Title: Thermal head
Inventor: ENDO TETSUO
IPC: B41J2/345
Filed: 1986-05-10
Abstract: PURPOSE:To prevent a voltage applied to each heat generating resistor from varying due to different voltage drops and prevent printing quality from being deteriorated, by a wiring construction wherein the wiring resistance of a common electrode between adjacent ones of heat generating resistors and that between adjacent ones of driving elements are substantially equivalent, and the sum of the wiring resistance from one power source terminal to the heat generating resistor and the wiring resistance from the other power source terminal to the driving element is substantially equal for each of the heat generating resistors. CONSTITUTION:Wiring resistances r1, r2, r3...r6 of a common electrode 1 between each adjacent pair of heat generating resistors R1, R2, R3...R7 and wiring resistances r11, r12, r13...r16 of a common electrode 2 between each adjacent pair of driving elements T1, T2, T3...T7 are equal, because the widths of the common electrodes 1, 2, are equal to each other and the heat generating resistors R are arranged at regular intervals. All of total wiring resistances A1, A2, A3...A7 for the heat generating resistors R1, R2, R3...R7 from one power source terminal 1a to the other power source terminal 2a are ra + 6r + rb. As a result, the voltage drop due to the wiring resistance is substantially equal for each of the heat generating resistors R1, R2, R3...R7, and accordingly, the voltage applied to the heat generating resistor is substantially equal for each of the heat generating resistors.

Title: Input device for analog signal
Inventor: ONDA TOSHIKAZU
IPC: G06F3/05
Filed: 1982-06-22
Abstract: PURPOSE:To simplify a circuit and to speed up comparing and judging operations, by using a pulse width corresponding to an analog signal for comparing the analog signals with each other. CONSTITUTION:When the analog signals Vs and Vp are compared with each other, the signal Vs is passed through a preamplifier 9, VF converting circuit 1, insulating device 2, an interval timer 3 to input a measured value ts to a measured value input part 41. The measured value ts is supplied to a correction part 42 to find pulse width tps, which is stored in a set value storage part 43. The analog signal Vp, on the other hand, is passed through a preamplifier 9a, VF converting circuit 1a, insulating device 2a, and interval timer 3a to input a measured value tp to the input part 41 and a comparative decision part 44 compares the measured value tp with a set value tps; and the signal Vp is fetched after the decision and the same processing is carried out successively. Thus, while one analog signal is used as a criterion, the other analog signal is read in every period to make a comparative decision, so the need for arithmetic is eliminated and the period is shortened.

Title: Semiconductor device
Inventor: SAKAI TOSHIAKI
IPC: H01L23/20
Filed: 1985-05-20
Abstract: PURPOSE:To prevent the effect of alpha rays and to improve the reliability of a semiconductor memory device and the like, by sealing a specified gas in a package, in which a semiconductor chip, wherein an integrated circuit is formed, is built in. CONSTITUTION:A recess part 17 is formed by an inner wall 11a of a main body 11 of a package and a stage 16 in this semiconductor device 10. A gas, whose amount of electrons is large and pressure is large, is sealed in the recess part 17. The recess is tightly sealed by a cap 13. In this device, since the gas, whose atomic weight is large, is sealed, the range of alpha rays in the gas becomes short. Since pressure is applied to the gas, the range is further shortened, and the alpha rays are hard to reach a chip 12. As a result, even if the alpha rays do not loose energy completely, the energy is extremely decreased, and the data held by the chip 12 is not inverted.

Title: Optical fiber for detecting liquid and cable including it
Inventor: INAGAKI TOMONORI
IPC: G01M3/38
Filed: 1997-04-25
Abstract: PROBLEM TO BE SOLVED: To detect the intrusion length of liquid into a long region by arranging a liquid absorbing resin around a core and providing an air gap between the liquid absorbing resin and the outer circumferential surface of the core. SOLUTION: With regard to the intrusion detection optical fiber 10 a core 12 coated with a clad 20. The core 12 is composed of an optical resin, e.g. quartz glass, and the clad 20 is composed of a basic material 22 mixed with a massive water absorbing resin 24. The basic material 22 is composed of an optical resin, e.g. quartz glass, similarly to the core 12 and the refractive index thereof is set lower than that of the core 12 so that a light propagating through the core 12 is totally reflected on the interface between the core 12 and the basic material 22 of the clad 20. When water intrudes at any point of the intrusion detection optical fiber 10, the water absorbing resin 24 absorbs the water to be swelled and an air gap 30 is filled.  Since a light propagating through the core 12 leaks at the interface between the core 12 and the water absorbing resin 24, leakage can be detected for a long region by measuring the transmission loss of light due to the optical fiber 10.

Title: Character generating device
Inventor: WAKIZAKA SHINJI
IPC: G06T11/20
Filed: 1993-05-11
Abstract: PURPOSE:To obtain a character generating device which is suitable to power consumption reduction of a system and LSI-implementation by composing the device of plural modules and stopping the functions of modules which do not operate in accordance with modes. CONSTITUTION:A module 1 (13) is a vector block and a module 2 (14) is a raster block. For example, when mode information written in a mode register 11 indicates a mode wherein the process of the vector block is not performed for outline font data inputted to the character generating device, a block supply control circuit 12 does not supply a clock CLK1 to the vector block. A necessary irreducible clock, however, is supplied for transfer from a font input FIFO to an FIFO through the vector block. A mode wherein the process of the raster block is not performed is the same. Thus, the functions of the modules 13 and 14 which do not operate to perform conversion specified by the modes are stopped.
