Title: Thermostatic automatic expansion valve
Inventor: ITAHANA TSUTOMU
IPC: F16K31/68
Filed: 1995-07-10
Abstract: PROBLEM TO BE SOLVED: To prevent a sensed temperature from being changed in response to a gaseous phase and a liquid phase of refrigerant by a method wherein a temperature-sensitive cylinder for use in sensing a temperature of refrigerant at an outlet of an evaporator is inserted into and installed at a refrigerant pipe at an outlet of the evaporator. SOLUTION: A temperature-sensitive cylinder 101 is inserted into and fixed to a refrigerant pipe 102 at an outlet of an evaporator. The temperature-sensitive cylinder 101 is inserted into the refrigerant pipe at a female threaded part 102a formed at one end of an inner side of the refrigerant pipe, a capillary tube 105 communicates with it and it is air-tightly pushed and held by a nut 103. A section near the fixing part of the nut 103 is thermally isolated from the surrounding air by a thermal insulator 104.  In this way, a thermal giving or acceptance between the surrounding air and the temperature-sensitive cylinder is shut off to cause a temperature of the temperature-sensitive cylinder to be governed only with a temperature of refrigerant flowing around the cylinder and in turn a gaseous phase section of wet refrigerant and a liquid phase section of wet refrigerant flowing in the refrigerant pipe show the same temperature from each other, so that under a state in which no giving or acceptance of heat is provided, a temperature variation of the temperature-sensitive cylinder caused by a difference in coefficients of heat transfer of the gas-liquid refrigerants is not produced.

Title: Driving method for five-phase pulse motor
Inventor: ANDO JUN
IPC: H02P8/00
Filed: 1991-06-17
Abstract: PURPOSE:To improve the characteristics immediately before stoppage by making a connection between full joints of a driving power supply with 100% ON duty at the time of driving and repeating control of load regulating joint, between 2 for four-phase excitation and 3 for five-phase excitation, with a set ON duty lower than 100%. CONSTITUTION:When a switching is made from four-phase excitation to five- phase excitation, joint of A and D phases is switched to positive pole under 50% load and thereby the joint of A and D phases goes (-) due to the electromotive force of A and D phases upon turn OFF. Consequently, a voltage 2Roio is applied on phase A and the potential across phase A goes (+) upon turn ON thus applying no voltage. At the time of five-phase excitation, switching speed is very high and the voltage of phase A increases a little and then decreases a little. The voltage of phase A increases gradually while repeating the increase and decrease operations and subsequently settles at a stable point. It settles under a current state where phase A = phase D = phase B = 0.8io. Consequently, smooth switching of excitation is carried out without causing damping of current.

Patent JP-H0927239-A (JP)
Title: Switch structure
Inventor: MUNEKATA ATSUSHI
IPC: H01H13/52
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To prevent malfunctioning of a switch even if a dial button is depressed at its edge by placing a surrounding buckling part which consists of two elastic bodies on a printed circuit board located around a support buckling part, and pointing the bottom of the button toward the support buckling part. SOLUTION: When a depressing force P is applied to the right end of a dial button 2, the side face of the button 2 comes into contact with a main-body upper cover 1 at a point C. When the depressing force P is removed, a frictional force works at the point C because of the elastic forces of a support buckling part 3 and a surrounding bucking part 9. In this case the elastic force of the buckling part 3 consists mainly of upward components. The elastic force of the buckling part 9 generates a couple according to the distance between the buckling part 3 and the surrounding support part 4 and tends to rotate the button 2 about the buckling part 3. Therefore the button 2 is rotated in the direction shown by the arrow X, and is restored to its initial state from a fitting hole 1a in the main body upper cover 1 as it resists the frictional force at the point C.
