Title: Moving bed type filtering device
Inventor: IWAI MITSURU
IPC: B01D29/62
Filed: 1982-09-21
Abstract: PURPOSE:To prevent in a low cost the water in a moving bed type filter from freezing, by driving a compressor by a signal of a temperature detector to circulate the water in an air-lift pipe, in a cylinder for regenerating and separating a filter medium, and in a filtering cylinder. CONSTITUTION:A temperature detector 19, interlocked with a compressor 20 used for transporting air, is attached to a small air-lift pipe 9. And for instance, when the outdoor temperature drops below a set temperature of the detector 19 in the night in a suspension state of the compressor 20, the detector 19 detects it to output a signal, which drives the compressor 20, transports air 7 to the pipe 9, and circulates the water in the pipe 9, in a cylinder 10 for regenerating and separating a filter medium, and in a filtering cylinder 1. As a result, the freezing of water is prevented because the compressor 20 is driven to supply the air to the pipe 9 for the purpose of generating a circulating flow before the water freezes in the pipe 9 and in a filter.

Title: Solid-state image pickup device
Inventor: HORII SAKAKI
IPC: H04N5/335
Filed: 1982-09-20
Abstract: PURPOSE:To prevent deterioration in picture quality even when is used to a still camera, by constituting one unit of charge transfer of vertical charge element rows of a solid-state image pickup device with structure units of more than three which form deep potential in the transferring direction. CONSTITUTION:Signal charges of two pieces of photoelectric conversion element are sent to two structure units I and III of one constituting unit of charge transfer composed of three structure units I -III. By a clock pulse added to a transfer gate electrode and vertical charge transfer element row, a deep potential is formed below a transfer electrode 14 and a charge 20 in the structure unit I is shifted to the structure unit II. The charge 20 in the structure unit II is shifted to the structure unit III after the charge 21 in the structure unit III is shifted to next structure unit. Since charges of charge transfer elements are successively sent to a horizontal reading register and read out, a still camera, by which the picture quality does not deteriorate, can be obtained by effectively reading out signals of the photoelectric conversion elements at a fixed time.

Title: Document reader
Inventor: NAKAMURA TETSUO
IPC: G06K9/00
Filed: 1995-06-07
Abstract: PURPOSE: To provide a document reader which does not perform unnecessary rerecognition. CONSTITUTION: A layout data confirmation and correction part 10a sets all the recognition flags of layout data ON when its confirmation and correction are performed for the 1st time and sets only a corrected part ON when not. A recognition part 5 recognizes only parts where recognition flags are ON. A recognition data confirmation and correction part 10b instructs the layout data confirmation and correction part 10a to conform and correct the layout data when the layout data need to be corrected after the recognition processing. Therefore, only parts of the layout data which are corrected are recognized for the 2nd and succeeding times and the parts which are already recognized correctly are not recognized.
Patent JP-S6320912-A (JP)
Title: Comparator circuit
Inventor: TANUMA JIRO
IPC: H03K3/0233
Filed: 1986-07-15
Abstract: PURPOSE:To prevent the occurrence of a phase lag and to improve the stability by providing a capacitor between an output terminal and a noninverting input terminal. CONSTITUTION:A slice level VR given to a noninverting input terminal of a comparator 1 based on a reference voltage is at first a prescribed value VTH decided by a resistance of resistors 2, 3. The moment an input voltage Vin exceeds the slice level VR being the prescribed value Vth, the level of an output voltage V0 of the comparator 1 is switched and inverted. As a result, a voltage having a time constant dicided with resistors 2-4 and a capacitor 8 is superimposed onto the slice level VR, and a microscopic hysteresis due to a differentiation wave (C) takes place. Since the hysteresis is attenuated with time, the level restores to the prescribed value Vth till the triangle wave input voltage Vin crosses the slice level VR and no phase deviation is caused.

Title: Pendulum type automatic recording hardness gage
Inventor: SATOU RIYOUICHI
IPC: G01N3/50
Filed: 1982-09-24
Abstract: PURPOSE:To measure the hardness of the surface of a thin film accurately, in a pendulum type automatic recording hardness gage, by arranging the tips of an objective terminal and a clamp supporting terminal on the same straight line, detecting the movement of a pendulum without contact, and performing continuous measuring and recording. CONSTITUTION:The movable part of a pendulum 10 is contacted with a material to be measured, which is a thin film of macromolecular material and the like through a steel ball objective terminal 12. The main body of the pendulum performs pendulum movement with the terminal as a supporting point. The material to be measured is supported on a heating plate 19 or a ceramic plate 20. The pendulum 10 on a clamp 21 is set on the material to be measured by turning a vertical calmp moving screw 28. The movement of the pendulum 10 is detected by a pickup 14 without contact through the movement of a metal plate 11 at the upper part of the pendulum. Thus the movement of the pendulum can be continuously measured and recorded without load, and the hardness of the material can be analyzed. Since the objective terminal 12 and a clamp supporting terminal 13 are located on the same straight line, the pendulum can be provided at the same point. Since the metal plate 11 always swings in the same area with respect to the pickup 14, measuring errors are decreased.
