Title: Picture signal correcting device
Inventor: HOSOI KIYOO
IPC: H04N7/18
Filed: 1980-11-12
Abstract: PURPOSE:To compensate the level fluctuation of a picture signal caused by various factors by detecting the envelope of the picture signal and dividing a picture input signal with the related output signal. CONSTITUTION:A corrected picture signal OUT is obtained from the output terminal of a dividing device 2 by taking out the envelope part of a picture signal IN by means of an envelope detector 1, and feeding this output signal into the dividing device 2 in order to divide the picture signal IN. On the other hand, the envelope detector 1 is formed with the low pass filter of an integral device AP, which connects the resistance Ra, Rb to the input side, the capacitor Ca between the device AP1 and an earth and a capacitor Cb between input and output. Therefore, since the picture signal IN is divided every moment by the envelope signal X and is corrected so as to keep the evelope at a constant value, it is possible to compensate the level fluctuation caused by the various factors of shading, etc. correctly in order to improve the precisin of picture processing.

Title: Air conditioner
Inventor: TANI SHUICHI
IPC: F25B13/00
Filed: 1991-06-28
Abstract: PURPOSE:To prevent damage of a compressor by providing control means for increasing a valve opening of a special flow controller by a predetermined amount if a discharge temperature detected by discharge temperature detecting means provided between the compressor and a four-way switching valve is higher than a preset predetermined temperature. CONSTITUTION:If a discharge temperature detected by discharge temperature detecting means 42 exceeds a preset predetermined temperature during an operation of a compressor 1, a valve opening of a third flow controller 15 of third and fourth flow controllers 15 and 17, is preferentially increased. In this manner, a pressure loss is reduced to allow refrigerant to easily flow. Thus, quantity of refrigerant to be returned to a heat source A is increased, a specific volume of refrigerant to be sucked to the compressor 1 is reduced, and rise of the discharge temperature can be suppressed. That is, a decrease in lubricity of refrigerator oil due to excessive rise of the discharge temperature and hence damage of the compressor 1 are prevented.

Title: Serial printer
Inventor: TANIHATA HIROSHI
IPC: B41J19/18
Filed: 1988-06-27
Abstract: PURPOSE:To realize bidirectional printing without any positional deviations by using the difference between the number of pulses, n, in a first direction for a printing head and the number of pulses, n', in a second direction reverse to the first direction, as a correction value for the positional slippage. CONSTITUTION:A home position 10 on a platen 1 is detected by a position detector 8, and an end surface 2a of a recording paper 2 is detected, upon which a counter is started. When a pulse count reaches n, a switching signal is sent to a head-feeding part 4, whereby the feeding direction of a printing head 3 is reversed from a forward direction to a backward direction, and simultaneously, the counter is newly started counting pulses. When the end surface 2a is detected, the pulse count n' at that moment is stored. In the presence of ordinary mechanical chattering, naturally n'>n. Therefore, when n'-n=n'' is stored, then the feeding direction of the head 3 is again set to be the forward direction, and thereafter printing of data is conducted with a delay of the pulse number n'', a positional deviation in the moving direction due to slippage according to the mechanical chattering is corrected, and normal printing is conducted.

IPC: G01L5/22
Filed: 1999-06-07
Abstract: PROBLEM TO BE SOLVED: To detect a torque accurately by providing an insulating means between the sensor shaft of a torque detecting means and the input shaft of a steering and breaking a horn current flowing through the input shaft not to flow into the torque detecting means by the insulating means thereby preventing fluctuation of output from a torque sensor. SOLUTION: An input shaft 3 having one end coupled with a steering wheel 2 is coupled with the sensor shaft 72 of a torque detecting means 7 through an input shaft coupling means (inner collar) 4, i.e., a metallic tube having noncircular outer circumferential surface. Outer circumferential surface of the inner collar 4 is covered with a rubber insulating means 5 and since the inner collar 4 is press fitted to the outer collar part 3b of the input shaft 3 through the insulating means 5, the input shaft 3 and the sensor shaft 72 are coupled under insulated state. A horn current also flows through the input shaft 3 when a horn switch 2a is depressed, but it is broken by the insulating means 5 not to flow into the sensor shaft 72. Consequently, characteristics of the torque detecting means 7 are not varied and sensor parts can be protected against deterioration.

Title: Formation of high purity silver film
Inventor: UCHIDA HIROTO
IPC: C23C16/48
Filed: 1995-06-26
Abstract: PURPOSE: To easily and efficiently form a high purity Ag film at a low reaction temp. by an Ag-MOCVD method by which vapor of an org. Ag compd. is degraded and Ag is deposited on a substrate. CONSTITUTION: Vapor of an org. Ag compd. is degraded by irradiation with light of >=240nm wavelength and Ag is deposited on a substrate. By this photodegradation-MOCVD method, high-speed film formation at <=200 deg.C is enabled. Unlike the conventional thermal decomposition-MOCVD method at >=250 deg.C high temp. and high humidity this method prevents the deterioration of the purity of a film due to the decomposition of a ligand and the lowering of the density of a film due to the insular aggregation of Ag on a substrate and the objective dense high purity Ag film is efficiently formed.

Title: Television picture receiver
Inventor: YAMADA TADASHI
IPC: H04N5/63
Filed: 1978-12-26
Abstract: PURPOSE:To eliminate one unit of the Zener diode as well as to increase the reliability by securing more than two kinds of performance for one unit of the Zener diode. CONSTITUTION:The power switch is turned on, and the fixed potential is applied to +B2 through resistor 12 along with the current flowed to Zener diode 1. On the other hand, E-B of transistor Tr8 is cut off since it functions the backward diode at the side of the low-voltage circuit, and the constant voltage is generated across diode 1 to actuate the horizontal oscillation circuit. As a result, the pulse is generated to output winding 10b of FBT and then rectified by diode 3 and capacitor 4. While the base of Tr9 features the constant voltage via the voltage at both ends of diode 1 as well as the forward voltage of B-E of Tr8, and the constant voltage power source lower than the base potential by the amount equivalent to the B-E forward voltage is obtained at the emitter of Tr9 through collector resistance 17 to be supplied to the low-voltage circuit. Furthermore, diode 1 is utilized to amplify the error. In case the X-ray protective circuit exists, the increasing voltage of winding 10b is detected to operate the protective circuit, thus preventing the secondary breakdown for resistance 17, FBT10, diode 3 others.
