Title: Lead acid storage battery
Inventor: MATSUMURA YASUSHI
IPC: H01M4/14
Filed: 1990-07-23
Abstract: PURPOSE:To improve a service life and storage property of a battery by carrying out chemical conversion under the conditions that a slurry containing a lead oxide in an alkali solution is applied to the surface of a cathode electric collector. CONSTITUTION:A cathode plate having alpha-PbO2 rich surface of the electric collector and an x-ray diffraction peak ratio (beta/alpha) of /3-PbO2 and alpha-PbO2 in the active mass layer in the boundary between the electric collector and the active mass gradually decreasing toward the electric collector is obtained by, for example applying a lead oxide slurry kneaded with an alkali solution to the surface of the cathode collector and applying a lead oxide paste on it and then carrying out a conventional chemical conversion.

Title: Power supply device
Inventor: MORISHITA YOSHIICHI
IPC: G05F5/00
Filed: 1986-08-20
Abstract: PURPOSE:To prevent a load connected to a controlled system from generating malfunction even in a transient state at the time of turning on or off of a power supply by effectuating either one of two voltage supplying means faster than the other by an effectuating means. CONSTITUTION:In the transient state immediately after turning on a switch 14, a capacitor 32 is charged also with an output current of a constant voltage circuit 26 in addition to an output current of a full wave rectifier 30. Since the charge of the capacitor 32 is accelerated, a control circuit 38 can be actuated before a voltage V1 to be supplied to a driving circuit 24 reaches a critical value E0, so that the driving circuit 24 can be prevented from malfunction immediately after turning on the switch 14. Since the charge of the capacitor 32 is maintained by the output current of the circuit 26 during a prescribed period at the time of turning off the switch 14, the control circuit 38 is not disabled before the voltage V1 applied to the driving circuit 24 is dropped to the critical value E0. Thereby, the driving circuit 24 does not generate malfunction even if the switch is turned off.

Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To incinerate waste to be burnt such as waste plastics which requires a large amount of air to burn it and has to be agitated widen it is burnt by blowing air against the waste by blowing air in a finely divided manner from air nozzles and feeding power through a power cable to a blower for combustion to rotate a furnace body normally and reversely. SOLUTION: Waste to be incinerated fed into a furnace body 1 from a waste feed hopper 8 is ignited by a burner 7 and burnt as it is moved rearward while burning surface of the waste is being exposed by agitation caused by the rotary motion of the body 1. The furnace body 1 is inclined downwardly at an angle of 1-5 degrees to allow the waste to be easily moved to the rear of the furnace. The body 1 can be rotated normally or reversely by means of a reducer 10 driving. Power for driving a combustion blower 4 is fed through a power cable 12. Thus, not only sludge but also waste plastics, waste wood, waste paper, waste rubber, residue of food or a mixture thereof can be completely burnt.

Abstract: PURPOSE:To stably transfer an image by providing a recording part for forming an image to a transfer recording layer, a transfer part for transferring the image to a medium to be recorded, a separation member for separating a transfer recording medium after transfer from the medium to be recorded and a contact means capable of being contacted with said separation member under pressure. CONSTITUTION:When a transfer recording medium 1 is successively delivered from a supply roll 2, and light and heat are applied to the transfer recording layer 1b of the transfer recording medium 1 corresponding to an image signal in a recording part 3, an image is formed on the transfer recording layer 1b. Further, the transfer recording layer 1b having the image formed thereto is contacted with recording paper 8 under pressure in a transfer part 4 and heated to transfer the transfer image to the recording paper 8. The transfer recording medium 1 and the recording paper 8 passing through the transfer part 4 are ted to a separation roller 5. In this case, since the transfer recording medium l and the recording paper 8 are held between the separation roller 5 and a pressure contact roller 14a in a superposed state, a separation position does not change when the leading end of the recording paper 8 cuts in between a pair of discharge rollers 13a, 13b. The pressure contact roller 14a rotates while generating slip by a clutch 15 and feeds the recording paper 8 and, therefore, no slackening is generated in the recording paper 8.

Title: Crystal vibrator and manufacture therefor
Inventor: IDE TOSHINORI
IPC: H03H3/02
Filed: 1996-07-05
Abstract: PROBLEM TO BE SOLVED: To provide crystal vibrator with less dispersion by soldering an electrode formed crystal vibration piece to an airtight terminal, turning it to a half-complete crystal vibrator, then washing it, performing a heat treatment in nitrogen atmosphere, then adjusting a vibration frequency and performing sealing. SOLUTION: An electrode formation process (11), an assembling process (12) and a washing process (13) are the same as a conventional technique. A nitrogen atmosphere heat treatment (14) is then performed to the washed half-complete crystal vibrator. Temperature distribution in a heating tank is easily uniformized by the convection of gaseous nitrogen, heat transmission to the half-complete crystal vibrator is quick and moisture absorbed to the half-complete crystal vibrator is sufficiently removed in a short time. After the nitrogen atmosphere heat treatment (14), leaving time in atmosphere is shortened as much as possible and an (f) adjustment process (15) is started. In the (f) adjustment process (15), silver is vapor-deposited to the surface of the crystal vibrator inside a vacuum tank.  A vibration frequency is adjusted by the (f) adjustment process and the next sealing process (16) is immediately started. Thus, since frequency adjustment and sealing are performed in the state of less moisture absorption, the difference of an (f) adjustment target value and a complete vibration frequency is made small and the dispersion is made small as well.
