Abstract: PROBLEM TO BE SOLVED: To permit the inexpensive deriving of signals from an A.C. power line by providing a detecting wire in the vicinity of a wire for the A.C. power line in a nonconductive state and deriving signals indicating A.C. line voltage by capacitive coupling. SOLUTION: Electronic equipment 100, which may be an oscilloscope, receives electric power from an A.C. line via a pair of wires 105a and 105b. The wires 105a and 105b are coupled to an internal power source 120. The internal power source 120 supplies operation power for the circuit of the electronic equipment 100. Each detecting line (in other words, a detecting wire) formed of the wires 110a and 110b is nonconductively fixed and is capacitively coupled to each of the corresponding A.C. power line and the wires 105a and 105b. In addition, a processing channel is provided with an amplifier 130, a low-pass filter 140, another amplifier 150, and a control microprocessor(μP) 160.

Title: Electrostatic recording device
Inventor: MIYAZAKI KATSUYUKI
IPC: G03G15/00
Filed: 1984-07-27
Abstract: PURPOSE:To start copying operation automatically and to improve operability by providing a means which detects a platen cover being opened and closed and a means which detects whether there is an original on platen glass or not, and detecting whether there is an original on platen glass or not, and detecting the state in which the platen cover is closed and an original set through both detecting means. CONSTITUTION:When the platen cover 3 is closed, a projection 3a penetrates a hole 22a to operate a microswitch 23, detecting the closure of the cover 3. A color sensor 24 is equipped with detection parts 24a-24d which have sensitivity to only yellow light and correspond to originals B5, A4, B4, and A3 respectively. When a scan is made by a light source 1 for exposure with the cover 3 closed, light is transmitted through the platen glass 1 and reflected by a yellow print part 3b of the cover 3 to enter the sensor 24 as yellow light, thereby detecting the size of the original set on the glass 1 and whether the original is set or not. A signal from the microswitch 23 and a signal from the sensor 24 are received and a CPU25 makes an advance to a copying routine, so that copying operation is started automatically.

Title: Mobile station power source control method for mobile radio system
Inventor: YUMIBA MASAHIRO
IPC: H04B7/26
Filed: 1993-06-28
Abstract: PURPOSE:To reduce the power consumption by turning on the power source of a mobile station at the first super frame and turning off the power source when a simultaneous call signal is completed in the time slot specified to a simultaneous call channel. CONSTITUTION:A base station 1 starts in following the information and transmits in succession till the end of a signal when the information with the reception required other than the simultaneous calling channel PCH of report channels, etc., comes from the head slot of the super frame when a simultaneous calling is performed. On the other hand, a mobile station 2 turns on a reception part power supply part 7 at the first super frame and starts receiving a PCH signal at the same time as the head of the time slot designated by the PCH. The timing of turning on and off the reception power supply part 7 is managed by a control part 4 at all times so that the power supply of a control part must be kept turning on. By using the CMOS logic circuit, the power consumption can be saved. When a mobile station 2 detects the end of the PCH, the mobile station 2 turns off the power supply of the reception part at the same time as the PCH signal is ended.

Title: Combustion controller
Inventor: OOTANI HIROSHI
IPC: F23N1/02
Filed: 1983-08-30
Abstract: PURPOSE:To prevent the occurrence of a trouble, such as deterioration in efficiency and an increase in production of NOX which are yielded due to incomplete combustion and air excess combustion, by a method wherein, even if the temperature of the air for combustion is varied, an optimum air-fuel ratio is automatically kept. CONSTITUTION:At the initial set temperature of the air for combustion, a ratio of the opening of a fuel flow rate regulating valve 6 to a fuel flow rate is set as shown by a curve C. In which case, when the temperature of the air for combustion is increased, the temperature is detected by an air temperature detector 11 and is compared with an intitial set temperature by a temperature regulator 12, and an output signal, equivalent to a difference therebetween, is sent to a driving device 13. Thus, the driving device 13 controls the fuel flow rate regulating valve 6 through a link 14 in a direction in which a ratio of a fuel flow to the opening of a valve is decreased, or in the direction of a curve D. This permits prevention of a trouble, such as deterioration in efficiency and an increase in production of NOX which are caused due to incomplete combustion and air excess combustion.

Title: Method of cooling combustion device for gas turbine
Inventor: MINAGAWA YOSHIMITSU
IPC: F23R3/08
Filed: 1978-12-15
Abstract: PURPOSE: To improve the efficiency of film cooling a liner of a combustion for a gas turbine by tapering combustion gas-contacting portions of slit or louver sections of liner-forming cylinders, whereby the mixing of cold air with a combustion gas can be prevented.  
     CONSTITUTION: A combustion gas 16 generated in a combustion device for a gas turbine is supplied to a gas turbine through a liner and a transition case. In the liner, which consists of cylinders 11W13 of different diameters axially connected to form slits 14a, 14b therebetween, cold air 14 sucked through these slits flows in the form of a film to cool the liner. In this cooling structure, the inner diameters of the front end portions of the inner cylinders 11, 12 defining slits 14a, 14b are gradually decreased toward the front ends thereof to form tapered end portions. This serves to prevent the sucked cold air and the combustion gas 16 from being mixed with each other. Accordingly, the liner can be cooled effectively.

IPC: C08L79/08
Filed: 1985-07-17
Abstract: PURPOSE:To obtain a high reproducing output by forming the lower layer obtained by adding a specified amt. of other elements to cobalt and chromium on a base, forming the upper layer obtained by adding the smaller amt. of the same elements to cobalt and chromium on the lower layer to form the titled vertical magnetic recording medium, regulating the coercive force of the lower layer in the in-plane direction to 10-220Oe and controlling the thickness to <=0.15mum. CONSTITUTION:The lower layer obtained by adding a specified amt. of other elements to cobalt and chromium is formed on a base and the upper layer obtained by adding the smaller amt. of the same elements to cobalt and chromium is formed on the lower layer to obtain a vertical magnetic recording medium. The coercive force of the lower layer in the in-plane direction is regulated to 10-220Oe and the thickness is controlled to <=0.15mum. Consequently, since the magnetic flux emitted from a magnetic head is passed through the upper layer and absorbed rapidly and sharply by the magnetic pole of the magnetic head, strong residual magnetization is generated in the upper layer and hence a high reproducing output can be realized.

Title: Electric blower
Inventor: SHIMADA SADAHIRO
IPC: F04D29/44
Filed: 1988-06-27
Abstract: PURPOSE:To make improvements in air blasting efficiency by forming a return passage in the back side of an air guide, installing a tilting rib in the midway, and forming each inlet port of a motor in a lower part of the return passage and a peripheral upper side face of the motor respectively. CONSTITUTION:An air flow out of the circumference of a fan 29 flows in a horizontal direction, but since a wall 41 in the lower part of an expansion passage 40 is tilted downward in proportion as heading for the circumference, it comes to a flow going to the lower part, and at the backside of an air guide 22, it comes to a flow of about 120 deg. to horizontally by an upper wall 43 of an interconnecting passage and a tilting rib 45 of the air guide 22. Since it comes to a lower current at the expansion passage 40 in substance, a change in the flow direction at the interconnecting passage comes to about 100 deg. or so, so that it comes to a very smooth, efficient flow. Thus, the tilting rib 45 heading for drainage is installed in a return passage 44 of the air guide 22, so that any change in the flow direction on the circumference of the air guide 22 is little as compared with the conventional one, thus such an electric blower that is high in air blasting efficiency is securable.
