Abstract: PURPOSE:To make the refrigeration capacity correspond linearly to the load fluctuation to prevent intermittent on-off operation, by detecting the temperature of refrigerant that changes with load fluctuation, and automatically regulating the cold water flow rate of a cold water pump by an inverter so as to approach a refrigeration capacity corresponding to the load fluctuation. CONSTITUTION:An electric control circuit for a cold water pump 6 consists of a temperature sensor 7 that detects the temperature of refrigerant(cold brine), an inverter 8 that regulates the flow rate of cold water to an economizer 3, and a temperature control device 9 that regulates the inverter 8 according to the cold brine temperature detected by the temperature sensor 7. The temperature sensor 7 detects the cold brine temperature that changes with the load fluctuation. According to an increase or decrease in the cold brine temperature, that is, according to an increase or decrease in the load, the temperature control device 9 controls the inverter 8 to increase or reduce the rotation speed of the cold brine pump 6 so that the flow rate of the cold brine is regulated so as to approach a required capacity. When the flow rate of the cold brine to the economizer 3 is increased or reduced, the refrigeration capacity is increased or reduced correspondingly.

Title: Ice crusher
Inventor: HOSHINO SHOJI
IPC: F25C5/04
Filed: 1990-05-29
Abstract: PURPOSE:To make shaved ice in a short time by improving the efficiency of crushing, by a method wherein ice-lumps in a throwing case are crushed by a crushing edge, and these ice-flakes crushed enter a chamber formed between the throwing case and a cylindrical body, and crushed ice-flakes in this chamber are shaved by a slicing edge. CONSTITUTION:By the rotation of a rotary disk 35, a crushing edge 40 collides with ice-lumps in a cylindrical part 31a, and the ice-lumps are crushed one after the other, and are turned into small ice-flakes crushed. By centrifugal force caused by the rotation of a rotary disk 35, crushed ice-flakes are discharged outward through a gap L1 formed between the lower end of the cylindrical part 31a and the rotary disk 35. The crushed ice-flakes discharged from this gap L1 are coarse, and since the position of the lower end of a cylindrical part 32a is lower than that of the lower end of the cylindrical part 31a, the crushed ice-flakes collide with the cylindrical part 32a and enter the inside of a chamber 33. The crushed ice- flakes entering the inside of the chamber 33 are shaved by a slicing edge 41, and are turned into fine ice-flakes, and by the centrifugal force, the fine ice-flakes are discharged from a gap L2 formed between the lower end of the cylindrical 32a and the rotary disk 35 and are accumulated on the bottom part 30a of a vessel 30. Most of fine ice-flakes are either discharged from the gap L1 and enter the inside of the chamber 33, or discharged from the gap L2 without entering the inside of the chamber.

Title: Magnetic recording and reproducing device
Inventor: GOTOU KATSUHIKO
IPC: G11B5/027
Filed: 1983-08-01
Abstract: PURPOSE:To discriminate the PAL system or the NTSC system from the contents of a reproduced tape by counting the number of horizontal synchronizing signals during a video head changeover signal period. CONSTITUTION:The number of a horizontal synchronizing signals of a vertical synchronizing signal is 625/2 lines for the PAL system and 525/2 lines for the NTSC system. In using a proper numeral N being a middle value as a threshold level, the discrimination of PAL/NTSC is performed by counting the number of horizontal synchronizing signals. The reproduced horizontal synchronizing signal is counted by using a head SW signal (head changeover signal) 9. The horizontal synchronizing signal at a terminal 46 is inputted to a counter 41 via a waveform shaping circuit 40. The counter 41 counts the horizontal synchronizing signal by nearly a half period of the signal 9. The threshold level N is selected to a proper value and a trigger signal including respectively ''L'' and ''H'' in the output of an AND gate 42 is set by a count value being over the N or below the N. Thus, an output depending on the NTSC system or the PAL system is obtained at a terminal 20 by FF circuits 43, 44.

Abstract: PURPOSE:To always perform exposure control with high accuracy by selectively performing preliminary opening and closing actions according as a value from an element measuring the light amount of an object to be photographed which is the reference value of the preliminary opening and closing actions is outside or within a specified range. CONSTITUTION:When it is judged that the opening and closing actions of opening and closing members 14 and 15 become necessary for longer seconds than a specified value based on the value from the element measuring the light amount of the object to be photographed, the preliminary opening and closing actions are not performed and exposure opening and closing actions are performed based on the value from the element measuring the light amount of the object to be photographed. That is, whether non-exposure opening and closing actions are performed or not is judged based on the value from the element measuring the light amount of the object to be photographed which is the reference value of first non-exposure opening and closing actions. Thus, when the scanning characteristic, etc., of the opening and closing members of stop blades 14, 15, etc., are changed, fluctuation in control accuracy based on the change is prevented. The trouble in actual use does not occur, thereby controlling exposure amount with high accuracy.

IPC: H05B6/14
Filed: 1999-05-20
Abstract: PROBLEM TO BE SOLVED: To reduce waste of power and to improve energy-saving efficiency by providing the function of lessening power to a fixing device, and supplying minimum power, set by the power lessening function, by an induction heat inverter during standby time. SOLUTION: An induction heat(IH) fixing part generates a high frequency magnetic field by driving an inductance at a high frequency and an eddy current flows in a metal IH roller by the magnetic field, so that the temperature of the IH roller is increased to a temperature optimum for fixing. Such an image forming device starts up the IH roller to a temperature necessary for image formation as quickly as possible when a power source is turned on. Also, the device supplies necessary minimum power to a fixing roller from an IH inverter so that the temperature of the fixing roller does not drop as low as Ta deg.C during standby time T1 and is maintained at Tb deg.C which is higher than that. Therefore, start-up time T3 is shorter than conventional one, maximum supply time T2' at this time is also shorter than conventional T2, and an amount of power supply is decreased.
