IPC: G11B15/26
Filed: 1993-03-30
Abstract: PURPOSE: To prevent the miss phenomenon of a video or a noise during the change of an operational mode by quickly rotating an idler to a feeding reel or a winding reel side, and preventing a video tape from being slackened. CONSTITUTION: In a reel drive unit, rotating arms 36 and 37 are connected with the both sides of an idler bracket 32 which supports an idler 23, and each rotating arm is rotated by the right and left sliding of a sliding board 26 by the rotation of a cam gear. Then, the idler 23 is rotated so as to be selectively connected with one of a feeding reel 21 and a winding reel 22 so that an operational mode can be changed. Thus, a video tape can be prevented from being slackened during the change of the operational mode, and the miss and distortion phenomena of a video and a noise or the like can be prevented.

Then, the display disk 29 on the 1st process cartridge 21 side is so decelerated as to rotate less than one turn in 10,000 times. The number of revolutions at which the developing sleeve 5c runs out of its life is assumed to be, for example, 200,000 times. Then, the display disk 38 on the 2nd process cartridge 22 side is so decelerated as to rotate less than one turn in 200,000 times. The exact judgement of the life of the 2nd process cartridge having the developing device is thereby permitted.

Title: Ni-type component material for fused carbonate fuel cell excellent in corrosion resistance
Inventor: YANAGIDA MASAHIRO
IPC: H01M8/02
Filed: 1987-03-25
Abstract: PURPOSE:To improve corrosion resistance under a fused carbonate environment, by incorporating specific amounts of Si and Al into an Ni-type component material for fuel cell. CONSTITUTION:An Ni-type component material for fused carbonate fuel cell has a composition consisting of, by weight, 0.4-5% Si and/or 0.1-10% or 20-40% Al and the balance Ni or Ni-Cr with inevitable impurities. In this composition, Si has a function of strengthening an oxide film formed on the surface layer part of the material at a gas-liquid interface. When Al is incorporated by 0.1-10%, a stable alpha-phase in which Al is allowed to enter into solid solution in Ni is formed and, when 20-40%, a beta'-phase in which the ratio of Al to Ni is regulated to 1 to 1 is formed. By this material composition, corrosion resistance under a fused carbonate environment is improved, and, when oxidation treatment is further applied to the above material surface, corrosion resistance can be improved to a greater extent.

Title: Air conditioner for vehicle
Inventor: SAKURADA MUNEO
IPC: B60H1/32
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To maintain the air-conditioning property for a long time by providing an adjusting means to adjust the urging force of a coil spring of an expansion valve, and adjusting the opening characteristic of the expansion valve during the idling stop to delay the raising speed of the temperature of the air to be fed from an air conditioner during the idling stop as much as possible. SOLUTION: In an expansion valve 24 which adiabatically expands the liquid refrigerant high in temperature and pressure to make a refrigerant low in temperature and pressure in a refrigerating cycle of an air conditioner for vehicle, the pressure in an upper pressure chamber is increased to inflate a diaphragm downward when the temperature on an outlet side of an evaporator 25 is high, and a working bar connected to a heat sensing bar is lowered against the spring force of a coil spring 8 to press down a valve element 5 and increase the opening of an orifice 3. During the idling stop, a motor drive device 27 is driven to rotate a stepping motor 12 according to the signal in the idling stop mode from an ECU 28, and an adjustment nut 11 is moved downward to reduce the urging force to the coil spring 8.

Title: Starting control device of internal combustion engine
Inventor: FUKAZAWA OSAMU
IPC: F02M25/07
Filed: 1998-03-23
Abstract: PROBLEM TO BE SOLVED: To ignite an air-fuel mixture sufficiently atomizing an injection fuel at the time of starting without causing increase of the number of parts, to be consistent improvement in startability with reduction of costs. SOLUTION: This control device judges whether the number of injection is more than the specified number of injection N or not (step 204) by counting the number of fuel injection at the time of starting (steps 200-203). Hereby, the specified number of injection N is the number of injection required necessary for time required until an air-fuel mixture which fuel injected for the first time is atomized and easy to ignite is formed and is set in accordance with cooling water temperature, fuel pressure, etc. When the number of injection is less than the specified number of injection N, atomization of fuel is considered to be still insufficient, and only fuel injection is carried out at the initial stage of an air intake process by cutting ignition (steps 205, 207).  Thereafter, at the point of time when the number of injection becomes more than the specified number of injection N, ignition is started while continuously carrying out fuel injection (steps 206, 207). Consequently, it is possible to ignite fuel injected within an ignition cutting period after sufficiently atomizing it and to improve startability.

IPC: G05B13/02
Filed: 1982-04-30
Abstract: PURPOSE:To perform a control to obtain the maximum value of the general efficiency, by changing the direction of the control quantity in response to the direction to the extreme value of the change component between the quantities to be controlled of this time and the previous time which are obtained periodically and then continuing the above-mentioned change of direction to approximate the quantity to be controlled to the extreme value. CONSTITUTION:When an operation start command signal (h) is delivered at a time point TO, a signal (s) is delivered as an output signal (g) from a switch 9 and just for a period TA. A switch 11 delivers the supplied signal as it is for the period TA by a signal (j) and then applies it to an integrator 12. As a result, the signal (s) is applied as it is to the integrator 12 from a generator 8. The signals (h) and (j) are turned off in a period TB, and therefore signals (i) and (k) are held. Then the output signal (k) of the integrator 12 is applied to a PI controller 2, and a new control quantity m1 is decided. Then a new quantity f1 is decided to the quantity m1. In such a way, the sampling time is successively shifted to decide the set value of control quantity in the direction where the quantity to be controlled varies to approximate to the extreme value.

Abstract: PURPOSE:To obtain a reproduced screen of high quality, by using a variable delaying device such as a CCD delay line, etc. to compensate both residual time axis error and dropout noises. CONSTITUTION:The composite color video signal delivered from a demodulator 3 is supplied directly to a CCD delaying device 6 as long as no dropout of signals is detected by a dropout detector 4. When a dropout of signal is detected, a switch 5 is changed over to the side of a contact (b) to supply a delayed signal to the device 6. A phase comparator 11 and an LPF12 detect an error signal showing a shift between the delay time of the device 6 and a horizontal scanning period, and feeds the error signal to an adder 13. A time axis error detecting circuit 8 detects an error signal showing the time axis variation component which is contained in a video signal. The error signals of the LPF12 and the circuit 8 and added together by the adder 13 to control a voltage control oscillator 7. The output clock signal of the oscillator 7 is fed to the device 6, and a delay decided with the clock frequency is applied to the demodulated video signal.
