Title: Vane-type air pump
Inventor: HASEGAWA AKIRA
IPC: F04C18/344
Filed: 1990-08-30
Abstract: PURPOSE:To prevent pressure from lowering as a result of gapping and leakage and intend higher pressure by drilling a communication hole in a vane, making an air pressure leading groove in a thrust plate and mounting a sealing material on the outer periphery of the air pressure leading groove to form an air pressure leading portion. CONSTITUTION:A communication hole 32 is drilled between the near-end portion 30 and the bottom portion 4B of a vane 4. An air pressure leading groove 40 is made in the outer periphery on the back of a thrust plate 7. In addition, a sealing material is mounted between the opposite face 8A of a counter-drive- side cover 8 opposite to the outer periphery on the back of the thrust plate 7 and the outer periphery of the air pressure leading groove 40 to form an air pressure leading portion 43, in which compressed air is led. As a result, a pump room communicates with the space portion of a vane groove via a communication hole 32 to bring about no differential pressure and no gap between the end 4A of the vane 4 and the inner periphery of a liner ring 2. Compressed air is led into the air pressure leading portion 43 to push the outer periphery of the thrust plate 7 against the back of a counter-drive-side side plate without a gap between both of these.

Title: Ink jet recording head
Inventor: ODA HAJIME
IPC: B41J2/015
Filed: 1985-10-11
Abstract: PURPOSE:To enable the uneven condition of an air flow at each air discharge outlet to be suppressed by providing an air feeder pipe connected at right angles to the discharge direction of the air discharge outlet in an air chamber and allowing the air to be fed to gyrate in the air chamber. CONSTITUTION:In ink jet recording using an air flow, one end of an air feeder pipe 14 is connected to the side of an air chamber at a lop-sided position in a direction at right angles with the discharge direction of an air discharge outlet 10 so as to avoid the assumption by the feeder pipe of an opposite position to an internal wall 4. On the other hand, the other end of the air feeder pipe 14 is connected to an air supply source. An air flow to be supplied from the air feeder pipe 14 flows gyrating in the air chamber 6, then is stabilized and finally converges into an air flow path 7 between an air nozzle plate 3 and an ink nozzle plate 5 from the surroundings. The air thus converged can be injected through each air discharge outlet 10, generating a sudden curve. Consequently, the uneven condition of an air flow (velocity, pressure and discharge direction) from each air discharge outlet can be suppressed.

Title: X-ray ct device
Inventor: YOSHIOKA TOMOTSUNE
IPC: A61B6/03
Filed: 1989-09-04
Abstract: PURPOSE:To accurately correct a dark current of an X-ray detector by holding a temperature of the X-ray detector to a value separated from the peripheral temperature while decreasing or increasing the temperature at a fixed speed just before measurement is started and correcting the dark current as a change in the fixed speed by the lapse of time. CONSTITUTION:An X-ray is not exposed, and in a condition that an X-ray detector vessel temperature is changed at a fixed speed, a dark current in each channel is measured two times with a predetermined time interval. From these two times measured values and measuring time interval, a changing speed of the dark current in one clock of a timer circuit 15 is calculated with this value set to a dark current correction amount data memory 14. When measurement is performed, in the condition that the X-ray detector vessel temperature is changed at the fixed speed, the dark current of each channel is measured just before X-ray exposure with a value of the current written in a dark current value data memory 13. A value of the dark current correction amount data memory 14 of the same channel is added to or substracted from the value of each channel in every clock of the timer circuit 15. A value of the dark current value data memory 13 always agrees with the value of the dark current changed in a photodiode of the channel.

Title: Heat exchanger
Inventor: YAMAMOTO KEN
IPC: F28F1/32
Filed: 1985-10-11
Abstract: PURPOSE:To increase the heat transfer area of a heat exchanger, thin a temperature boundary layer, which otherwise precludes heat transfer, and provide the heat exchanger having high heat transfer efficiency by a method wherein bending configurations, no interfering the direction of air stream mutually, are formed by embossing sections, protruded into the same direction and neighboring with each other. CONSTITUTION:When high-temperature air flows between fin plates 1, heat exchange is effected between the fin plates 1 as well as heat transfer tubes 2 and the air. In this case, an air layer having very low flow speed and called as a temperature boundary layer, is generated in a boundary surface between a heat transfer surface and the air. The flow speed of the air is increased upon passing between the heat transfer tubes 2 because of the decrease of the sectional area of a flow path and, then, the air flows into an area provided with a punching sections 3. The embossed sections 3 are embossed to the same direction and the corrugations of neighboring embossed sections are formed so as not to interface with each other, therefore, the development of the temperature boundary layer is not caused due to the continued temperature boundary layer and the temperature boundary layers become independent on individual embossed sections. Accordingly, the boundary layer becomes thin and the heat transfer efficiency of the heat exchanger may be improved.

Filed: 1983-11-30
Abstract: PURPOSE:To shorten the OFF time of an output TR by discharging charge applied at the ON of the output TR through an FET connected between the source and drain of the output TR in parallel. CONSTITUTION:A photovoltatic element 1 is arranged between the gate and source of an FET type output TR2, a normally off MOSTR4 in which the threshold voltage of the gate is lower than that of the TR2 is arranged in parallel with the element 1 and a photovoltatic element 5 is arranged between the cathode of the element 1 and the gate of the TR4. When the output TR2 is turned off, only the TR2 acts as a capacitor like an equivalent circuit. Since the TR4 is disconnected at first, the discharged current from the TR2 flows through the diode 1 and then flows through the element 1, 5, positive voltage is applied to the gate of the TR4 and the TR4 is connected, so that the charge of the TR2 is discharged through the TR4. The time from the start of the discharge of the TR2 to the ON of the TR4 is shortened on the basis of the relation of said threshold values and the charge of the TR2 is discharged through the diode 1 and the TR4.
