Title: Electrolyte supply structure in matrix-type fuel cell
Inventor: HARASHIMA KOUICHI
IPC: H01M8/02
Filed: 1984-06-06
Abstract: PURPOSE:To smoothly supply an electrolyte by providing an electrolyte supply path which penetrates the matric layers in the direction in which they are stacked and packing the supply path with a material having air holes larger than the air holes of the matrix layers. CONSTITUTION:After unit cells each consisting of a fuel electrode 2, an oxidant electrode 3, a matrix layer 1 and rib electrode base plates 4 and 5 are stacked with separators 6 interposed, cooling plates 17 are installed over and under the stack, thereby making a cell stack for a fuel cell. Between the cooling plates 17, an electrolyte supply path 16 is installed which penetrates the matrix layers 1, the rib electrode base plates 4 and 5 and sealing members 10 in the direction in which they are stacked. And, the path 16 is packed with a material 14 consisting of a mixture of a Teflon resin powder and a silicon carbide powder which has air holes larger than the air holes of the matrix layers 1. Consequently, it is possible to smoothly supply an electrolyte to the matrix layers 1 by capillarity without installing a supply tube for each unit cell.

Title: Driving of variable speed hydrauric rotary machine
Inventor: KIKUCHI KEIZOU
IPC: F03B15/06
Filed: 1981-07-23
Abstract: PURPOSE:To make it possible to drive a variable speed hydraulic rotary machine such as, for example, a pump with a fixed efficiency and an uniform performance irrespective of variations of water head, by driving the variable speed hydraulic rotary machine at a speed proportional to the square root of the mean value of water head which is determined by the condition of water level. CONSTITUTION:A signal converter 6 delivers a rotational speed signal which varies in proportion to the square root of a water head signal indicating a water head H that is determined by the condition of water level for the water turbine of a pump. The rotational speed signal is delivered to a rotational speed controller 7 such as, for example, a cyclone converter which converts the signal into a signal having a frequency corresponding to a rotational speed with which the rotary machine is to be driven. The rotational speed of a generator motor 8 is controlled by the frequency, and the open degree of guide vanes in the pump turbine 10 is controlled by the above-mentioned rotational speed signal through a pump turbine governor 9.

Abstract: PURPOSE:To supply seedlings one by one to a transplanting means, by pushing out seedlings in a lateral line from a seedling box by a seedling pushing means, catching the seedlings by a seedling receiving tool and sending the seedling receiving tool to the lateral direction. CONSTITUTION:When a seedling box 40 is inserted into a seedling box guide base 29 of a seedling box sending means 9 and intermittently sent downward, each lateral line of seedlings 25 is pushed out from the seedling box 40 by a projecting action of a pushing rod 41 while opposing the pushing rod 41 of a seedling pushing means 10. The pushed several seedlings 25 in a lateral line are immediately caught by a seedling receiving tool 20 of a seedling sending means 11. The seedling receiving means 20 is endlessly arranged and intermittently transferred to the lateral direction. When the seedling receiving tool reaches a seedling supplying means, the seedlings 25 on the seedling receiving tool 20 are dropped one by one by the seedling receiving tool 20 and fed to a transplanting means 12.

Inventor: IGUNAATSU FUOOGERU
IPC: F16C29/04
Filed: 1981-07-27
Abstract: A slide track structure for supporting a passenger seat consists of a U-shaped track disposed completely within a square tube supported on the track by balls arranged in the U-track between waved guide strips mounted opposite each other on the track and the square tube and forming a channel receiving the balls. At least one of the guide strips is resiliently supported to bias the square tube so as to cause engagement of the flat adjacent surfaces of the U-track and the square tube when no load is carried by the track. The track is mounted on support bases projecting through slots in the square tube to permit movement of the square tube relative to the U-track.

Title: Inter-frame encoding system
Inventor: KURODA HIDEO
IPC: H04L1/00
Filed: 1980-08-25
Abstract: PURPOSE:To get rid of influence by a code error without transmitting a true value of a picture element, by setting the contents of both frame memories at the transmission and receiving sides, to the same prescribed value, in case a code error has been detected by a code error detecting circuit provided at the receiving side. CONSTITUTION:A code error detecting circuit 100 detects whether a code errier exists or not in a digital signal sequence which is inputted through a digital signal input terminal 10, and sends out its detection signal to the transmission side. As a result, the transmission side executes the inter-frame encoding, setting the contents of a frame memory 5 to a prescribed value, in the next 1 period, and applies a frame memory setting signal to the head of an encoding data of this 1 frame, and sends it out to the receiving side. When it is detected by an output stage of a buffer memory 11 that this frame memory setting signal has been received, the receiving side makes the contents of a frame memory 13 of the 1 frame period coincide with those of the frame memory 5.

Title: Production of amorphous metal
Inventor: TACHIKAWA MASAAKI
IPC: B22D11/06
Filed: 1980-08-25
Abstract: PURPOSE: To considerably improve the accuracy of controlling the contact length of a quick cooling roll and molten metal by allowing quick cooling air to contact with the film of the molten metal pulled up to the revolving circumferential surface of a pickup roll.  
     CONSTITUTION: Part of the circumferential surface of a pickup roll 3 is immersed in the molten metal 2 in a filling vessel 1, and the roll 3 is revolved to pull up the moltem metal 2 in a manner as to wind up the same, thereby forming a thin molten metal film 2'. If the surface condition and peripheral speed of the roll 3 and the viscosity and others of the molten metal are made constant, the thickness of this molten metal film 2' hardly fluctuates despite the occurrence of some fluctuation in the contact length. Thence, a quick cooling roll 4 is allowed to contact with the film 2' to quickly cool and solidify the molten metal, whereby amorphous metal is obtained. Since the position relating control of the roll 4 in contact with the film 2' is the mechanical position relating control of the roll 3 and the 4, the control is extremely easy.
