Title: Formation of magnetic gap
Inventor: WASA KIYOTAKA
IPC: G11B5/23
Filed: 1984-01-23
Abstract: PURPOSE:To form a magnetic gap having a uniform gap length with good reproducibility and productivity by depositing a thin glass layer by a sputtering method, inserting conductive transparent glass into the light introducing hole of a base plate holder and monitoring the film thickness of the thin glass layer by using the intensity of the mutual interference of the light through the light introducing hole. CONSTITUTION:The generation of a film thickness distribution owing to the presence of a light introducing hole 22 of a base plate holder 21 is prevented by attaching conductive glass 23 into the hole 22 and the number of the base plate to be packed in the holder 21 is increased in the stage of forming a magnetic gap. A transparent glass plate of which the surface is covered with a transparent conductive film can be used as the conductive glass 23. He-Ne laser light is practicable as the ray 24 to be passed through the hole 22. The characteristic (b) shown in the figure is obtd. by attaching the glass 23 to the hole 22. The film thickness distribution near the light introducing hole is thoroughly eliminated by this invention.

Title: Battery checker of data back of camera
Inventor: KITAMURA YASUNORI
IPC: G03B17/02
Filed: 1980-01-31
Abstract: PURPOSE:To enable a small number of elements to confirm data recording and to make a battery check, by using a forward voltage drop across LED as a reference voltage for the battery check. CONSTITUTION:As switch 14 is closed through release operation, control circuit 15 sends a data recording signal to light display device 17 for a constant time and at the same time, a recording confirmation signal turns on transistor T6 via resistance 2 to turn on LED4. At this time, the potential at point (a) is equivalent to a forward voltage drop across LED4. When the potential difference between points (a) and (b) exceeds voltage VBE of T8, SCR13 is triggered to stop the operation of control circuit 15, so that the external display will disappear. Then, SCR13 turns on to store the information that the battery voltage is less than a prescribed value and the following data can not be recorded.

Title: Semiconductor memory device

IPC: G11C11/413
Filed: 1993-01-27
Abstract: PURPOSE:To eliminate supplying currents to word line drivers being non-selective states by selecting memory cells when the voltage on word lines connected to respective cells is in a low electric potential logic level. CONSTITUTION:A word line driver 4 selects a word line WLi according to the output of an address decoder and supplies two values of a logic level to the line WLi according to a selection/non-selection. That is, when it is in a stand-by state, it supplies the H level voltage VH of an ECL level at the time of the non-selection and a low level voltage VL of a pseudo ECL level at the time of selection to the line WLi. An SRAM 5 goes to the non-selective state when the voltage VH is impressed on the line WLi and to the selective state when the voltage VL is impressed on the line. Thus, the current comsumption in the driver 4 is reduced be cause the current is supplyed to some of word line driver 4 driving word lines connected to selected memory cells and is not supplyed to the majority of driver 4 of non-selection. The comsumption in all memories is reduced because the current comsumption occupies the majority of the current comsumption in memory chips.

Abstract: PURPOSE:To enhance the bearing resolution, by applying a specified delay time to pulses or wave reception signals to drive an ultrasonic vibrator by using a charge transfer element, and improving the precision of delay time to reduce the waveform distortion and loss. CONSTITUTION:When transmissing waves, pulsers P1... output driving pulses at high voltage enough to permit ultrasonic vibrators TR1 to TR32 arrayed in one row to radiate ultrasonic waves at the timing of control pulses from transmission control circuit 11, and driving pulses are applied to vibrators TR1....
