Title: Sealed lead acid battery
Inventor: OGUMA MIKIO
IPC: H01M10/34
Filed: 1986-03-19
Abstract: PURPOSE:To apply appropriate pressure to a plate group and to obtain a plate group whose oxygen absorbing reaction is not disturbed and whose automated production is easy by using a perforated heat-shrinkable tube and covering the plate group from the upper end to the lower end with the tube, then shrinking the tube. CONSTITUTION:A plate group is covered with a heat-shrinkable tube from the upper end to the lower end, and accommodated in a container made of a synthetic resin film. An electrolyte is retained only in positive and negative plates 1, 2 and a separator 6. Lead terminals connected to the lugs 1', 2' of the positive and negative plates 1, 2 are drawn out from an opening of the container, and the opening is melt-bonded to produce a sealed lead-acid battery. Since holes 4 are perforated in the tube, oxygen generated in the positive plate 1 during charge comes in contact with the negative plate 2 through holes 4, and is absorbed in the negative plate 2. Since the plate group is appropriately compressed and absorption reaction is smoothly performed in the holes, good charge-discharge performance can be obtained in spite of using the thin container. The insertion of the plate group into the tube is performed at one time and automated production is easy.

Title: Power source circuit
Inventor: DOI SHINICHI
IPC: H02M3/28
Filed: 1999-03-09
Abstract: PROBLEM TO BE SOLVED: To obtain a power source circuit capable of preventing destruction of an element and properly detecting generation of a short-circuit. SOLUTION: When an output terminal S1 is short-circuited while a DC voltage V1 is being supplied to a CCD imager, terminal voltage of a resistor R10 changes from a high level to a low level. As a result, output of an EXOR circuit 16a shows a high level, a transistor T6 is changed from an off state to an on state. Then, voltage to be provided in a short-circuit detecting circuit 20 is remarkably lowered and thus, the short-circuit is detected. When the short- circuit is detected, a controi circuit 18 is promptly disabled by the short-circuit detecting circuit 20. As a result, output of a control pulse is interrupted and the off state is continuously taken by the transistor T3. Namely, input of a battery Vs is interrupted. When the short-circuit is generated in the output terminal S1, the transistor T3 is promptly turned off, therefore, a transistor T1 is not destroyed.

Abstract: PURPOSE:To shorten the time till a relief action after a high pressure part rises to the predetermined pressure and improve the responsiveness by forming a pressure control valve so that the pressure oil of the high pressure part is flowed to a back pressure chamber through an orifice when a piston is moved to a back pressure chamber side a little and the high pressure part and a low pressure part is communicated with each other. CONSTITUTION:When a high pressure part 20 becomes more then the predetermined pressure, since the high pressure oil is flowed from a lateral hole 27 and a transparent hole 23 to a back pressure chamber 25 to forcedly open a pilot poppet 26 and is discharged to a low pressure part 21, the differential pressure is generated before and after a piston 14 to move the piston 14 to right, resisting to a spring 15. Since the lateral hole 27 is thereby sealed with a relief poppet 13, the pressure oil of the high pressure part 20 is flowed from an orifice 22 and the transparent hole 23 into the back pressure chamber 25, and the differential pressure before and after the relief poppet 13 becomes large, and the relief poppet 13 is moved to right to communicate a high pressure port 17 with a low pressure port 18. Namely, the relief action is performed before the piston 14 abuts to a rejecting part 26a of the pilot poppet 26.

Title: Paper feed mechanism

IPC: B41J15/16
Filed: 1989-03-16
Abstract: PURPOSE:To prevent print misalignment at the time of forward line feed and backward line feed to increase line feed accuracy by providing a mechanism in which a pinch roller becomes a load on the feed by a tractor wheel during backward line feed. CONSTITUTION:A pair of pinch rollers 26, 27 are provided which transport an excess amount of form 100 to a tractor wheel 1 at the time of forward line feed. The pinch roller 26 has a one-way clutch 26 which makes it possible to only transmit a drive force in an arrow A direction. If the tractor wheel feeds the line forward, the pinch roller 26 also rotates forward in the arrow A direction to hold the form 100 passing through a printing section 2 between the roller 26 and the pinch roller 27 so that the form is given a transport force. In addition, the roller 26 rotates, overfeeding the form 100, and consequently, the form 100 is transported without becoming loose. In addition, the pinch roller 26 becomes a load by the action of the one-way clutch, and the pinch rollers 26, 27 make the form 100 tense. Thus, it is possible to prevent the form becoming loose and obtain stable line feed accuracy.
