Patent JP-H02267973-A (JP)
Title: Thin film solar cell
Inventor: KAWATE KENJI
IPC: H01L31/04
Filed: 1989-04-07
Abstract: PURPOSE:To decrease a recombination of generated carriers and to prevent a reduction in generated output by a method wherein an i-type layer of a p-i-n junction is provided on one side of p-type layers and n-type layers, which are arranged in close vicinity to each other. CONSTITUTION:Layers 2 of p-type amorphous silicon a-Si and n-type amorphous silicon a-Si layers 4 are alternately formed on an insulative substrate 6 through a metallic electrode layer 7, the layer 7 is formed by patterning from an Al or Ag deposited layer and the layers 2 and the layers 4 are formed by patterning respectively from a p-type a-Si layer and an n-type a-Si layer, which are formed on the whole surface of the substrate, at intervals of 5mum or shorter. An i-type a-Si layer 3 is deposited on the whole surfaces of the layers and moreover, the upper part of the layer 3 is covered with a light-transmitting protective film 8 consisting of SiO2 or the like. Incident light enters through the side of the film 8 to reach the layer 3 and carriers are generated. As the intervals between the layers 2 and 4 are respectively 5mum or shorter, the carriers can reach the p-type layers or the n-type layers. In this case, as the areas of a p-i interface and an i-n interface are half or smaller of the area of the i-type layer, a recombination of the carriers due to an interface defect is little. Thereby, a reduction in the output of a solar cell can be prevented.

Abstract: PURPOSE:To improve the services to the customers at occurrence of a fault without duplicating a host computer and a circuit by switching the connection of an automated equipment to an external storage that stores previously the customer information from the host computer when the automated equipment detects a fault. CONSTITUTION:When an automated equipment 2 detects a fault of a circuit which secures the connection between the equipment 2 and a host computer 1 of a center side or a fault of the computer 1, the connection of the equipment 2 is switched to an external storage device 4 that stores previously the customer information from the computer 1. Then the equipment 2 can be operated via the storage device 4. When the fault is restored, the connection of the equipment 2 is switched to the computer 1 from the storage device 4. At the same time, the transaction data stored in the storage device 4 are transferred to the computer 1 and the equipment 2 can be operated again via the computer 1. Thus the services can be improved to the customers at occurrence of a fault without duplicating the computer 1 and a circuit.

Title: Laser diode driving device
Inventor: NANBARA TOMOHIKO
IPC: H01S5/068
Filed: 1989-04-10
Abstract: PURPOSE:To form stable light output through automatic control by supplying a partial pressure value by a thermistor and resistance to input of an error amplification circuit and by controlling a current value of a current source by the output voltage. CONSTITUTION:As for a relationship between a light output level and a current of a laser diode 3, if a driving current exceeds some threshold value, laser oscillation develops and light is output. Here, a bias current IB is set to a value which is slightly lower than the threshold value, and a desired light output can be acquired by superposing a modulation current thereto. If a current source 8 is connected to an output of a current amplification circuit 7 and a current value IO thereof is added, an output current value is controlled to IB+IO in the current amplification circuit 7. In this case, IB tends to increase in proportion to a temperature. Therefore, a load current of the current amplification 7 can be made constant at a proper value for stable operation by providing reverse temperature characteristic to the current source 8.

Abstract: PURPOSE:To prevent a theft of an automobile tire by detecting an inclination of the automobile with good accuracy. CONSTITUTION:When an iron core 3 is fixed on an automobile body, the iron core 3 is inclined in a body with the automobile body. With reference to this, since a movable iron core 1 holds an angle in a pendulum state so as to face in a direction G of the gravity at all times, an angle theta of inclination is generated between both. At this time, when the facing part of the iron cores 1 and 3 is made in a comb shape, the resolution with reference to the angle theta of inclination is improved. Consequently, when the titled inclination sensor is utilized, a system to sound an alarm automatically can be constituted by jacking up and inclining a part of the car body at the time of the theft of the tire.
