Title: Dielectric filter
Inventor: KAGA KIMIE
IPC: H05K3/34
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To prevent the deterioration of a filter characteristic by means of heat at the time of reflow soldering by permitting the film thickness of a nickel layer in an inductor electrode formed on a print substrate to be equal to lower than a specified value. SOLUTION: The inductor electrode 2c is formed on the print substrate 2 and is provided with a nickel layer and metal on a copper layer and the film thickness of the nickel layer is less than 2μm (zero μm excluded). The lower limit of the film thickness of the nickel layer can be any value if a gold plating layer is formed on the copper layer. But gold plating is not executed in zero μm so that it is not included in a range. Though the nickel layer and metal are formed by plating, formation is not limited to it and a method such as a vapor deposition, etc., can be used if equivalent film thickness is formed. Thus, the reduction of an electric conductivity caused by the composition change of the electrode on the print substrate 2 owing to heat at the time of reflow soldering is restricted.

Title: Compressor circuit
Inventor: OOHIRA HIDEAKI
IPC: F04B49/06
Filed: 1982-06-08
Abstract: PURPOSE:To reduce power consumption by opening a solenoid valve and forming a bypass circuit so as to balance between high and low pressures rapidly and to return to a restarting status of a compressor when the compressor is stopped by an action of an overload relay. CONSTITUTION:When a solenoid valve 1 is de-energized, the plunger 9 of the solenoid valve 1 is lowered by means of its own weight and the elasticity of a return spring 16, and a rod 10 depresses a valve body 7 so as to open a pilot hole e, then a flow passage of a fluid is formed from an inlet A through a gap alpha, guide holes a, b, pilot hole e, a passage d, and a bypass 13 to an outlet pipe. Since the gap alpha between a main valve 3 and the inner wall of a vacant cavity c is smaller than the gap beta of the pilot hole e, the fluid flowing out from above the main valve 3 becomes greater than that flowing in, thereby the main valve 3 is floated upward until it gets into contact with a stopper 4 and is stopped, causing a valve seat 2 to be opened. Therefore, a bypass route 37 is opened by the solenoid valve 1, coupling the discharge side high pressure 35 with the suction side low pressure 36, thus the restarting status of the compressor can be obtained rapidly.

SOLUTION: A die pad 4 is constituted by lowering the pad in the direction of the rear surface of the surface, where an inner lead 6 and a bonding wire 3 are connected, so that the height of the upper surface of the inner lead 6 at the surface, where the inner lead 6 and the bonding wire 3 are connected, agrees with the height of the upper surface of the bonding wire ball 3. Thus, the bonding wire 3 and the end part on the side of a semiconductor chip 1 on the side of the inner lead 6 do not become contact. That is to say, the trouble, wherein the electrode of the semiconductor chip 1, to which the bonding wire 3 is connected, and the semiconductor chip are electrically short-circuited and the inconvenience that the function required for the semiconductor chip 1 is not normally operated, does not occur.

Title: Multi color electrophotographic device
Inventor: KOBAYASHI TATSUYA
IPC: G03G15/01
Filed: 1989-04-19
Abstract: PURPOSE:To obtain a bright image by setting each value to fulfill a specified formula, making surface opposing distance D of a second developing means D 50 to 500mum, electrifying quantity Q per unit mass quantity of a developer image, bias voltage Vmin, and toner part electrifying potential VDT. CONSTITUTION:The problem of toner of a first toner layer mixing into a second developing device, and as a result generating mixture of colors, is largely related to the potential difference between the developing bias voltage Vmin and toner part electrical potential VDT of a first image and the electrifying quantity Q. The larger the potential difference ¦VDT-Vmin¦, the toner of the first toner image on the photosensitive drum is easily mixed into the second developing device. Because each toner of the first toner image is adhered to the photosensitive drum from influence of electric charge of the toner itself, the influence becomes greater as the electrifying quantity Q of each toner of the first toner image becomes higher, becoming difficult to be stripped from the photosensitive drum, and becoming difficult to mix into the second developing device. Therefore, by fulfilling the formula I, generation of color mixture can be prevented.

Filed: 1980-07-18
Abstract: PURPOSE:To simplify a means for pressurizing an ink, unnecessitate pipes for an ink circulating system and obtain a high-quality image at low cost by utilizing the pressure of a compressed gas, in a charging control type ink jet recorder. CONSTITUTION:When the ambient temperature is constant, a liquefied gas 24 is evaporated to a gas 24' as far as it attains a certain gas pressure and reaches an equilibrium state. Therefore, a constant pressure is attained in the interiors of a liquiefied gas sealing-in body 18, the first connecting part 21, a pipe 25, the first valve 19, a pipe 26, the second connecting part 22 and an ink cartridge 17. When the second valve 20 is opened and the ink 29 is jetted from an ink jetting head 1, although the amount of the ink contained in the cartridge 17 is reduced, the gas pressure is always maintained at a fixed pressure by the evaporation of the liquefied gas, and therefore, variations in the mass and velocity of the jetted ink droplets are eliminated. Accordingly, the quality of the printed image becomes excellent and pipes for the ink circulating system are unnecessitated.

Title: Forced convection type heater
Inventor: YAMAZAKI TOSHIO
IPC: F23N5/26
Filed: 1992-04-17
Abstract: PURPOSE:To improve the safety of a forced convection type heater by a method wherein an operating time is set to a certain limited time even if an operation switch is manually operated to instruct a starting of operation. CONSTITUTION:As operation is started through an operation switch 2, a certain specified time is started to be counted by a timer means 18. An alarm means 24 generates an alarm before the specified time is finished for its counting. At this time, as clearing means 19 and 20 are operated, a time counting of the timer means 18 is cleared, so that an operation stopping instruction signal is not generated and operation of a heater is continued. However, if the clearing means 19 and 20 are not operated, the operation stopping instruction signal is generated when the timer means 18 counts the specified time and the operation is stopped and then indoor air is prevented from being contaminated further. With such an arrangement, the safety caused when the forced convection type heater having no air feeding or discharging cylinder is improved.
