Title: Synchronizing circuit for synchronous motor
Inventor: IGAWA HIROSHI
IPC: H02P1/52
Filed: 1984-10-01
Abstract: PURPOSE:To effectively synchronize a synchronous motor by inputting the voltage of a starter to an automatic synchronizer through a filter for delaying in the same phase as a phase delay by a synchronizing operation. CONSTITUTION:When a synchronous motor 11A is started, breakers 13A, 5, 3 are closed, the output voltage and the frequency of a variable voltage variable frequency inverter 4 are sequentially enhanced to synchronously start the motor 11A. An automatic voltage balancer 8 and an automatic speed synchronizer 9 control the inverter 5 so that the output voltage and frequency of the inverter 4 coincide with those of a system power source 1. On the other hand, the output of the inverter 4 is applied to a filter 12 for delaying in the same phase as the phase delay by the deceleration of the motor 11A at the synchronizing time, and an automatic synchronizer 7 closes a breaker 10A when the output of the filter 12 coincides with the output of the power source 1 to connect the motor 11A with the power source 1.

Title: Ink jet recording apparatus
Inventor: FUJII MASAHIKO
IPC: B41J2/05
Filed: 1995-08-10
Abstract: PROBLEM TO BE SOLVED: To improve print quality with an appropriate amount of ink drops ejected while making electric driving conditions the same for nozzles for an ink jet recording apparatus with which ink drops in different colors or different densities are ejected. SOLUTION: A heating area 25 and a low resistance area 26 are formed by laminating a polycrystalline silicone layer serving as a heating resistance body on an Si substrate. The size of the heating area 25 is determined in accordance with property of ink ejected from a corresponding nozzle. Thereby, the amount of ink drops ejected from the nozzle becomes appropriate and quality of print can be improved. The heating area is so formed that resistance value at the heating area becomes larger as the size of the heating area 25 becomes smaller. Thereby, the amount of energy per unit area becomes equal, and driving by the same driving pulse becomes possible.

IPC: F25B49/04
Filed: 1989-08-07
Abstract: PURPOSE:To avoid shut-down of an absorption refrigerating machine caused by stoppage of a high temperature regenerator by providing a controller which obtains a predictive temperature of the high temperature regenerator from the load factor and the inlet temperature of cooling water, compares the predictive temperature with the temperature of the high temperature regenerator, and outputs a signal to bring an alarm in action. CONSTITUTION:A temperature detector 32 detects the cooling water outlet temperature of an evaporator 4. A temperature detector 33 detects the cooling water inlet temperature, and a temperature detector 34 detects the temperature of a high temperature regenerator 1. A controller 35 receives signals from the temperature detectors 31 and 32 and calculates a load factor from the temperature difference between the inlet and outlet of cooling water and the temperature difference between the inlet and outlet of cooling water at the 100% load. Then, the controller obtains a predictive regeneration temperature of the high temperature regenerator 1 from the load factor and the cooling water inlet temperature, and compares the predictive regeneration temperature with the regeneration temperature detected by the temperature detector 34. And when the temperature of the high temperature regenerator 1 is higher than the predictive regeneration temperature by a specified value, a temperature alarm 36 is put in action to output an abnormal indication.
