Abstract: PURPOSE:To obtain a solar battery which has excellent photoelectric conversion characteristics, hardly creates defects and shows little light deterioration by a method wherein, among a P-type layer, an N-type layer and an intermediate layer, at least the intermediate layer is composed of a super-lattice structure and the part of an electron distribution and the part of a positive-hole distribution are spatially separated. CONSTITUTION:A transparent conductive film TCO made of SnO2, ITO or the like is formed on a glass substrate 1 and electric power generated by a solar cell is taken out through the transparent conductive film TCO and a backside electrode 5. A P-type layer 2 is, for instance, composed of a semiconductor layer made of P-type amorphous SiC and an N-type layer 3 is composed of a semiconductor layer made of N-type amorphous Si and an intermediate layer 4 is composed of a doped super-lattice composed of a structure of (P<->-I-N<->-P-I-P<->-...). More concretely, 20-30 cycles of the cycle unit composed of a P<->type layer, an I-type layer, an N<->type layer and an I-type layer whose thicknesses are approximately 50Angstrom  each are laminated to form the super-lattice structure. The thickness of each layer can be varied in the range from several angstroms to several hundreds of angstroms and, by controlling those thicknesses and changing the cycle, spatial distance between the distributions of electrons and positive holes can be increased or decreased and the two distributions can be separated.

IPC: B60N2/90
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To prevent a driver from having interference with driving resulting from difficult seating caused by breakage of a seat even if rapid stopping causes rear load to collide with a seatback frame. SOLUTION: A seatback frame 10 is constituted so that the upper and lower parts of a pair of right and left side members 11 may be connected by an upper member 18 and a lower member 19. The respective side members 11 are constituted of slender main plate parts 12 parallel to a central surface, front side plate parts 13 and rear side plate parts 14 which are connected along roughly the whole length of its front edge and rear edge, and are extended at a right angle from the main plate parts 12 in the same direction, and front part reinforcing plate parts 15 which are connected along roughly the whole length of the vicinity of the front edge, and are extended in the opposite direction to the front side plate parts 13, and the side members 11, the upper member 18, and the lower member 19 are formed integrally with metallic material with adequate breaking elongation. It is thus possible to absorb impact energy caused by load collision from rearwards by the distortion of the rear side plate parts 14 and the main plate parts 12 in the vicinity of a collision part.

Title: Wiper blade
Inventor: SAWARA HIDESHI
IPC: B60S1/38
Filed: 1998-01-19
Abstract: PROBLEM TO BE SOLVED: To provide a wiper blade capable of reducing the number of parts and assembly man-hour so as to reduce cost, providing a sealing capability (waterproof) while preventing the connection parts of each lever from playing, and preventing the connection parts of each lever from being soaked with water or frozen so as to maintain a follow-up capability in order to prevent a wiping performance from being lowered. SOLUTION: A wiper blade 10 is structured so that O-rings are installed on a connection part 32 for connecting a primary lever 12, secondary levers 14 and 16, and yoke levers 18 and 20 to each other with a pivot shaft. These O-rings tightly press the opposed faces of each lever, and shield the surroundings of the pivot shaft from the outside. The connection part 32 of each lever is prevented from playing, thus eliminating noise from occurring during wiping. In addition, an entry of water drips into the connection part 32 is prevented, thus eliminating a reduction in follow-up capability to a glass surface due to freezing so as to assure an excellent wiping capability.
Patent JP-H02224059-A (JP)
Title: Character processor
Inventor: MASAKI KATSUMI
IPC: G06F17/21
Filed: 1990-01-16
Abstract: PURPOSE:To output plural character patterns with high quality, based on plural kinds of pitch controls by outputting plural desired character-strings in accordance with a derived character interval without exerting the influence on other character-string except a desired character-string. CONSTITUTION:When a forbidden key is depressed, forbidden characters existing in a line end and a line head are all excluded from its position. As a result, the character-string becomes a form into which a forbidden code is inserted. When it is tried to execute an insertion or a deletion to the character-string which becomes such a form once, a special processing is executed with respect to the forbidden code. That is, in the case of the insertion, the forbidden code is decreased by the character-string existing in front of its code. Also, in the case of the deletion, the forbidden code increases. In such a way, a fact that the character-string which is brought to forbidden processing once is placed against forbiddance again is prevented to the minimum.

Title: Asymmetrical rolling mill
Inventor: YAMADA SEIICHI
IPC: B21B13/14
Filed: 1978-01-25
Abstract: PURPOSE:To make shape better by symmetrizing the distribution of load and by levelling metal to be rolled by the method in which any of rolls for rolling is made into a large diameter for its one end and also into a small diameter for its another end the roll diameter is gradually made smaller from the one end to another. CONSTITUTION:In the case of rolling, operation is made by the intermediate upper and lower rolls 3 and 4 toward the axial direction to the position at which the point 0 is centered. When a load is applied to asymmetrical rolling mill by the pressure lowering device 7, all of the intermediate upper and lower rolls 3 and 4 are deformed (continuous line), where the upper and lower spare rolls 5 and 6 and the upper and lower operation rolls 1 and 2 are thus drformed, but the left side of the intermediate upper roll 3 becomes smaller than the right side, differently from the conventional case in which the left side is larger than the right side. The same is true of the lower operation roll 4. Thus, by arranging the main roll, the inclination of the axial line of the intermediate rolls and operation rolls is eliminated and the metal to be rolled is made horizontal.

Abstract: PROBLEM TO BE SOLVED: To provide a computer system in which security can be improved without forcing the load of attention to a user. SOLUTION: An encipherment algorithm is decided for each operator, and a file for storing a file to which access is permitted to each operator is enciphered and stored in an outside storage device 4. At the time of activation, the picture of the fingerprint of the operator is read by a fingerprint reading device 1. A control part 6 specifies the operator from the picture of the fingerprint of the user, and allows corresponding encipherment and decipherment programs to be resident in a main memory. Afterwards, it is possible to perform access to the file which can be deciphered by the resident decipherment program. The files of others are enciphered by different encipherment algorithms so that access can be inhibited.

Title: Automatic cooling equipment
Inventor: TAKE MASAFUMI
IPC: G01N25/00
Filed: 1993-01-21
Abstract: PURPOSE:To give a heating furnace a refrigerant being free from pulsation and to attain reduction of consumption of liquid nitrogen and stabilization of the temperature of the heating furnace by controlling a heater by a phase signal outputted from a heater power computing circuit. CONSTITUTION:A heater power computing circuit 1 receives the temperature of a heating furnace and the target temperature of the heating furnace as inputs, calculates a power to be applied to a heater, converts the value of the power into a phase and gives this onto one side of a comparator 2. When a reset signal from a sync pulse generating circuit 3 is canceled at the time point when an AC power source turns to be at 0V and enters the next cycle, an integrating circuit 4 integrates clocks from a clock generating circuit 5 and gives the result onto the other side of the comparator. Comparing these two inputs, the comparator 2 turns a thyristor 6 ON at the time point when the inputs coincide with each other, and the power is given to the heater. When an AC voltage comes to the vicinity of 0V, the sync pulse generating circuit 3 resets the integrating circuit 4 and the AC power source enters the next cycle. This operation is repeated and the heater is controlled by a phase control.
