Title: Speed detector for rotating machine
Inventor: SUGIZAKI IWAO
IPC: G01P3/489
Filed: 1990-08-02
Abstract: PURPOSE:To obtain a rotating machine speed detector with high accuracy by counting the intervals of speed detection pulse for a rotating machine with a high speed frequency. CONSTITUTION:A speed detector for a rotating machine is constituted with a counter 1 to count the pulse intervals f1, f2...fn of the speed detection pulse fv for a rotating machine with a high speed frequency fx, a memory 2 to memorise the count value, and a CPU 3 to control the counter 1 and the memory 2 and to apply a determined calculation to the count value. Supposing the divisions of the speed detector to be 4, the measurement of the pulse intervals f1, f2...f4 in the counter 1 with the high speed frequency fx makes the count at a determined time Talpha after the generation of fv signal to be f1(m)=5, f2(m)=4, f3(m)=3, f4(m)=7. The speed data corresponding to the sampling number 2 in this case is equal to speed data f1(m)+f2(m)+f3(m)+f4(m)=19 of the sampling number 1, and therefore, the effect of division error in the speed detector is rejected.

Title: Temperature control device for light source
Inventor: SAKAI YOSHIHIRO
IPC: H01J61/52
Filed: 1984-10-01
Abstract: PURPOSE:To make it possible to stably show a disired temperature control effect while simplifying the construction and surely preventing excessive temperature rise by controlling power supply to a heating member through a switching element changing according to a quantity of heat. CONSTITUTION:While a vacuum evaporation heater 4 is not conducted, the tip 7a of a bimetall 7 is contacted with the surface of the heater 4 electrically conductively. And when a switch 6 is closed to supply power, the heater 4 is conducted through the bimetal 7 for heating a fluorescent lamp 1. When the temperature of the heater exceeds a prescribed value, the bimetal 7 is transformed for separating its tip projection 7a from the surface of the heater 4 while the conduction to the heater 4 is stopped. Thereby, the bimetal 7 is cooled for conducting again the heater 4. By repeating said operation the temperature of the heater 4 and the internal temperature of a fluorescent lamp 1 are maintained within a proper range for obtaining a stable optical output while preventing an accident due to excessive rise of temperature of the heater 4.

IPC: B41J35/16
Filed: 1983-10-31
Abstract: PURPOSE:To improve the print processing speed by differentiating the capacity of buffer memories corresponding to printing sections by one printing line to enable a multicolor printing simply by moving the print head only once. CONSTITUTION:In an ink ribbon 5, color bands 5a-5d are arranged each with the width D at the right angle to the printing direction. So, after the color band 5a is transferred thermally, a recording paper is fed by the width D of the subsequent printing line portion for the heat transfer of the color band 5b. Driver circuits 15a-15d controls the heat generation of heat generating elements 4 in corresponding printing sections 3a-3d based on a color data memorized in buffer memories 11-14. For example, in the buffer memory 13, the color data of the color band 5c for one line is first memorized in a memory area 13c, transferred to memory areas 13b and 13a sequentially each time a recording paper is fed by one line and read out with a CPU7. As a result, the printing operation for the third line thermally transfers the color bands 5c-5a at respective specified printing positions at the first, second and third lines.

For example, when a voltage waveform (b) is used, a driving signal is cut at a level A, a small ink droplet is generated. When a voltage waveform (c) is used, the signal is cut at a level B, and a large ink droplet is formed.
