Title: Refrigerator having air curtain-forming apparatus and method for controlling air curtain-forming operation
Inventor: SAI HEISHUN
IPC: F25D17/06
Filed: 1997-06-17
Abstract: PROBLEM TO BE SOLVED: To accurately form an air curtain free from malfunctioning of a door open/close sensor by starting an air fan to form an air curtain in the case when the opening of a door is sensed, and the temperature of a part adjacent to the door is sensed higher than a part isolated from the door. SOLUTION: A chilled air duct 33 is installed at an upper part of a cold storage chamber 42 and chilled air generated by an evaporator 49 is sent into the chilled air duct 33 by an air fan 31 to be discharged downward through a chilled air discharge port 35 for forming an air curtain shielding an opening of the cold storage chamber 42. In this process, the air fan 31 starts at the time when the opening of a door 45 of the cold storage chamber is sensed through a push switch 60 to form the air curtain. A microcomputer lets the air fan 31 start to form the air curtain when the temperature near the door 45 of the cold storage chamber as sensed by a door temperature sensor 63 is higher by a specified value than the temperature of the rear of the cold storage chamber 42 as sensed by a cooling chamber temperature sensor 65.

Title: Control valve device constituting differential circuit
Inventor: MUTOU YOSHITAKA
IPC: F15B13/00
Filed: 1982-09-15
Abstract: PURPOSE:To enable a fast movement of a cylinder to be performed under a condition in which no load is applied and further to enable the cylinder to be moved with a high thrust force when a load is applied by a method wherein a pilot passage is opened when a pressure at the rod side chamber is higher than a desired pressure and in turn the rod side chamber is not communicated with a supplying flow passage. CONSTITUTION:When a pressure in a rod side chamber 39 is reached to a desired pressure, a predetermined pressure sensing valve 64 is changed over to cause a pilot flow passage 41 to be communicated with a tank 68. As a result, a differential pressure is produced across a sensing orifice 43 and a pressure in the chamber 13 is higher than that of the spool chamber 12, so that a spool 7 rises against a spring 25 to cause a through-pass hole 31 to be communicated with a discharging flow passage 28 and an actuater flow passage 36 shows a tank pressure and a check valve 58 is returned back to its closed condition to close the communication between an actuater flow passage 36 and a supplying flow passage 29. Therefore, the returning oil in the rod side chamber 39 are returned back to a tank 50 and at the same time only the oil from the pump 51 is supplied to the bottom side chamber 38 and its thrusting force becomes higher and higher.

Filed: 1980-11-14
Abstract: PURPOSE:To improve frequency characteristics by preventing a magnetic recording medium from being saturated in a high frequency range, by providing a limiter circuit which operates when a high-frequency signal increases above a constant level. CONSTITUTION:A signal applied to an input terminal 1 is amplified by a recording amplifier 2 and then supplied to an equalizer amplifier 3. The high-frequency signal, passed through a high-pass filter 6 in a limiter circuit 5, of the output of the equalizer amplifier 3 is amplified by a level detecting amplifier 7 and converted by a rectifier 8 into a DC signal, which is amplified by a DC amplifier 9. As a result, the impedance of a variable impedance circuit 10 is varied by a DC signal level from the DC amplifier 9. When the high-frequency level of the input signal rises above some value, control is so exercised that the output of the qualizer amplifier 3 is constant. When the high-frequency level component is at a level below the value, the equalizer amplifier 3 has high-frequency emphasis characteristics.

Title: Nozzle for laser beam processing device
Inventor: TAKAHASHI HISASHI
IPC: B23K26/14
Filed: 1987-06-27
Abstract: PURPOSE:To increase the flow rate of an assist gas contributing to the splashing of the dross generated at the time of cutting by forming grooves which surround an assist gas ejection hole in overlap to the front end face of a nozzle so that the flow rate of the assist gas is suppressed. CONSTITUTION:The grooves 41 which surround the assist gas ejection hole 37 in overlap are formed to the front end face 39 of the nozzle 35 and throttling pieces 43 are formed between the respective grooves 41. These pieces, therefore, act as the resistance to the flow of the assist gas flowing out of spacings 47. The outflow of the assist gas from the spacings 47 is thereby suppressed to increase the flow rate of the assist gas to be ejected downward from a slit 45 of a work piece W. The assist gas is, therefore, efficiently used and the blowing away of the dross is more surely executed.

Filed: 1981-10-09
Abstract: PURPOSE:To guarantee the simultaneity and the synchronism, by saving data base before revision in time series and rewriting the data base immediately when new information is to be added and revised. CONSTITUTION:A data base is connected with a plurality of request sources RQ1-RQn which perform retrieval and revision entirely independently via a data base operation and controlling mechanism CM.

When the retrieval and revision take place in the same period, the retrieval goes back to the time series information not older than the time series information given to itself for the data base. Thus, the simultaneity and synchronism of the revision and retrieval can be ensured.
