Title: Generator for pulse width modulation signal
Inventor: HONDA TAKAYOSHI
IPC: H02P25/06
Filed: 1998-09-30
Abstract: PROBLEM TO BE SOLVED: To provide a generator for generating a pulse width modulation(PWM) signal which can vary the duty cycle of the PWM signal with a good responsibility without disturbing the period of the PWM signal. SOLUTION: Based on an ON-time data TON calculated every predetermined time by a CPU and stored in a RAM which represents the count value corresponding to a high-level time per one cycle (CYCL) of a PWM signal, a circuit for generating and outputting the PWM signal for driving an electrical load clocks repeatedly by a down-counter the half-period time of the PWM signal, and whenever the count value CNT of the down-counter becomes zero, the circuit inverts a flag PFLG1 and reads the ON-time data TON from the RAM. Then, when during the term of the flag PFLG1 being high the foregoing count value CNT becomes the half value of the ON-time data TON, the circuit makes high the PWM signal.  Further, when during the term of the flag PFLG1 being low the foregoing count value CNT becomes the half value of the value obtained by subtracting the ON-time data TON from the value corresponding to the one cycle time of the PWM signal, the circuit makes low the PWM signal.

Title: Manufacture of heat pipe
Inventor: MOCHIZUKI MASATAKA
IPC: F28D15/02
Filed: 1985-12-12
Abstract: PURPOSE:To prevent overheating and the phenomenon of bumping by setting up a temperature difference in a heat pipe so that the temperature on its upper side is higher than the lower side and heating the body of the heat pipe. CONSTITUTION:In order to exhaust non-condensating gases such as air from the inside of a pipe body 1 the pipe body 1 filled almost fully by a working fluid 3 is set up upright with its nozzle 2 positioned on the upper side, and in this state of the pipe then upper section is heated by a heater 4 and the lower section is cooled. In other words the heating is for raising the temperature of the upper section to set up a temperature difference in the up-and-down direction. As a result, evaporation of the working fluid 3 occurs on the upper side, and by the vapor the non-condensating gases in the pipe body 1 are exhausted. In this case, because the working fluid 3 is heated from the upper side, there is no bumping. When the level of the working fluid goes down to the cooling section 5, no vapor of the working fluid 3 is produced, and it is, therefore, possible to set automatically the final volume of the working fluid 3 to be evaporated down to the cooling section 5.
