Title: A/d converter with clamping circuit
Inventor: KOIKE YUKIO
IPC: H03M1/18
Filed: 1987-07-07
Abstract: PURPOSE:To reduce an error in A/D conversion without increasing an area or complicating a circuit, by measuring the value of digital output in a period while a clamp signal is set at a level HI, and varying clamp reference potential supplied to a clamping circuit by the value. CONSTITUTION:When the clamp signal goes to the level HI, switches SW109 and SW111 are turned ON, and a switch SW110 is turned OFF, and the output of a buffer amplifier A106 is operated so as to be conformed with the clamp reference voltage 100 impressed on the non-inversion input of an OP-AMP108. At this time, a reference voltage which offsets -(V10108 +V10113) is selected, and it is supplied to the non-inversion input of the OP-AMP108 as the clamp reference voltage 100. Therefore, no conversion error is generated even when the OP-AMP108 or a comparator group 113 is provided with a large offset voltage. Accordingly, it is possible to make the area or the increase of the number of elements to obtain a relative accuracy required to realize a low offset in an on-going device, or the complexity of the circuit unnecessary.

Further, since nothing obstructing the illumination light exists between the light transmission plate 3 and the LCD 2, the illumination of the whole part of the display contents is performed. Further, the LCD 2 is decorated with various contents by the exchangeable image information plate 5.

Title: Control of optical information reproducer
Inventor: ISAKA HARUO
IPC: G11B7/09
Filed: 1984-08-16
Abstract: PURPOSE:To perform quick and effective control for changes in reflectance and transmissivity due to injuries of a recording carrier, by modulating the light quantity of a light source with a prescribed modulation frequency and controlling the DC bias of a position control means so as to minimize the modulation frequency component of a light source modulating means among the error signals. CONSTITUTION:A changeover switch 23 is switched to select a secondary error signal. Then an offset control means 9 sets the sum of the 1st offset component which varies by the change of light quantity and the 2nd offset component which has no variation with the change of light quantity at zero. The relative position error is set at the minimum level. Under such conditions, the light quantity of a light source 3 is modulated by a light source modulation means 21 with a prescribed frequency. Then the modulation component contained in the error signal is detected by a modulation component detecting means 22 and set at zero with control of a balance control means 7. When the relative position error is minimized with said control, the error signal contains no 1st offset component. Then the switch 23 is switched again to detect the modulation component contained in the error signal through the means 22. Then the means 9 is controlled to set the modulation component at zero. Thus the 2nd offset component is also set at zero.

Title: Water heater
Inventor: SEDORITSUKU ISURAERUSON
IPC: F24H1/10
Filed: 1988-07-08
Abstract: PURPOSE: To compensate a wide conductivity region of water, by providing an electrode dipped in water to be heated, a detector for detecting characteristics exhibiting the degree of heating action, and switch means which is switched to selection of a heater in response to detection characteristics. CONSTITUTION: All electrodes 11, 12 are mounted closely between a bottom 20 of a box and a cover 21. The electrode 11 is inserted into a wall 22, and a neutral wire 12 is connected with a wall 23. This constructs a zig-zag path for permitting the water to be heated with a current to pass through an apparatus. The current flows from an active conductor to the neutral conductor when the water flows through the path. Since these conductors are flush with each other, effective electrical heating areas of these conductors are determined by their lengths. As a result, water conductivity can be automatically changed by automatically changing the all electrical heating areas of the water exposed to the current controlled by an electronic device or a switching device.
