Title: Electric hot water heater
Inventor: FUKUTO MASAAKI
IPC: F24H9/00
Filed: 1988-10-31
Abstract: PURPOSE:To make a drum satisfactory in weld quality and strength at negative pressure by radially expanding a shell plate at either or both of the upper and lower ends and by fitting the radially expanded parts on the respective rims of the upper and lower end plates and joining them by welding. CONSTITUTION:An electric heater for hot water has a drum 13 formed of an upper end plate 14, a lower end plate 15, and a shell plate 16 with the end plates fitted in the shell plate at the upper and lower ends. The upper end of the shell plate 16 is formed of a first tapering part 23, a second tapering part 24, and a radially expanded part 25. The outer circumferential surface 26 at the rim of the upper end plate 14 is inserted and fitted down the upper end part (the second tapering part 24 and the radially expanded part 25) of the shell plate 16 with the edge 27 of the end plate 14 pressed against the inner surface of the first tapering part 23 and their joint 28 welded from within the drum. The lower end of the shell plate 16 is formed of a tapering part 29 and a radially expanded part 30. The edge 31 of the radially expanded part 30 is pressed against the outer surface 32 of a tapering part of the lower end plate 15 and the joint 33 is welded from the outside of the drum. Even if drum parts show a lack of uniformity in the accuracy of forming, dimensional accuracy and circularity are secured for the brims of the upper and the lower end plates so that improvements can be achieved in weld quality and in strength at negative pressure.

Title: Comparator
Inventor: TSUKADA TOSHIRO
IPC: H03M1/12
Filed: 1984-12-26
Abstract: PURPOSE:To execute a high speed comparing action with a simple constitution by arranging plural comparator circuits composed of a capacitor for sample- holding plural voltages and a means for amplifying the variable voltage of the capacitor in parallel and latching the output of a comparing and amplifying circuit. CONSTITUTION:In terms of the A/D converter of four bits, high order two bits and low order two bits are alternately converted to execute the four-bit A/D conversion. First an input voltage Vin and the high order two bits Du are decided. Successively any one of four switch groups 11 corresponding to the Du is selected, and the comparison of the low order two bits is executed in synchronizing with a clock phiSL. Since comparators 20 and 10 use a sample- type comparator and a non-sample-type one, respectively, the overall converting action can be executed in cycle of high speed clocks phiSU and phiSL. Since the comparator 20 samples a clock with the input voltage V1 having a small inner resistance, the high speed can be sufficiently held.

Title: Far infrared ray emitting stomatal physical therapy device
Inventor: WAKAIDA KAZUO
IPC: A61H39/06
Filed: 1988-10-31
Abstract: PURPOSE:To apply mild stimulation to subcutaneous tissue, especially, a peripheral nerve by a method wherein the leading end part of a grip emitting far infrared rays is brought into contact with or opposed to a human body while a proper temp. state is held. CONSTITUTION:A switch 9 is turned ON to heat a ceramic substrate 5 and far infrared rays are emitted forwardly. When the temp. of the ceramic substrate 5 reaches set upper limit temp., for example, 50 deg.C, the supply of a current is controlled by a change in the electric resistance of ceramic itself and the temp. of said substrate is kept. The wavelength of the electromagnetic wave generated from the ceramics substrate 5 becomes that of infrared rays of 100mum or less by passing the electromagnetic wave through the microstructural polycrystal texture of the substrate but, since far infrared rays in a wavelength region of 4mum or more are good in the resonance absorption with an org. molecule, mild radiant heat can be sensed by a human body and has the penetration properties to the deep part of the human body.

Title: Information reader for optical disk
Inventor: YAMAZAKI SEIICHI
IPC: G11B7/085
Filed: 1990-10-12
Abstract: PURPOSE:To prevent the fluctuation of a DC level and to smoothly execute searching operation by detecting the boundary between a recorded area and an unrecorded area based upon a peak value detecting signal, discharging electric charge accumulated in a coupling capacitor. CONSTITUTION:When an optical pickup approaches the boundary between a recorded area AW and an unrecorded area NW at the time of searching operation, an RF component is not included in an RF signal A in the succeeding area NW. Thereby, a single amplitude waveform is formed, a difference between a peak value VP and a bottom value VB disappears, the output of a peak value detecting circuit 5 comes to approximately equal to that of a bottom value detecting circuit 6, and a comparator 7 outputs a reset pulse E. Thereby, a reset circuit discharges the charge accumulated in the capacitor 2 and a corrected detection signal D is obtained. Consequently, a difference between the reference levels of the areas AW, NE is not generated and an on-track detection signal C to be the output of a comparator 4 comes to an accurate track counting pulse, the generation of miscounting can be prevented, and smooth searching operation can be executed.

Title: Optical information recording medium
Inventor: KATSUHARA WATARU
IPC: G11B27/10
Filed: 1991-10-22
Abstract: PURPOSE:To easily perform a high-density recording operation by a method wherein a most significant bit in the recording region of a track No. allocated to an IC part is allocated as the most significant bit of a sector number. CONSTITUTION:A piece of ID information is read out by using an optical head. Whether a piece of data in the piece of ID information has been read out correctly or not is checked by using a CRC. When it is not read out correctly, an error is processed. When it is judged that the piece of ID information has been read out correctly, the logical product of first two bytes multiplied by (7FFFH)16 in the piece of ID information is operated. This result is shifted by one bit to the direction of one significant bit; the logical product of a piece of data in a third byte, from the head, multiplied by (3FF)16 is operated. The logical products of these processing operations are operated; this result is retained as a sector number.

Filed: 1991-10-22
Abstract: PURPOSE:To reduce a drain disturbance, which is generated in a non-selection cell at the time of writing of information, by a method wherein the relation between the length and depth of a second impurity region, with which a bit line is electrically connected, is specified. CONSTITUTION:Let the length from the lower part of the side end part of a floating gate 4 along the channel length be A and the depth from the surface of a P-type silicon semiconductor substrate 1 be B. An n<+> drain region 10 is so formed as to satisfy the condition of B/A>=2. In such a way, the area of a region where the region 10 overlaps with the gate 4 is reduced, whereby the area of a region, where a drain disturbance is caused, can be also reduced. Thereby, the drain disturbance, which is generated in an unselected cell at the time of writing of information in a flash EEPROM, can be effectively reduced.
