Title: Paste-type lead storage battery
Inventor: TSUBOTA MASANAO
IPC: H01M50/437
Filed: 1979-08-11
Abstract: PURPOSE:To obtain a long-life lead storage battery with less reduction of the pressing degree of elements by using a glass mat obtained by pressing glass fibers of a specific size and an apparent density of more than a value when pressed under a specific pressure. CONSTITUTION:An element consisting of glass mats composed of glass fibers 10mum or more in diameter, having an apparaent density of 0.18g/cm<3> or more when pressed under a pressure of 20kg/dm<2>, is pressed to form a storage battery. In this case, 1% or less a binder, e.g., starch, gelatin, a synthetic resin, etc., is used in the glass mats. Thus, a long-life lead storage battery in which the active substance of the electrode plate is less fallen can be obtained because of the use of the glass mats whose thickness is less reduced when dipped in electrolyte and those pressing degree is thus less lowered.

Consequently, electron leaked from the active layer (b) are confined to the layer (d) by an adjacent layer (e), light with the same wavelength as the layer (b) can be generated, luminous energy increases and light emitting efficiency is improved.

The callus generated from the scutellum is alone taken out from the cultured product and subsequently subcultured in a medium containing alpha-cyclodextrin, beta-dextrin or gamma-dextrin. The adventitious bud is induced from the subcultured callus in the same medium and then redifferentiated into young plant bodies, which are grown into seedlings to efficiently provide the rice plant bodies whose callus was multiplied in a low auxin concentration, whose reproducing ability was enhanced at the young plant body-redifferentiation stage and whose rooting rate was enhanced at the seedling-producing stage.

Title: Recorder with ae function
Inventor: GOTO TOMOYUKI
IPC: G03G15/00
Filed: 1988-04-26
Abstract: PURPOSE:To arbitrarily select either a high quality image or high productivity by switching two modes, 'prescan' and 'no prescan'. CONSTITUTION:When the mode 'prescan' is selected by AE (automatic exposure) mode switching means 001, a first AE scanning is carried out at the timing detected by an optical system operation-timing control means 003. The electric potential of a latent image is detected, so that light quantity is controlled, and also developing bias is controlled, so that a copy is scanned. The light quantity is then returned to AE scanning, whereupon copying is performed successively. In the selection of the mode 'no prescan', background electric potential is read at the minimum value of surface electric potential used in copy scanning, and based on that value the developing bias is controlled. Thus, high quality in 'prescan' and high productivity in 'no prescan' are obtained.

Abstract: PURPOSE:To prevent a surge absorbing element from being formed owing to successively occurring overvoltage by providing a heat-shrinkable insulating tube for fusing a low melting point metal element by shrinking said tube by heating of the surge absorbing element. CONSTITUTION:A title absorber comprises a surge absorbing element 21a, a low melting point metal element 22 electrically connected in series to said surge absorbing element 21a, and a heat-shrinkable insulating tube 25 for covering therewith the surface of the surge absorbing element 21a and the low melting point metal element 22 such that they make close contact with each other and fusing the low melting point metal element 22 by shrinking the tube 25 by heating of the surge absorbing element 21a. Accordingly, a successive overcurrent is driven to flow through the surge absorbing element 21a to overheat the element 21a and hence fuse the low melting point metal element 22. And successively, the heat-shrinkable insulating tube 25 is shrunk to fuse the low melting point metal element 22. Additionally, the heat-shrinkable insulating tube 25 as an insulator enters the low melting point metal element 22 to completely block the overcurrent.

Abstract: PURPOSE:To prevent the deterioration of conductivity by molding a conductive sheet made of conductive fibers covered with a low-melting point metal on the surface and thermoplastic resin at the temperature higher than the melting point temperature of the low-melting point metal. CONSTITUTION:A conductive sheet 3 made of conductive fibers 1 covered with a low-melting point metal 2 on the surface and thermoplastic resin is molded at the temperature higher than the melting point temperature of the low-melting point metal. For the conductive fiber 1, the organic fiber having a metal layer such as copper fiber, copper alloy fiber or the inorganic fiber or the like may be used, and they are used independently or two or more kinds are mixed for use. For the low-melting point metal 2, metals with the melting point nearly equal to or higher than the molding temperature of the thermoplastic resin are preferable, e.g., a general solder alloy mainly consisting of Sn or Sn-Pb, a high-temperature solder alloy mainly consisting of Sn-Pb-Cd-Ag-Zn, or the like.

Abstract: PURPOSE:To prevent malfunction due to a stray current during the starting of an opposite station booster, by providing an inhibiting circuit which suppresses reverse signal detection while opposite station starting pulses are sent during the starting of the opposite station booster. CONSTITUTION:To strat an opposite station with a booster voltage VB through a junction line trunk LSV1, a one-wire starting circuit ST1 is put in operation and thus a booster voltage VB is applied via a route B1 A0. A reverse detection preventing circuit PRT which inhibits a reverse detection signal while a start control signal ST is sent out is provided, and only when the opposite station grounds the point A0 and applies a battery voltage to a point B0 like a connection confirmation signal and an answer signal, a reverse detecting circuit RVD1 operates by a current flowing via a route A0 B1 b1 c2 L3  og2  RVP1 L2 C1 A1 A1 B0, thereby sending a gate signal to the preventing circuit PRT. As a result, a reverse signal is extracted at RV. Therefore, malfunction is prevented by the start signal through the circuit PRT.

Filed: 1988-04-28
Abstract: PURPOSE:To prevent the excessive compression of a packing material and to control a decrease in the collecting performance after operation is resumed by deforming the impurity collecting packing material when a drag at higher than a specified value is exerted on the material by a liq. metal to form a bypass passage. CONSTITUTION:When a specified amt. of impurities is collected by the impurity collecting packing material 4 and a drag exerted on the material by the liq. metal is increased, the upper part of the material 4 contg. no reinforcing rings 9 is bent inward, and a gap is formed between the material 4 and the upper baffle plate 3. As a result, the liq. metal is bypassed and allowed to flow through the gap, hence the draft of the liq. metal exerted on the material 4 is not excessively increased, and the excessive compression of the material 4 can be prevented. Accordingly, the impurities are drained and operation is resumed, and the material 4 is kept in the state almost equivalent to that of the initial operation.
