Patent JP-H04176087-A (JP)
Title: Semiconductor memory device
Inventor: HATTORI KOJI
IPC: G11C11/401
Filed: 1990-11-07
Abstract: PURPOSE:To suppress the increase in chip area and to decrease current consumption to the utmost by providing a plurality of memory cells which are connected to bit lines, a sense amplifier for differentially amplifying the potential difference between the bit lines, and switches for dividing the bit lines. CONSTITUTION:A memory cell 1a (or 1b) which is located on the side of a sense amplifier 5 from a signal line 6 is selected. When the potential of a word line 2a (or 2b) is 'H' and the potentials of other word lines 2a or 2b and 2c and 2d are 'L', the voltage of the signal line 6 is made to be 'L'. Then, MOS transistors 4a and 4b become non-conductive. One half of bit lines 3a and 3b is separated from the sense amplifier. Therefore, the charging and discharging currents can be decreased to about 1/2. When the opposite side of the sense amplifier 5 is used, the switches 4a and 4b are turned ON, and the total charging and discharging current when all memory cells are accessed can be decreased to about 3/4. Thus, the increase in chip area is suppressed utmost, and the charging and discharging currents of the bit lines can be decreased.

Title: Wall panel, manufacture of wall panel and constructing method of wall
Inventor: FUKUSHIMA SHOGO
IPC: E04B2/00
Filed: 1998-10-26
Abstract: PROBLEM TO BE SOLVED: To correspond to a large number of latent demands to a mud wall maximally by providing a wall panel being simply manufactured and executed. SOLUTION: In the wall panel, a bamboo lattice 24 is arranged on the inside of a frame body 22, and the wall panel has a wall body 26 comprising a primer layer 34, a middle coating layer 36 and a finish coating layer 38 as a surface so that the bamboo lattice 24 is incorporated. Since obsidian perlite is mixed with wall materials forming the primer layer 34 and the middle coating layer 36, the wall body 26 has light weight. Since the wall panel is produced in a factory, a special expert (a plasterer or the like) is not required, and manufacturing cost can be reduced.  Since the wall panel is carried in a field and the wall is completed only by installing the wall panel between columns, the kneading works of wall clay and the dry period of the finish-coated wall on an execution field are made unnecessary, and the lengthening of the execution period can be avoided and construction cost can also be reduced.

Abstract: PURPOSE:To secure a turning characteristic conformed to working conditions by constituting a car that it turns so sharply in a small radius at front-wheel speed increasing and rear-wheel one-side braking in time of selecting an automatic brake mode, and in time of the aforesaid releasing mode, it turns so as not to do damage to a surface of the ground at the front-wheel speed increasing alone. CONSTITUTION:Suppose an automatic brake mode is selected by the operation of a mode selector mechanism 50 and a steering operation on front wheels 1 is carried out by a steering mechanism 21 in this state intact, if so, a front-wheel gear shifter 7 comes to a state of being speeded up by each action of the cam mechanism 23 and both first and second linking mechanisms 25, 29, and simultaneously a side brake 27 of a rear wheel 2 at the turning center side is braked, and thereby the turning is performed in a small radius. If the front wheels 1 are steered by the mode selector mechanism 50 in a state that an automatic brake releasing mode is selected, the front- wheel gear shifter 7 is speeded up by the cam mechanism 23 and the first linking mechanism 25, but the side brake 27 will not work at all. In addition, at the time of high-speed running, the mode selector mechanism 50 is automatically turned to the automatic brake releasing mode by dint of energizing force of a checking mechanism 60, so that any small turn is obviated.

Title: Fuse
Inventor: MIYAZAWA TAKAYUKI
IPC: H01H85/045
Filed: 1987-12-01
Abstract: PURPOSE:To protect a circuit such as a winding of a motor, as well as to let flow securely a current necessary for a motor circuit and an incandescent lamp circuit to which a large current flows instantly when the circuit is turned on, by applying a magnetic field to a straight line part of a coil wound to surround the straight line part of a lead wire to try to convert the critical current value. CONSTITUTION:Inside an insulating tube 2, is filled an arc extinguish sand 4 to function to cut off the current flow between electrodes 3 and 3' perfectly by absorbing the molten substance when a lead wire 5 made of a superconductive material is molten. When a current flows through the lead wire 5 of a fuse 1, a magnetic field is generated around the coil 5b of the lead wire 5. The influence of the magnetic field is received by a straight line part 5a surrounded by the coil 5b of the lead wire 5, and the critical current density is reduced. When the density of the current flow through the lead wire 5 is reduced and reaches the critical current density, the lead wire 5 is converted from a superconductive condition to a normal conductive condition, an electric resistance is generated in the lead wire 5, and the current is reduced. When the current is reduced and the density of the current flow through the lead wire 5 comes to be less than the critical current density, the lead wife 5 is converted from the normal conductive condition to the superconductive condition, and the electric resistance of the lead wire 5 is turned to zero.
