Title: Electrodepositing method of zinc oxide film and electrodepositing device
Inventor: ARAO KOZO
IPC: C25D9/08
Filed: 1998-07-29
Abstract: PROBLEM TO BE SOLVED: To effectively remove a white powder produced in an electrodeposition bath, to maintain the reliability of the bath in a good state and to produce a good zinc oxide film by making an electrodepositing method include a process to keep the pH of a soln. low. SOLUTION: In the process to keep the pH of the soln., a valve 1071 is opened by a controller 1073 based on the measured pH by a pH glass electrode 1074, and nitric acid in a nitric acid reservoir tank 1072 having a low pH is added to soln. to keep the pH low. The pH of the soln. is preferably kept to <=2.0, and the concn. of nitric acid to be added is preferably >=0.01 M/l. Thereby, dissolution of a zinc oxide powder is started at a practical rate, and by controlling the pH to <=1.0, even a powder of a large particle size remaining in an electrodeposition cell or in the corner part of piping can be dissolved. By carrying out the process to keep the pH of the soln. low prior to the process to exchange the electrodeposition bath, the exchanging process of the bath can be completed only by discarding the used electrodeposition bath and replenishing with a new soln.

Title: Optional waveform generator
Inventor: KOBAYASHI YOSUKE
IPC: H03B28/00
Filed: 1991-08-26
Abstract: PURPOSE:To remove the limitation of the number of waveform data by simultaneously reading out each plural data from waveform data stored in two waveform memories in accordance with addresses alternately added to the memories and loading the read data to a shift register to speed up data reading. CONSTITUTION:The waveform memories 11, 12 are respectively constituted so as to simultaneously output waveform data corresponding to N addresses. An address generating part 13 generates an optional 1st address and the 2nd address preceding N addresses from the 1st address and adds its outputs to an address selector 14. The selector 14 alternately distributes the two addresses to the memories 11, 12, which output 2N waveform data in accordance with the applied addresses and add them to a data selector 15. The selector 15 is driven synchronously with the switching of the selector 14, alternately distributes the input data to outputs to the shift register 16. The register 16 shifts the 2N waveform data. Consequently limitation or the formation of waveform data can be removed.

Title: Control of cooling of dry process coke cooling tower
Inventor: TANAKA TOSHIROU
IPC: C10B39/02
Filed: 1982-12-09
Abstract: PURPOSE:To increase heat recovery in a dry process coke quenching tower and insure uniformity of the temperature of discharged coke, by controlling actions of discharging and regulating devices and cooling coke to a uniform temperature. CONSTITUTION:When an unbalance of the particle size distribution occurs in a circumferential direction and the calculated average temperature of coke at any discharge opening 6 becomes higher by a predetermined level than a total average temperature, the amount of coke discharged from a discharging device 7 at the discharge opening 6 is decreased and the speed of coke discharging and coke descending are reduced. As a result, the effect of coke cooling with a counter flow of the cooling gas is increased leading to uniform cooling of coke. When the unbalance of the particle size distribution occurs in a radial direction and the maximum value of coke at any discharge opening 6 becomes higher by a predetermined level than a total average temperature, the amount of gas from a central gas blowing section 9 is increased by a gas flow regulator 11 leading to increase in the contact ratio between coke and gas. Thus, the cooling effect on coke descending in the center is increased so that coke is cooled uniformly.

Title: Connecting device for power transmission member of drive shaft
Inventor: KAWAKAMI SHINYA
IPC: F16H48/12
Filed: 1981-12-26
Abstract: PURPOSE:To enhance tight adhesiveness so as to improve anti-abrasion and load capability by forming a surface improving coating on at least one portion of a power transmission contact surface in a drive shaft of a reduction gear for a car. CONSTITUTION:In a final reduction gear of a car, a companion flange 9 and a drive pinion shaft 1 are fastened together by means of a nut 11 and said flange 9, an oil slinger 13, the inner ring 2a of a conical roller bearing 2, a spacer 12 and the inner ring 3a of a conical roller bearing 3 are pressed together. Where the driving power transmitted to said companion flange 9 becomes larger, it exceeds the contact frictional force to slide on each other and after that, it is transmitted through splines 7, 10. At this time, since the noise is generated due to the stick slipping and the abrasion is increased, a surface improving coating 14 such as a coating film treated with manganese phosphate is applied on the surface of an oil slinger 13. Thus, anti-abrasion and a load capability are enhanced and generation of a noise can be suppressed.

Title: Window opening and closing device
Inventor: SAKANO MASATAKA
IPC: E05F11/48
Filed: 1997-08-08
Abstract: PROBLEM TO BE SOLVED: To make it possible to simply have fully opened or semi-opened window without requiring any large-scaled device. SOLUTION: The rotation of a winding drum 21 is transferred to a stop claw 520 of a stop arm 510 through an idler gear 110, an intermediate gear 120 and intermittent gears 210, 220, 310, 320, 410 and 420, and a claw lever 530 is pivoted with the stop claw 520. When the interlock of the drum gear 101 is released by a lock claw 532 in the case of a semi-opened window, a wire cable is let out, and the stop claw 520 is pivoted as well as the rotation of the winding drum 21 to drive the claw lever 530. When the claw lever 530 is pivoted to interlock the lock claw 532 with the drum gear 101, the rotation of the winding drum 21 is stopped to complete a state of the semi-opened window.  In the case of a fully opened window, the interlock of the stop arm 510 is released to slip the position to the right rotational direction so that the claw lever 530 can not be driven by the pivoting stop claw 520. Even if the winding drum 21 reaches the number of revolutions equivalent to the semi-opened window, the claw lever 530 is not interlocked with the drum gear 101, and the winding drum 21 is rotated up to the fully opened window to let out the wire cable.

Title: Flow rate abnormality diagnostic device
Inventor: NATSUME AKINORI
IPC: G08B21/00
Filed: 1988-08-30
Abstract: PURPOSE:To evade malfunction due to a detection error by stopping abnormality diagnosing operation when a load signal and an opening extent command signal for a flow rate control valve are lower than a set value. CONSTITUTION:A comparator 2 inputs a plant load signal 21 and outputs an output signal 22 when the value is smaller than a set value. A comparator 3 inputs a flow rate control valve opening extent command signal 31 and outputs an output signal 32 when the value is smaller than a set value. Further, an AND gate 4 inputs the output signals 22 and 32 of the comparators 2 and 3, and send a diagnosis stop signal 41 to a NOT circuit 5 when the both satisfy an AND condition. The NOT circuit 5 outputs a diagnostic block signal 51 unless the AND gate 4 outputs the diagnosis stop signal 41. Then an AND gate 6 inputs a diagnostic block signal 51 from the NOT circuit 5, and an abnormality and trouble signal 11 from an abnormality diagnostic means 10, and outputs an abnormality decision signal 61 when the both satisfies an AND condition. Consequently, the malfunction of the device due to the detection error at the time of a low flow rate can be evaded.
