Title: Video display device
Inventor: SHINJO TOSHIYUKI
IPC: H04N3/20
Filed: 1998-10-13
Abstract: PROBLEM TO BE SOLVED: To obtain the video display device that can activate a spot killer circuit without being affected by a load change in a ternary winding of a flyback transformer. SOLUTION: A spot killer circuit 30 detects a trailing of a DC voltage V3 that is an output of a regulator circuit 3, and decreases a cathode voltage of a picture tube 12 so as to allow the cathode voltage to reach a cut-off voltage or below when the result of detection indicates a fall of the DC voltage. When a power switch of a television receiver is switched from on to off, a 1st DC power voltage Vl outputted from a main power supply 1 descends and the output of the regulator circuit 3 also decreases, and a transistor(TR) 31 of the spot killer circuit 30 is conductive. Thus, the spot killer circuit 30 decreases the cathode voltage of the picture tube 12 to the cut-off voltage or below and supplies a cathode current so as to prevent a fluorescent screen of the television receiver from being baked due to beam spots.

Title: Heat pump type air conditioner
Inventor: FUJIWARA KATSUHIKO
IPC: F24F11/02
Filed: 1987-11-19
Abstract: PURPOSE: To perform efficient capacity control of cooling and heating operation by detecting the load accurately based on the operating frequency of a compressor, separating the low boiling point component from a nonazeotrope refrigerant depending on the required load and varying the mixing ratio of refrigerant. CONSTITUTION: At the time of heating operation, for example, frequency of a compressor is detected by a frequency sensor 27 and compared with a set frequency stored in a microcomputer 26. If it is lower than the set frequency, a solenoid on/off valve 18 is closed and refrigerant flows as shown by a dot line arrow. A part of refrigerant delivered from an indoor heat exchanger 15 while being released from supercooling enters into a pressure reducer 19 and expands adiabatically up to an intermediate pressure to produce gas components which enter into a rectifying column 16 thence into a cooler 21 before being introduced to a refrigerant storage unit 20 being cooled by suction gas.  Since the refrigerant in the storage unit 20 is thereby rich in low boiling point components while the refrigerant in the main circuit is rich in high boiling point components, capacity and power consumption can be reduced. When the set frequency is exceeded, the valve 18 is opened and refrigerants of high and low melting point components are mixed in the main circuit thus providing a high capacity.

Abstract: PROBLEM TO BE SOLVED: To precisely replace a rotating roller and prevent the measurement failure of carrying speed of a document sheet by measuring the carrying speed of a sheet to be carried by the rotation of a roller member, and displaying the replacement of the roller member when the life of the roller member is judged. SOLUTION: A carrying speed measuring sensor 25 is provided on the upstream side of the carrying direction (arrowed direction B) of a document sheet S and substantially in the vertical center to the carrying direction in order to prevent the oblique traveling of the document sheet by the load of a rotating roller 251 in the carrying of the document sheet S. When the feeding number of the document sheet S is increased, and the life of the rotating roller 251 comes near, a slippage is generated between the rotating roller 251 and the document sheet S by the reduction in frictional coefficient of the rubber surface of the rotating roller 251, and the waveform of an encoder output is not constant. When it can be judged whether such a phenomenon is different from a sudden one, the life of the rotating roller 251 can be judged to replace the rotating roller 251.

Title: Manufacture of printed wiring board
Inventor: YOSHIDA RISABURO
IPC: C23C22/63
Filed: 1994-11-28
Abstract: PURPOSE: To provide a method of manufacturing a printed wiring board which can form a fine wiring pattern of high precision and reduce the manufacturing cost. CONSTITUTION: A photosensitive resist layer is formed on a copper layer arranged on an insulating board. The resist layer is patterned and the copper layer exposed from the resist layer is etched. Thus a copper wiring layer is formed. In the above manufacturing method of a printed wiring board, a pretreatment for the copper layer surface is performed which includes blackening treatment using alkaline oxidation treatment solution and fine surface treatment using phosphoric acid or organic acid treatment solution. After drying treatment is performed under the condition that oxygen exists, the phtosensitive resist layer is formed on the copper layer. As the result of the pretreatment, fine and uniform unevenness is formed on the copper layer surface, and the adhesion to the resist layer is improved, so that permeation of etching solution into the gap can be prevented.  Further the copper surface is oxidized by the drying treatment and the reflectivity is decreased, so that disturbance of the form of the exposure region at the time of pattern exposure can be restrained.

Abstract: PURPOSE:To considerably improve the throughput of communication of a main network by constituting the network with a transmission circuit having a star coupler or a bridge circuit transmitting only communication between plural subnetworks and a transmission circuit having a gateway circuit transmitting only external communication. CONSTITUTION:When a node 5A-1 sends a signal to a node 5A-2 in a same subnetwork 3A, the signal sent from the node 5A-1 is distributed by a star coupler 6A and sent to a node 5A-2 though a star coupler 8A-2 connected directly to the node 5A-2. Even when the signal is received from the node 5A-2, the similar path is taken. When the node 5A-1 sends a signal to other subnetwork 3B. the signal distributed by the star coupler 6A is distributed to other subnetwork 3B by the star coupler 4. In this case, the gateway 2A does not form a communication path to an object subnetwork 3B via a network 1.
