Title: Production of thin-film transistor
Inventor: IKEDA HIROYUKI
IPC: H01L21/268
Filed: 1997-08-22
Abstract: PROBLEM TO BE SOLVED: To produce a thin-film transistor at low cost which can maintain high long-term reliability, without lowering the property. SOLUTION: While an SiOX film 33 is formed on a polycrystalline Si layer 32 for an active layer, an excimer laser beam 34 is applied to the film 33, so as to improve the film quality of the film 33 through heat treatment. The irradiation energy of the excimer laser beam 34 which changes the structure of the layer 32 is higher than that necessary for melting an amorphous Si layer and changing it into a polycrystalline state. Consequently, the excimer laser beam 34 sufficient for melting the amorphous Si layer is applied appropriately thereto, thereby improving the film quality of the film 33 without causing changes in the structrure of the layer 32 for the active layer already formed.

Title: Device for generating solid-state image pickup element driving signal
Inventor: TERADA KENJI
IPC: G06T1/60
Filed: 1990-09-12
Abstract: PURPOSE:To reduce the capacity of a memory by outputting the same address to the memory, since all of the element driving signals are the same against a one-dimensional solid-state image pickup element during an effective picture element period. CONSTITUTION:The 1st address counter 9 inputs a clock 1 and outputs addresses 10 corresponding to the picture elements of a one-dimensional image pickup element. The 1st comparator 11 opens the 1st gate 12 by outputting a significant signal during the period form '1' to '2n1' during which the addresses 10 are in the 1st invalid picture element area. The 2nd comparator 13 opens the 2nd gate 14 by outputting a presence/absence signal during the period from '2n1+1' to '2(n1+n2) during which the addresses 10 are in a valid picture element area. The element driving signal in the valid picture element area has a waveform of one picture element period. Therefore, the address of the memory repeats a value which makes the period from 2n1+1 to 2(n1+1) one period. Then the 3rd comparator 18 opens the 3rd gate 19 by outputting a significant signal during the period from '2(n1+n2)+1' to '2(n1+n2+n3)' during which the addresses 10 are in the 2nd invalid picture element area.

Filed: 1998-08-27
Abstract: PROBLEM TO BE SOLVED: To reduce the factor of failure by connecting one of pair of electrodes arranged in a hot water tank with a voltage generating source and the other electrode with a current detecting circuit and controlling conduction of a water heater thereby simplifying the operation control arrangement of an apparatus. SOLUTION: An upper electrode 11 is arranged in proximity to a water temperature sensor 3 and closely to the full water level and a lower electrode 12 is arranged in proximity to a heater 2 and closely the bottom face in a hot water tank 1. The upper electrode 11 is connected with a voltage supply 13 and the lower electrode 12 is connected with an operation control section 20 through a current detecting circuit 14. When the water in the hot water tank 1 is at full level, the upper electrode 11 conducts with the lower electrode 12 and the current detecting circuit 14 detects a high current level. When it is at a reduced water level, the electrodes do not conduct and a low current level is detected.  These current levels are inputted to the operation control section 20 and idle burning is prevented by interrupting conduction of the heater 2 when the water level is lower than the full water level.

Title: Output protecting circuit
Inventor: TSUCHIYA HIROSHI
IPC: H01L27/06
Filed: 1990-09-13
Abstract: PURPOSE:To increase a surge breakdown voltage of an output protecting circuit by providing current path of different systems by using a drain region of an MOSFET provided to a semiconductor substrate surface. CONSTITUTION:When surge is applied between an output terminal and a Vss terminal, and an output terminal is positive, breakdown occurs in a lateral type PNP transistors Tr 211, 212 and a surge current flows from the output terminal to the Vss terminal. In case of surge of sharp rise, a charge current flows to a parasitic capacity 234 through pull-up diodes 221, 222 and a lateral type NPN transistors Tr 203, 204 turn ON. Therefore, a surge current flows from an output terminal to a Vss terminal through Tr 203, 204, thereby increasing a surge breakdown voltage. That is, a surge breakdown voltage can be increased by providing a P-type high concentration impurity region in an area near a drain region of a P-type MOSFET and by increasing path of a surge current by formation of Tr 203, 204.

Title: Method of transmitting and receiving periodic pulse row
Inventor: DEIETAA DOUREFUAARU
IPC: G01S7/524
Filed: 1985-10-31
Abstract: A method for measuring the running time of a signal transmitted by a transmitter and received by a receiver is devised, where the signal is transmitted and received by the same transducer. For transmitting the transmitter is driven by an electrical pulse train, and in receiving the received signal is converted back into an electrical signal. In receiving triggering is done on the trailing edge of the envelope of the received signal. At the transmitting side the transducer after its incitement is driven by a pulse train being in phase opposition to the original inciting signal and having a larger amplitude than the original inciting signal which results in a higher steepness of the envelope. At the receiving side the maximum amplitude is measured, and the triggering point of time is determined when the actually measured value of the envelope falls below a certain percentage value of the maximum value.
