Title: Connector
Inventor: HIRAI HIROKI
IPC: H01R13/58
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To enable a connector to be easily manufactured with a small number of parts by providing a shell insertion groove and a shield member in a space in which a coupling part is not provided between an inside housing and an outside housing. SOLUTION: A connector housing 10 is entirely formed of an insulating material and is made of a cylindrical inside part (inside housing) 12 and an outside part (outside housing) 13. The inside of the inside housing 12 is a terminal housing chamber 11 for housing a male terminal, and a lance 12a is provided on an interior wall of this terminal housing chamber 11, and the male terminal is locked. The inside part 12 and the outside part 13 are coupled with each other partly in peripheral direction by a pair of coupling parts 14, and a shell insertion groove 15 is ensured between the inside and outside parts 12 and 13 at a part other than the coupling part 14.

Title: Driving method for liquid crystal display device
Inventor: HANAZAWA YASUYUKI
IPC: G02F1/136
Filed: 1997-04-09
Abstract: PROBLEM TO BE SOLVED: To suppress crosstalks independent of variation of a displayed pattern and to display a clear image with high contrast by deviating a phase between a video signal and an opposed electrode signal by a period of one half of a selection pulse applying period. SOLUTION: A driving circuit 16y applies a selection pulse sent from a shift register 21 to scanning lines 14a, 14b through a buffer 22. Timing of signal voltage applied to signal lines 13a-13d and gate voltage applied to scanning lines 14a-14b are same as conventional timing, but reversed timing of counter electrode voltage applied to counter electrodes through a common voltage adjusting circuit 17 is delayed by an amount corresponding to a period of approximately one half of one horizontal scanning period from timing at which a polarity of signal voltage is reversed. Therefore, an effective value of voltage applied to a non-pixel part can be kept approximately constant independently of a pattern displayed on a display section 10, degradation of picture quality caused by cross talk can be reduced.

Title: Manufacture of high-strength dust core
Inventor: ASAKA KAZUO
IPC: H01F1/26
Filed: 1984-05-08
Abstract: PURPOSE:To obtain a high-strength compressed powder core by specifying the compressed powder density of a dust material in terms of density ratio, and employing a lubricant having a melting point higher than the setting temperature of a resin. CONSTITUTION:When the melting point of the lubricant is lower than the setting temperature of the resin, the lubricant melts in the course of setting of the resin, thereby obstructing the required bonding to be obtained between the iron powder and the resin and also the formation of an excellent resin layer, which leads to a lowering in strength of the product. Therefore, the compressed powder density of the dust material is specified so as to be 82% or more by density ratio, and a lubricant having a melting point higher than the setting temperature of the resin is employed. Thus, it is possible to obtain a dust core having high magnetic flux density and high strength.

CONSTITUTION:Speed control devices 12 and 13 are provided for a drive motor 7 to drive a pickup roller 2 and another drive motor 11 to drive a carriage conveyor for carrying a picked material. The speed control devices 12 and 13 maintain the speeds of the carriage conveyor and the pickup roller 2 at a low level until the carriage conveyor comes to collide with the edge of the picked material, thereby preventing damage to the material in stored state. On the other hand, the speeds of the pickup roller 2 and the carriage conveyor are selected to a high level after the collision for quickly taking out and transferring the picked material. As a result, even a weak picked material in stored state can be efficiently arranged to suit tier picking.

Title: Air compression type sand box molding machine
Inventor: ARANA ERANA OOSUTEIN
IPC: B22C15/24
Filed: 1990-04-06
Abstract: PURPOSE: To provide a sand mold having a large density and excellent strength by constituting the machine in such a manner that the supply of sand to a solidification chamber is diffusively executed by rotation of vanes, that a motor is fixed onto the supporting plate of a hopper mouth part and that the opening allowing the passage of the falling sand is formed at the plate. CONSTITUTION: The pressure of a boiler is transmitted to the chamber 25 regulated by the rear surfaces of a ring 22 and a plunger 26 and the boiler pressure acts on the top end portion of the plunger 26. The rear surface of the plunger 26 is larger than the contact surface of the two planes of its top end and the front end wall of a passage 17 and, therefore, the boiler pressure acts effectively on the contact portion, by which the closing state of the opening 18 is effectively held. When the communication of the chamber 25 with the outer space of a conduit 30 is resulted, the pressure in the chamber 25 drops sharply and the plunger 26 descends, bringing the opening 18 to an open state. In this state, the air in a manifold 20 is discharged to the surface of the sand packed in the solidifying chamber 4 and the solidification of the sand is effected.

Abstract: PURPOSE:To adjust the level of a logic output as a multi-input logic circuit and to implement the same logic operation while decreasing the number of stages by connecting 1st and 2nd series gate circuits in parallel and clamping the output of the gate circuits with a clamp circuit. CONSTITUTION:A 1st series circuit comprising a bipolar transistor(TR) takes the logic of 3 kinds of input signals C, D, E, and outputs an output V1. The logic V1 is expressed as V1=-(C.D.E). A 2nd series circuit takes logic of input signals A, B and outputs an output V2. The logic is expressed as V2=-(A.B) without a clamp circuit, and the clamp circuit is provided and so long as the output V1 of the 1st gate circuit is not selected, the output V2 is clamped by the clamp circuit and the output V2 is selected to be -0.8V or over. Moreover, since the logic threshold level of the inverter in an inverter group is set to be -1.5V, only the output of a selected gate circuit inverts an output voltage V3 of the inverter.

Title: Developer for photosensitive resin and its developing method
Inventor: SUZUKI YUJI
IPC: G03F7/30
Filed: 1993-04-20
Abstract: PURPOSE:To enable development without discharging environment destroying materials, such as triethane, by constituting the developer of butyl acetate and alcohol of specific number of carbon atoms and specifying the ranged an alcohol concn. CONSTITUTION:The developer consists of the butyl acetate and 1 to 9C alcohol of 33.3 to 75wt.% concn. An acrylic dry film 2 is thermocompression bonded by a laminator on a substrate 1 and is rested until the temp. falls down to room temp. The film is then irradiated with UV rays 4 through mask patterns 3 to form exposed parts 5 and unexposed parts 6; thereafter, the substrate is rested at room temp. This material to be developed is developed by a liquid mixture composed of the butyl acetate and alcohol described above. The mechanism of the development is such that the butyl acetate molecules and the alcohols are solvated and the alcohol molecules are attracted to the circumferences of the butyl acetate molecules by mixing the butyl acetate and the alcohol. The influential power of the butyl acetate on the photosensitive resin is, therefore, relieved by the alcohol molecules and the balance are hardly dissolved.
