Title: Valve
Inventor: YONEKUBO HIROAKI
IPC: G01F1/26
Filed: 1979-01-17
Abstract: PURPOSE: To prevent self-excited vibration from occurring in a valve body, by tapering that portion of the valve body which is opposed to a valve seat, and providing the tapered portion of the valve body with at least three slits at regular intervals, whereby the magnitude of force received by each part of the valve body can be equalized.  
     CONSTITUTION: A valve body 12 is formed in the shape of a flange having stems 13, 14 on both sides thereof. The valve body 12 is diverged toward the downstream side and has a conical outer surface 15 contacting an open end portion of a movable valve seat 8. Accordingly, even when the valve stems 13, 14 are oscillated to cause the valve body 12 to be inclined, the valve body 12 constantly receives a fluid pressure in a balanced manner. The valve body 12 is provided with at least three regularly-spaced slits 16, 16', 16" for use in determining a minor flow rate, so that the valve body 12 receives the same magnitude of force all over the outer surface thereof. Namely, a fluid pressure is always exerted on the valve body 12 uniformly. Even when the valve body 12 is removed from the movable valve seat 8 due to variation in flow rate of the fluid, a gap between the valve body 12 and valve seat 8 is gradually increased so that a sudder change in drag coefficient can be prevented. The valve body is also affected little by the dynamic pressure. Thus, self- excited vibration can be prevented from occurring in the valve body.

Title: Method for controlling automatic transmission
Inventor: NAKAMURA HIROYA
IPC: F16H61/04
Filed: 1986-01-13
Abstract: PURPOSE:To make the operating timing of a frictional engaging element proper by setting the output signal from an electronic controlling device for one hydraulic servo mechanism among plural frictional engaging elements, later by a defined time than an output signal to another. CONSTITUTION:An automatic transmission 1 engages or releases clutches, etc. which are frictional engaging elements, by means of a hydraulic servo mechanism to carry out shifting between each of transmission stages. A transmission oil pressure controlling device 32 which carries out the control of said shifting is controlled by solenoids No.1-No.3 which are ON-OFF controlled by a computer 33. Since the quantity of remaining oil which is mixed into the hydraulic servo mechanism is different between when idling under released condition and when stopping, it takes longer time for a clutch to be engaged after through idling than without through idling. Accordingly, an output signal from an electronic control device to a servo mechanism is slightly delayed when the clutch is engaged without through idling to make the engaging timing proper.

Title: Communication method and parallel computer
Inventor: TANABE NOBORU
IPC: G06F15/177
Filed: 1994-01-21
Abstract: PURPOSE:To improve the utilizing efficiency of communication band width at a super-parallel computer for fine-grading processing and to improve the efficiency of fine-grading parallel processing at the same time by providing a means for indicating the omission of one part or the entire part of the transfer of transfer control information data. CONSTITUTION:It is investigated on the transmission side whether a control means exists at a transmitting means for data to be transmitted or not and when the control means exists, it is decided whether the transfer of a header as a sort of transfer control information can be omitted or not. When the transfer of the header can be omitted, the control means reports the omission of the header to the reception side. Simultaneously or continuously, the transmitting means transmits the data. Thus, the transfer time of transfer control information data is excluded or reduced, and a ratio to use a communication path for transferring the desired data to be originally transferred is increased. Therefore, in the case of processing for which throughput is decided by the communication band width, throughput can be improved.

Title: High frequency zerocross signal detecting circuit
Inventor: KOBAYASHI TAKESHI
IPC: H02M7/539
Filed: 1983-01-13
Abstract: PURPOSE:To suppress the irregularity in the phase delay of an output signal to each zero crossing point by symmetrically forming the input circuits of differential amplifiers for detecting the zero crossing point from a ground line. CONSTITUTION:A high frequency voltage eHF produced in a work coil is detected by a transformer PT, thereby producing positive and negative signal clipped in the same phase as the secondary side AC voltage through a resistor R and diodes D1, D2. This is applied through resistors R1, R2 to a differential amplifier DAMP to produce a rectangular output e0 clipped through the resistor R1 and a diode D3 from the output of the amplifier, thereby detecting the zero corssing point. In this case, the input terminal of the amplifier DAMP becomes symmetrical to the ground line by connecting the center of the secondary winding of the transformer PT to the ground line, thereby reducing the irregularity of the delay of the output e0 to 10ns.

Filed: 1988-01-13
Abstract: PURPOSE:To obtain a manually driven type printer having favorable operability and printing quality, by providing a means for pressing a head against a printing surface through a thermal printing ribbon therebetween, a means for pressing a driving roller means, and a displaceable means for enabling the driving roller means to be displaced relative to the printing surface. CONSTITUTION:A pressing force exerted by hand causes a driving roller to be displaced smoothly in the direction of an arrow A, away from a printing surface 60 while being securely pressed against the printing surface 60. Thereafter, a thermal head 1 is displaced further in the direction of an arrow D', and a pressing force in the direction of an arrow D'' is applied thereto by a head-pressing spring 11, resulting in the condition of h<=0 in which printing can be performed. Thus, the head 1 is prevented from being pressed against the printing surface 60 before the driving roller 2 is pressed in a series of operations, and the head 1 is brought into a printable condition after the driving roller 2 is securely pressed against the printing surface 60. Therefore, it is enough to provide such a setting as to supply an overcoming pressing force at the position at which the driving roller 2 is about to be moved while being pressed against the printing surface 60.
