Abstract: PURPOSE:To attain to enhance printing quality by a thermal head by always keeping density constant even during long-time use, by providing a temp. sensor to the route of a thermal transfer ribbon and changing printing energy corresponding to the output from the temp. sensor. CONSTITUTION:A temp. sensor 11 is mounted to the lower part of the ribbon guide 17 for guiding a thermal transfer ribbon 8 to a printing head 15 in a closly contacted state. If the heat capacity of the ribbon guide 17 is preset so as to be made relatively small, the temp. sensor 11 can detect the temp. of the ribbon accurately within a short time. The temp. characteristic data of the ribbon is read from a memory to calculate a correction quantity to an energy reference value and an energy variable means 15, for example, a circuit for making a pulse width variable is driven to supply printing energy to a printing head 16. By this method, the pulse width to the ribbon having low temp. T1 at the mounting time of the ribbon, for example, immediately after the ribbon is issued from a cold dark place is increased in order to obtain the pulse width for imparting good printing density at reference temp. T0. Further, as the temp. T1 approaches reference temp. T0, said pulse width approaches a reference one. By this method, good printing density can be always held.

Title: Optical pad
Inventor: ONAKA SEIJI
IPC: H01L31/02
Filed: 1987-04-28
Abstract: PURPOSE:To contrive speeding up of a light beam by guiding the light beam as a guided wave to a photoelectric conversion part, while its light beam enters a light incident part which is formed at the surface of a semiconductor substrate where a photoelectric conversion element and an electric element are arranged. CONSTITUTION:A light beam entering a light incident part 2 which is formed at the surface of a semiconductor substrate 1 is guided as a guided wave to a photoelectric conversion element 5 which is formed at the substrate 1. In other words, the light beam enters the light incident part 2 having a size of tens-100mum and the light is guided by an optical waveguide 3 and then, the light enters the photoelectric conversion element 5 which is located at a part where elements are quite densely integrated. As interference does not occur between signals each other even through the optical waveguide 3 and electrical interconnections cross each other, the light incident part 2 can be arranged at any one of positions. Further, if a plurality of wave lengths of the light are used as the light beam, a mere part of the light incident part 2 is able to operate a different photoelectric conversion element 5 separately depending on the wave lengths of its light beam. This situation enables the whole integrated circuit to perform an operation at great speed.

Title: Time constant circuit with freely controllable time constant
Inventor: AIZAWA HIROKI
IPC: H03G7/00
Filed: 1981-07-06
Abstract: PURPOSE:To prevent the generation of a click noise, by connecting one-side terminals of resistances of a time constant circuit in common, and connecting the other-end terminals to a reference potential through a swith then changing the resistances and thus varying filter characteristics. CONSTITUTION:When a switch S is turned off, a transistor (TR) Q1 is also turned off, so the resistance for deciding on a time constant is only a resistance R1. When the switch S is turned on, the TRQ1 is turned on and the time constant is determined by resistances R1 and R2. At this time, one terminal of the resistance R2 is connected to the resistance R1 and the other terminal of the resistance R2 is applied with the same potential with the other terminal of the resistance R1, so that the potential of a signal line never varies. Therefore, when the noise reduction characteristics of a tape deck are changed over, the generation of a click noise by a filter circuit is prevented.

Title: Voltage comparison circuit
Inventor: NAMIKOSHI YASUMASA
IPC: H03K3/02
Filed: 1980-07-31
Abstract: PURPOSE:To achieve a voltage comparison circuit with a simple constitution and with high accuracy, by using a logical circuit element the threshold voltage of which is changed with the power supply voltage. CONSTITUTION:The 1st comparison signal is applied to an input terminal A of a logical element 1 and the 2nd comparison signal is applied to an input terminal B of a logical element 2. The output terminal C of the element 1 is connected to the input terminal of a voltage controlling circuit 3 and the result of comparison is outputted from an output terminal D of the element 2. When a comparison signal is inputted to input terminals A, B, the circuit 3 catches the output of the logical element 1 and controls the power supply voltage so that the threshold voltage of the logical element 1 can be equal to the comparison signal applied to the input terminal A. Since the same power supply voltage is applied to the logical elements 1, 2, the threshold voltage of the logical element 2 is the threshold voltage of the logical element 1, that is, the same voltage as the signal at the input terminal A.
