Title: Heat transfer pipe with grooves
Inventor: KUWABARA HEIKICHI
IPC: F28F1/12
Filed: 1981-02-06
Abstract: PURPOSE:To raise the efficiency of heat transfer, by increasing the capillary force by forming grooves such that the width of each groove is made small at the base portion of the fin and made increased gradually toward the top. CONSTITUTION:A fin 6B of a heat transfer pipe 6 is shaped such that its thickness is large at its base portion 6B1 and decreased gradually toward the top, and the top portion 6B2 of the fin 6B is shaped to have a curved surface. Resultantly, each of elongated grooves 7 defined between adjacent two fins 6B has a small width at its bottom 7A but the width is increased gradually toward the inlet portion 7B. Thus, since the curvature of liquid in the grooves 7 can be reduced, capillary force of the liquid is increased whereas the gravity force of the liquid acted in the opposite direction to that of the capillary force is decreased, so that water film produced in the grooves 7 spreads to the tops 6B2 of fins 6B. Therefore, heat transfer through vaporization of the water film can be promoted effectively.

Title: Electronic watch with alarm
Inventor: UEDA JIYUN
IPC: G04C3/00
Filed: 1979-02-14
Abstract: PURPOSE: To inform an hour signal at correct time with inexpensive circuit in an electronic watch with an alarm by forming one hand of magnetic material and disposing a permanent magnet on a dial plate.  
     CONSTITUTION: When a minute hand 52 is formed of magnetic material and a permanent magnet 54 is disposed on the position of twelve o'clock on a dial plate, the magnet 54 magnetically attracts the minutes hand 52 at every one hour to produce load change on the rotor of a step motor. When the duration 45 of the drive pulse of the step motor is set narrow and the rotor is rotated due to the load variation of the rotor, a correction pulse 47 is generated to return to normal rotation. When the magnet 54 is magnetically attracted to stop the rotor to produce a correction pulse 47, it is detected to generate an alarm. Thus, the hour alarm can be generated with a simple circuit. If the second hand is made of magnetic and one hour counter is provided, the hour alarm may be furhter accurately generated.

Title: Fuel injector
Inventor: FUKAMI AKIRA
IPC: F02D1/06
Filed: 1978-02-14
Abstract: PURPOSE: To increase the quantity of injected fuel through simple constitution at the time of warm-up of an engine, by controlling the negative pressure of a Venturi part for a pneumatic speed governor depending on the state of warm-up of the engine.  
     CONSTITUTION: A negatie pressure controller is provided. This controller consists of a conduit 21, a solenoid valve22 and a warm-up detector 23 which controls the conduit and the solenoid valve. If the temperature of cooling water of the engine 1 is lower than a set level when a throttle valve 6 is entirely open and the engine 1 is idling for warm-up, the warm-up detector 23 is turned on to open the solenoid valve 22. Then, auxiliary air is supplied to an intake pipe 3 at the downstream side of the throttle valve 6 through the conduit 21 and the flow rate of air through the Venturi part 7 decreases. As a result, the negative pressure of the Venturi part falls and the quantity of injected fuel for the engine increases.

Title: Optical disk reproducing device
Inventor: TAKEYA TOMOYOSHI
IPC: G11B7/09
Filed: 1995-02-02
Abstract: PURPOSE: To automatically converge to be an excellent tracking state by rotating a diffraction light emission means so that the level of a tracking error signal becomes largest. CONSTITUTION: Tracks T1 , T2 are irradiated with a main beam (0-order light) SM and sub-beams (±1st-order diffracted light) SA, SB obtained by passing a laser of a laser diode 16 through a diffraction grating 17. A photodetector 2 is a quadripartite photodetector, and it receives return light obtained by reflection of the main beams SM reflected on the surface of an optical disk 1 and makes it a detection signal. The photodetectors 3, 4 detect the return light from the sub-beams SA, SB respectively. A subtracter 5 subtracts the detection signals each other by the sub-beams light received by the photodetectors 3, 4, and generates a tracking error signal TE.  Since the diffraction light emission means is rotated so that the level of the tracking error signal becomes largest, the excellent tracking state is converged automatically even when the optical disk having any tracking pitch is loaded.
