Title: Flame-resisting grout for binding rock bed
Inventor: KADOWAKI TAKASHI
IPC: E02D3/12
Filed: 1992-05-26
Abstract: PURPOSE:To obtain a grout to be poured into soft ground to strengthen it. CONSTITUTION:This grout comprises a pack which is a slurry mainly consisting of a finely powdered cement having a powderiness of 5000cm<2>/g or above or a maximum particle diameter of 40mum or below and a urethane formation catalyst and a pack mainly consisting of an isocyanate. This grout is advantageous in, for example, that because the cured product formed when it is used is based on the fine powdery cement which is inorganic and very flame-resistant, it is not burnt by catching the fire even when an underground fire breaks out, that the reaction is very rapid since it is a urethane formation reaction, and the pouring work can be readily done and is quite the same as the urethane process, that it can give a fire-resistant cured product while it retains the merits of a urethane grout, and that it is economically feasible because more than half of the grout comprises an aqueous solution of fine powdery cement, and therefore its cost is markedly lower than that of a urethane grout.

Title: Semiconductor device
Inventor: MURANAKA KIYOHIKO
IPC: H01L23/52
Filed: 1992-05-25
Abstract: PURPOSE:To block corrosion of upper wiring layer from spreading through a through hole part into a lower wiring layer by plugging the through hole part with a bonding wire and electrically conducting the upper and lower wiring layers through the bonding wire. CONSTITUTION:Ball 1a of a bonding wire 1 is bonded through a through hole part 7 to a lower wiring layer 5. The through hole part 7 is plugged with the ball 1a of the bonding wire 1 while upper and lower wiring layers 3, 5 are conducted electrically through the bonding wire 1. Since the wiring layers are isolated vertically and the through hole part for conducting the upper and lower wiring layers is plugged with the bonding wire, corrosion of upper wiring layer 3 is blocked from spreading to the lower wiring layer thus preventing deterioration of characteristics.

Title: Oxide superconductor coil and manufacture thereof
Inventor: TAKEDA YUKIO
IPC: H01B13/00
Filed: 1987-06-26
Abstract: PURPOSE:To form a small-sized and light coil easily by a method wherein a coil of an oxide superconductor is formed collectively on a substrate composed of glass, a ceramic or a metal by using a paste composed of powder of the oxide superconductor and an organic binder. CONSTITUTION:A paste composed of a powder of an oxide superconductor and an organic binder is screen-printed on a glass substrate, a ceramic substrate or a metal substrate to be a form of a coil. The organic binder contained in the paste is heated in the air or in an atmosphere of oxygen. After the binder has been removed by oxidation or thermal decomposition due to the heating, the oxide powder of the oxide superconductor is heated in the air or in the atmosphere of oxygen up to a temperature at which the powder is sintered; by this process, the coil composed of the oxide superconductor is formed collectively on the substrate. In addition, if two or more glass or ceramic sintered substance or metal substrates on which the coil has been formed in the above manner are laminated, a multilayered coil can be formed.

Title: Battery lock spring device for telephone set
Inventor: HARADA YOSHINORI
IPC: H04W88/02
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To facilitate attachment/detachment operation without the need for a large force in the case of attaching/detaching a battery pack by adopting an S-shaped spring from a conventional Ushaped spring so as to strengthen the initial pressure thereby obtaining sufficiently a holding force. SOLUTION: A battery pack 2 has an upper case 2a and a lower case 2b to contain a battery. A lock lever 3 provided turnably around a support 4 toward the battery pack 2 has a projection 6 engaged with a recessed part 5 provided to a telephone set main body 1. A spring 8 always energizes the lock lever 3 in the direction that the projection 6 engages with the recessed part 5. The S-shaped spring 8 is adopted. Thus, in the S characteristic of a weight with respect to the displacement of the clock lever, the initial pressure is high and in the case attaching/detaching the battery pack 2, the same force as the conventional U-shaped spring is enough. Thus, the operating range of the weight is narrower than that of the case with the U-shaped spring and while improving the attachment/detachment operability of the battery pack 2, the holding force is strengthened.

Title: Camera capable of magnetically recording
Inventor: ITO JUNICHI
IPC: G03B17/00
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To record data with a desired recording density, even if the resolution of a detecting means for detecting a film speed is changed by correcting the space values of pulse signals generated whenever a film is moved by a specific amount. SOLUTION: Whenever the film 9 is moved for the specific amount, a pulse generating part 1 generates the pulse signals and outputs them to a microcomputer 10. A pulse width measuring part 2 measures the spaces of the pulse signals. A correcting part 3 corrects the time interval data of the measured pulse signals by using the correction data of an EEPROM 8. Time data required for recording the data with a reference recording density and a bit location is read from the table of a data table part 4, based on the corrected data and set in a timing generating part 5. A magnetic head driving part 6 causes a current to flow in a magnetic head 7, in synchronization with the output of the timing generating part 5. Thus, the data is recorded on the magnetic recording layer of the film 9.

Title: Booster circuit
Inventor: KONO KENJI
IPC: H02M3/07
Filed: 1994-07-11
Abstract: PURPOSE:To provide a booster circuit in which the loss is reduced through simple circuitry by controlling the switching of series and parallel connection of a plurality of capacitors charged with high voltage using only a low voltage clock signal. CONSTITUTION:Capacitors 31-33 are charged in parallel by turning NMOS transistors 41-43 ON and turning PMOS transistors 51-53 OFF. When the NMOS transistors 41-43 are then turned OFF and the PMOS transistors 53 is turned ON, a power supply voltage VCC appears at a joint 76 and the voltage at a joint 73 is boosted to the sum of the voltage of the capacitor 33 and the power supply voltage VCC. Since the gate voltage of the PMOS transistors 52 drops below the source voltage thereof, the PMOS transistor is turned ON and the PMOS transistor 51 is also turned ON to connect the capacitors 31, 32, 33 in series. Consequently, high voltage at the joint 71 can be obtained from an output terminal 62 through a rectifying circuit 61.

Abstract: PROBLEM TO BE SOLVED: To form an alignment key pattern even in a trench remote structure by forming a first insulation film pattern for limiting the field region of a cell array and an alignment key pattern and forming a second insulation film while filling a trench. SOLUTION: A first insulation film pattern 32 is formed on a semiconductor substrate 31 to limit a field region. Then, the entire surface of the semiconductor substrate 31 is subjected to anisotropic etching with the first insulation film pattern 32 as an etching mask and a trench 34 with a specific depth is formed at a field region. A second insulation film 36 is formed on the entire surface while filling the trench 34. In this case, since the trench width formed at a cell array region is much narrower than a trench width formed at a peripheral circuit region so that the level difference between an active region at the cell array region and the field region can be minimized. However, a trench with a much wider trench can be formed at an alignment key pattern region while maintaining the level difference.
