Title: Melt-spinning of pitch-base carbon fiber and spinning nozzle therefor
Inventor: SHIMOSAKO TOSHIYA
IPC: D01D4/04
Filed: 1988-09-10
Abstract: PURPOSE:To stably prevent the troubles such as fiber breakage over a long period by using a material non-wettable with molten pitch at the surface of the opening part of the spinning nozzle main body and melt-spinning a spinning pitch containing an optically anisotropic phase through the spinning nozzle. CONSTITUTION:The surface of an opening part of a spinning nozzle main body 1 is coated with a material non-wettable with molten pitch (e.g., titanium nitride, titanium oxide or alumina) to form a coating layer 2. A carbon pitch for spinning preferably containing %i50vol.% of optically anisotropic phase is melt-spun through the spinning nozzle and subjected to infusibilization and carbonization treatment to stably obtain the objective high-performance carbon fiber preventing the contamination near the spinning nozzle and suppressing the generation of kneeling.

Title: Semiconductor memory
Inventor: KATO YASUSHI
IPC: G11C17/00
Filed: 1990-08-28
Abstract: PURPOSE:To shorten the time required for a function check of a decoder by providing a second memory cell array which is connected to plural word lines and does not take part in storage of information, and mixing and placing a conduction type transistor and a non-conduction type transistor in this memory cell array. CONSTITUTION:At the time of test mode, when an output signal (x) of a test signal generating circuit 109 becomes an H level, all decoding lines (a), (b), (c) and (d) of a Y decoder 302 become an L level. In this case, N channel transistors TR N1, N2, N3 and N4 are all turned off. On the other hand, an N channel TR N17 is turned on, when the signal is an H level. Accordingly, digit lines d1, d2, d3 and d4 connected to a memory cell array 307 are all cut off, only a (y) signal of the digit line of a decoder check cell array supplies a signal to a read-out circuit 106, and this signal is outputted to the outside from an I/O terminal I/O through an I/O buffer 305.

Title: Sealed lead-acid battery
Inventor: MATSUMARU YUUJI
IPC: H01M10/06
Filed: 1983-11-30
Abstract: PURPOSE:To obtain a battery whose charge-discharge life is good and cost is low by maintaining ion conductive connection of one or both of positive and negative active materials and a separator by silicate colloids. CONSTITUTION:Assembly pressure of a separator and a plate is reduced to 0 (no pressure)-10kg/dm<2> from, for example, 20kg/dm<2> of conventional assembly pressure. Thereby, apparent pore size of a void 4 which is formed by contact of, for example, glass fiber constituting a separator 3 and a positive plate 1 or a negative plate 2 is increased than that of the separator. Silica fine powder in electrolyte preferntially enters the void 4 and ion conductive connection of the separator and active material is maintained by colloidal electrolyte in the void 4. The voids 4 are formed on almost all surface of the plate and silica fine powder penetrates easily to give the same effect as decreased pore size of the separator. Layer formation caused by falling down of sulfate through the separator is prevented.

Whether speed change gear stage regulation control is required or not is then determined from a map. and whether this area needs speed change stage gear regulation control or not is determined. In case of judging the necessity of control and further in case of judging the necessity of secondary judgment, the set area is divided in two areas, and average curvature and an average gradient are obtained on each specific divided area.  In case of judging the necessity of speed change stage gear regulation control, a change gear ration is set within a determined regulation range.

Filed: 1987-09-14
Abstract: PURPOSE:To shorten the loss time, and to execute the information processing at high speed by executing an alternate processing against an information defect of one face, to an alternate area provided on the other face. CONSTITUTION:At the time of recording the information to an information recording medium 101 having a recording surface on at least the back face and the surface, respectively, an alternate processing against an information defect of one face is executed to an alternate area 102 provided on the other face. Accordingly, for instance, when the surface defect is generated on a part of the recording surface of the surface side, information is not recorded in an area containing this defect, and immediately the information is recorded in the alternate area 102 provided on the recording surface of the back face. In such a way, a loss time which follows up the movement of a head at the time of alternate processing is shortened, and the information processing can be executed at high speed by that portion.

Title: Water level detecting device
Inventor: SAITOU FUMIYOSHI
IPC: G01F23/60
Filed: 1997-08-26
Abstract: PROBLEM TO BE SOLVED: To make the water level in a protective container to smoothly rise, following the rise of the water level in a tank. SOLUTION: An attaching recessed section 25 is formed on a lid body 8 put on a water tank 2 and a protective tube 27, having a communicating port 2 formed through its lower end face, is provided on the bottom of the section 25. Float switches 31 and 32 are positioned in the tube 27, and an air vent hole 40 is formed through the upper end section of the peripheral wall of a tube 28. When fresh water is supplied to the tank 2, the water level in the tank 2 rises and, at the same time, the water flows into the tube 28. When the water flows in the tube 28, the water level in the tube 28 rises smoothly as the air above the water surface in the tube 28 goes out through the air vent hole 40.  Therefore, the water level in the tank 2 can be detected precisely, because the water level in the protective tube 28 in which the float switches 31 and 32 are positioned rises accurately following the water level in the tank 2.
