Abstract: PURPOSE:To eliminate fluctuations in power supply voltage and protect the input of an electronic component by connecting one side of a series circuit of a Zener diode and a diode to the input side of the electronic component and the other side to the ground. CONSTITUTION:One side of a series circuit of a Zener diode 8 and a diode 9 is connected to the input side of an electronic component 4 such as A/D converter or the like, and the other side is connected to ground G of power supplies 1 and 2. If, for instance, the output of an amplifier 5 is saturated at a negative side, not only an input protection diode 7 of electronic component 4 but also a circuit of the Zener diode 8 and the diode 9 connected between the input of the electronic component 4 and a common ground terminal of a first power supply 1 begin to operate and a current flowing from a second power supply 2 to the amplifier 5 is eliminated by applying a current from the ground of the power supply having a larger capacity to the amplifier 5.

Title: Production of engine valve
Inventor: MINO KAZUAKI
IPC: C22F1/10
Filed: 1985-05-28
Abstract: PURPOSE:To improve the wear resistance of a valve by precision-casting said valve of an Ni alloy which contains specific % of Cr and can precipitate prescribed % of the gamma prime phase of an intermetallic compd. then subjecting the required part to a hardening treatment. CONSTITUTION:Cr is incorporated at 15-30wt% into the Ni alloy material in order to provide high-temp. corrosion resistance. A prescribed ratio each of Al, Ti, Nb, Ta, V, W, etc. are incorporated therein to permit the precipitation of the gamma prime layer at 30-60% (by volume). The engine valve is precision-cast by using such Ni alloy. About 20% work strain is applied to the face part of the valve by using a press, etc. Since the gamma prime quantity of the alloy material is set large, the hardening quantity is increased and the decrease of the hardness during high-temp. use is lessened. The wear resistance of the valve is thus improved.

Filed: 1990-04-27
Abstract: PURPOSE: To make it possible to precisely measure the tape residual time according to running state by successively executing addition and subtraction based on the beforehand calculated residual time even at the time of a high speed running and the speed change of a tape. CONSTITUTION: This recorder is provided with a microcomputer 20 generating a servo control signal by a relevant mode by a key command signal from a key input part 10, receiving a generated reel pulse and calculating the present tape residual time and a period of a feeding reel. Then, in the high speed running mode or the speed change mode, after each one revolution period of the reel elapses, a fixed variable amount of a rotational period is subtracted or added from the just before rotational period according to the running direction, and a new one revolution period is obtained. Then, the value equivalent to the new one revolution period is subtracted or added from the beforehand inputted running residual time at every one revolution time of the tape according to the running direction to be recorded as the new residual time.  Thus, the tape residual time is measured precisely even at the time of a high speed running or the speed change of the tape.

Title: Diaphragm driver
Inventor: OONUMA TAKASHI
IPC: G03B9/02
Filed: 1980-08-21
Abstract: PURPOSE:To prevent the hunting phenomenon with a low cost, by adding a switching circuit between a motor and a circuit that drives the motor. CONSTITUTION:In case when an image is too dark, an iris signal T transmits the information to open the disphragm. Thus the current flows to an input point 14 of a motor driving amplifier 2. A motor 8 turns in the direction to open the diaphragm, and a diaphragm ring 11 moves. When the diaphragm reaches the open end, a wiper brush 19a of diaphragm end detection switch 19 touches a conduction end 19b. Thus the voltage at a point 17 becomes zero to stop the motor 8. Then the signal T transmits the information to close the diaphragm since the image is too bright. Thus the voltage of -V is produced at the point 14, and the motor 8 turns in the direction to close the diaphragm. The brush 19a touches a conduction end 19c at the diaphragm end to set the voltage of the point 19 at zero. Thus the motor 8 is stopped. In such constitution, the hunting phenomenon can be prevented with a low cost.

Filed: 1994-05-27
Abstract: PURPOSE:To prevent the possibility of erroneous mounting of an ink tank even in the case of either monochrome or color by providing a sensing means for sensing the mounting and a changeover means for changing over a first erroneous mounting prevention means to a second erroneous mounting prevention means or vice versa in compliance with the result of whether the first ink jet means is sensed or a second ink jet means is sensed. CONSTITUTION:When a color head 1 is mounted on a carriage, a protrusion 12 is sensed by a photointerrupter 13, and a color inner plate component 9b is positioned on an ink tank holder bottom plate 8 by an actuator 10 based on the CPU command. Only four tanks 3, namely K, C, M and Y, can be mounted on respective four ink tank mounting position because of the above arrangement. On the other hand, when a monochrome head 1 is mounted on the carriage, nothing is sensed by the ink interrupter 13 as there is no protrusion 12, and a monochrome inner plate component 9a is positioned on the bottom plate 8 by the actuator 10 based on the CPU command. At that time, as the K color tank only can be mounted on the four tank mounting position, the erroneous tank mounting on its respective heads is prevented.
