Title: Form of notch reducing fluid force of spool valve
Inventor: MATSUMURA SHIZUO
IPC: F16K11/07
Filed: 1980-05-08
Abstract: PURPOSE: To reduce fluid force functioning to a spool in cases of small flow rate and large flow rate by inclining a bosom surface of a notch and forming the notch in a slot-shaped groove.  
     CONSTITUTION: When small flow rate flows into a notch (a), oil also flows into the deepened bosom side because a bosom surface 5 is inclined and a bosom of the notch (a) is deepened, and fluid force can be reduced when an angle of inflow θ 1  increases. The fluid force is apt to increase with the augmentation of the opening of a  land circumferential surface opening section 3, but oil is focused when a fluid passes through the notch a because the notch (a) is formed in a slot-shaped groove, and  the considerable velocity of flow V 2  is obtained. When an angle of inclination of a  guide surface 4 is selected properly, fluid force F 1  generated by inflow oil and fluid  force F 2  generated by outflow oil are offset each other, and the fluid force functioning to a spool is reduced.

Abstract: PURPOSE:To provide a level converting function to an input and output circuit, by providing a level converter and a clocked inverter. CONSTITUTION:In writing data to an RAM, when a write signal inversion b' is at L level and a data signal on a data bus DBS is at L level, a charge of a capacitor 6 of a level conversion circuit 41b is discharged via MOSFETs 5B and 5C, and the potential at point A is at H level, which is almost 0V. When a write control signal b goes to H level, an H level signal at point A is applied to an input and output terminal I/O of the RAM via a write control circuit 41a. When a signal on the bus DBS is at H level, the level at the point A is held to L level of a power supply Vss2 with the capacitor 6 and a signal of L level is applied to the terminal I/O. Next, when a readout control signal a goes to H level, a clocked inverter circuit 41c is operative and a signal at the terminal I/O is applied to the bus DBS.

IPC: F25D19/00
Filed: 1994-03-30
Abstract: PURPOSE:To decrease a load of a compressor at a time of a pull-down by making a pressure of a high pressure side cycle small. CONSTITUTION:A large diameter section 17 having a larger diameter than that of a coolant flow path is connected, in the coolant flow path of an evaporation pipe 16 and a wire condenser 19. This large diameter section 17 has a hollow state and enlarges a volume of a high pressure cycle from a compressor 14 to an evaporator 23. With this, as a heat-exchanging is executed between a high temperature and high pressure coolant discharged from the compressor 14 and an outside air, and even a function making a pressure of the coolant decrease, exists, a pressure of a high pressure side cycle becomes small, and a load of the compressor at a time of a pull-down is reduced.

Title: Phase locked loop
Inventor: KIKUKAWA HIROHISA
IPC: H03L7/093
Filed: 1997-03-17
Abstract: PROBLEM TO BE SOLVED: To quickly and stably shift a frequency. SOLUTION: Frequencies of outputs of a reference signal source 1 and a voltage controlled oscillation circuit 3 are divided by frequency division circuits 2 and 4 respectively. A phase comparison circuit 5 outputs an error signal corresponding to the phase difference between these signals. A window signal is outputted from a window generator circuit 9; and if the error signal is not within its pulse width, a level generator circuit 10 generates a boost voltage close to the control voltage value of the voltage controlled oscillation circuit 3 which is used to generate an objective frequency. A low pass filter circuit 7 receives the output of a charge pump circuit 6 and the boost voltage and is charged, and the control voltage quickly rises to a target value without rising to an excessive value. Thus, undershoot and overshoot are suppressed to quickly stably shift the frequency.
