passage 19 is also intercepted whereby braking pressure added in time of a car stop is left locked intact. With an accelerator pedal operated when one wants to start, the switch 15 comes ON to a revers contact and thereby diamagnetism is produced in the exciting coil 6 so that the attraction to the moving iron core by the permanent magnet 5 is thus released.
