Title: Agitating piece for applicator
Inventor: KODAMA HIDETOSHI
IPC: C23C28/00
Filed: 1989-11-30
Abstract: PURPOSE:To obtain an agitating piece for applicator for preventing the coagulation and solidification phenomena of pigment used as a coloring material in an applicator using high-viscosity liquid by providing an Ni alloy plating layer to an iron substrate and further providing a chromate film to the above layer. CONSTITUTION:An Ni alloy plating of Ni-P, Ni-Sn, Ni-W, etc., is applied to an iron substrate of proper shape, such as spherical shape or bar shape. Subsequently, e.g. a chromate film is formed on the above Ni alloy plating by an immersion chromating method, that is, e.g. a chromate film is formed by using a solution containing chromate anhydride, H2SO4, and NaF by 200g/l, 20g/l, and 10g/l, respectively, and carrying out immersion at 50-60 deg.C for 1-3min. In the resulting agitating piece for applicator, the chromate film on the surface acts as a barrier even if a substance liable to generate chlorine gas, such as trichlene solvent, is used as a solvent for the coating solution. Further, as the countermeasure against local corrosion, the corroded part is restored by means of the oxidizing action of Cr<+6>, by which corrosion resistance can be improved and the formation of rust can be prevented.

Title: Digital circuit
Inventor: KASAME TOMOHIDE
IPC: H03K5/01
Filed: 1992-11-24
Abstract: PURPOSE:To prevent malfunction due to noises by interposing a mask circuit for outputting logic multiplication with pulse input and a filter circuit for removing the noise with a timer circuit for adjusting noise removal time in the circuit in a pulse signal line. CONSTITUTION:At a digital circuit, mask signals M are generated for the period of time for which the cycle of input pulses P of a previous time and a maximum cycle fluctuation ratio VET are multiplied. While the mask signals M are generated, that is, while the signals M are at an H level, that is, while the output signals of an inverter 25 is at an L level, the rise edge of the input pulse P is not transmitted to the post stage logic circuit. Thus, in the case of the noise fit in the period when the mask signals M are generated, the noise can be removed regardless of its level and a time width. Thus, the malfunction to the noise of the logic circuit can be prevented. Also, the rise edge of the input pulse P can be transmitted to the logic circuit without generating time delay.

Filed: 1987-12-10
Abstract: PURPOSE:To prevent a cancel resulting from a minute reverse rotation of a steering shaft by moving a rack relatively with a pinion gear through the gearing of the pinion gear and the rack, and making a turn lever canceled. CONSTITUTION:A pinion 25 is geared with a rack 26 which is formed at an incline 22b, and a frame 11 is rotated together with a cancel member 20. As a result, the reverse turning amount of a steering shaft necessary to cancel a turn lever 3 can be made constant. Thereby, a trouble of canceling the turn lever 3 by a minute reverse rotation of the steering shaft is prevented. And, since the pinion 25 and the rack 26 are not geared when the car lane is changed, the turn lever 3 is canceled by stopping the operation of the turn lever 3 as is the normal cancel mechanism.

IPC: F02D41/00
Filed: 1987-12-11
Abstract: PURPOSE:To prevent a combustion noise from increasing by performing such control as advancing the timing of pilot injection to the main injection according to an engine temperature detected. CONSTITUTION:In a Diesel engine which is constituted so as to perform pilot injection prior to the main injection, there are provided with a detecting means detecting an engine temperature and a control means advancing the timing of the pilot injection to that of the main injection when the engine temperature is less than the specified value. In brief, when the detected value of an engine water temperature sensor 21 is less than the specified value, a position of a control rack in a fuel injection pump P is controlled in a direction where the timing of the pilot injection is advanced. With constitution like this, at the time of engine cold, the timing of the pilot injection is advanced to the main injection by the control means, so that an ignition lag due to the pilot injection is prevented from occurring. In addition, since there is unnecessary to advance the timing of the main injection, an increase in a combustion noise will not occur at all.

Abstract: PURPOSE:To freely change a characteristic by reducing the large change of a gain at a point at which the characteristic is switched, in the digital gamma correcting circuit of a video camera. CONSTITUTION:The level of an input signal X is detected by subtracters 2 and 3, coefficient generators 5 and 6, and control signal conversion circuit 14. A first subtracter 4 subtracts the coefficient values of coefficient generators 7-9 switched by a signal selector 10 from the input signal X. A first multiplier 13 squares or multiplies by -1 the output of the first subtracter 4. On the other hand, the second multiplier is constituted of coefficient units 15-17, and a signal selector 18. The output is subtracted from the coefficient of the coefficient generators 27-29 selected by a signal selector 30 by a second subtracter 26. Each signal selector 10, 12, 18, and 30 is controlled by the output of the control signal conversion circuit 14 so that the appropriate coefficient can be selected. As the result, the output of the second subtracter 26 is {-(X-27)2/8}+92 when the input signal X is 0 to 21, {-(X-200)2/256}+ 212 when the X is 22 to 127, and (X/2)-128 when the X is 128 to 255.
