Title: Liquid crystal display element
Inventor: NAKAJIMA MITSUO
IPC: G02F1/136
Filed: 1997-03-19
Abstract: PROBLEM TO BE SOLVED: To prevent deterioration in the picture quality of a display screen due to a light leak and to economically actualize excellent display characteristics by providing a light shield layer, where an area producing a specific electric field is arranged covering a substrate surface, for a couple of electrodes which produce specific electric fields in mutually different directions. SOLUTION: The liquid crystal display element has an active layer 101 of TFTs formed of a-Si and a gate electrode line 103 and a pixel electrode 104 via a gate insulating film formed on an in-plane electrode 102. The in-plane electrode line 106 is connected to the in-plane electrode 102 through a contact hole 107. An electric field in one direction between electric fields produced by the pixel electrode 104 and in-plane electrode 102 is cut off by an electrode pattern 110 to limit the rotation of liquid crystal molecules. Therefore, a light leak due to abnormal orientation of liquid crystal molecules resulting from the structure of the in-plane electrode 102 and pixel electrode 104 is prevented to prevent the picture quality of the display screen from deteriorating.

Filed: 1980-05-19
Abstract: PURPOSE:To enable to conduct whitening-signal recording at low frequencies and reduce noise components such as incompletely erased signals by a method wherein a recording medium preliminarily blackened to a saturation level is irradiated with a laser spot beam with a reduced modulation duty to produce a record on the medium. CONSTITUTION:A recording film 3 having such properties that the optical density is increased by gradual heating after heating and is decreased by rapid cooling after heating, it formed on a heat-resistant substrate 2 and it is heat-treated to blacken it to the saturation level, thereby obtaining a black disc 1. In the case of low frequency repetition, the duty of information signals 6 mudulating directly a semiconductor laser 4 is reduced, whereby the surface of disc is exposed to short pulses and the rapid cooling is made possible, so that the white-signal recording can be conducted. When erasing the recorded signals by blackening, the irradiating power is lowered and disc is irradiated with continuous light beam, whereby white bits are blackened and therefore the recorded signals are erased.

Title: Perishable food storage unit
Inventor: FUJIYA JINICHI
IPC: F25D3/00
Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To reduce the facility cost and the running cost by an arrangement wherein a solute supply machine supplies ice and snow with a solute, e.g. salt or calcium chloride, in order to cool a storage unit by lowering the melting point of ice and snow through mol effect and a temperature controller controls temperature in the storage unit to a set level. SOLUTION: Melting point of ice and snow S drops through mol effect when the ice and snow S is melted by adding a solute. For example, the melting point drops down to about -18.6 deg.C when water of 1 litter is added with a solute of 10 mol. The ice and snow S having a melting point lowered by means of the added solute cools down the surroundings to 0 deg.C or below. The solute being added to the ice and snow S includes salt, calcium chloride, magnesium chloride, alcohol, and the like. Since salt and calcium chloride are inexpensive, running cost can be reduced. A temperature control circuit 3 detects temperature in a storage unit 1 and controls the quantity of solute being added to the ice and snow S. The temperature control circuit 3 has a circuit for controlling a solute supply machine 2 based on the output signal from a temperature sensor 4.

Filed: 1999-03-12
Abstract: PROBLEM TO BE SOLVED: To enhance productivity by holding a plurality of pellets on a die stage and bonding those pellets to one or more mounting areas on a substrate at the same time. SOLUTION: A die stage 15 is positioned under a position of bonding work, so that the die stage can be moved up and down and pellets 1 fed are held on a shift head 14. A bonding tool 16 is positioned above the position of bonding work, so that the bonding tool can be moved vertically and the mounting area 3 on a board 2 is pressed against the pellets 1 on the die stage 15 from the underside. Thus the plurality of the pellets 1 are simultaneously thermocompression-bonded to the mounting areas 3 on the substrate 2 via a thermoplastic adhesive tape stuck previously to the underside of the board 2 by heating. As a result, bonding of the pellets is completed with one-time bonding operation and productivity is improved.
