Title: Multi-point ignition device
Inventor: YOSHINAGA TOORU
IPC: F02P13/00
Filed: 1982-04-16
Abstract: PURPOSE:To make the required voltage for a plug reducible, by enlarging capacitance between an intermediate electrode which forms the plural number of spark gaps with a high-tension electrode, and a ground electrode, as larger as four times than the capacitance between each of electrodes. CONSTITUTION:A high-tension electrode 1, an intermediate electrode 2 and a ground electrode 3 are all protrusively installed on a base plate 4 installed interposingly between the head and block of a cylinder, forming spark gaps S1 and S2 respectively. In addition, the intermediate electrode 2 froms a capacitor Cg with both a copper plate 22 connected to a couple of electrode members 2a and 2b and a metallic base plate 4 opposite to the copper plate 22 via an insulator 21 and a seal material 23, and this capacitance Cg is made larger as far as four times than capacitance Ce possessed by spark gaps S1 and S2. When doing like this, the impressed voltage VP2 is divided by these Ce and Cg, and the partial voltage V1 of the gaps S1 glows larger than the partial voltage V2 of the gaps S2 whereby discharge is effectively started in regular sequence. Therefore, it is not necessary to generate high-impressing voltage by means of an ignition coil.

Title: Surface acoustic wave filter
Inventor: ISE EIJI
IPC: H03H9/145
Filed: 1995-02-28
Abstract: PURPOSE: To improve the situation of broken wire or mis-bonding by arranging obliquely positions of opposed wire bonding pads for wire bonding. CONSTITUTION: A half-cut groove 5 is made between a 1st lateral coupling surface acoustic wave element 3 and a 2nd lateral coupling surface acoustic wave element 4 to prevent interference between both the lateral coupling surface acoustic wave elements 3, 4, and the arrangement of wire bonding pads required for wire bonding pad for bridging over the half-cut groove 5 is devised. That is, since the interval between both the lateral coupling surface acoustic wave elements 3, 4 is very small, a minimum of 0.3mm for the wire bonding distance executed usually at present is required, then it is impossible to make wire bonding at a right angle to the half-cut groove 5. In this case, wire bonding pads 6 are arranged not at right angles but with a tilt with respect to the half-cut groove 5. Thus, the distance between the wire bonding pads 6 is selected to be 0.5mm or over.

Title: Electronic musical instrument
Inventor: OKAMOTO SHIMAJI
IPC: G10H1/053
Filed: 1978-05-31
Abstract: PURPOSE: To produce rich musical tones such as those of natural musical instruments with a  simple constitution by setting the frequencies of respective components based on the time change  degree numbers of the basic wave and the respective components of its higher harmonic waves  and the frequency numbers corresponding to the pitches of touched keys.   
     CONSTITUTION: Frequency numbers R read out in correspondence to touched key pitches from a  frequency number memory 2 are inputted to a higher harmonic component generating circuit 8  to become the cumulated value indicating the sample points to be calculated of musical tone waveform amplitude. On the other hand, a memory address control unit 9 counts clock pulses and  supplies the output thereof as an address signal to a higher harmonic coefficient memory 10 and  therefore the higher harmonic amplitude coefficients corresponding to the degrees of each higher  harmonic are subsequently outputted from the memory 10. Hence, the sine wave amplitude value  of each higher harmonic from the circuit 8 is multiplied by the corresponding higher harmonic  amplitude coefficients in a higher harmonic amplitude multiplier 11 to become the musical tone  signals having non-harmonic characteristic, which are produced as rich musical tones such as  those of natural musical instruments from a sound system 13.

Title: Exhaust system in vacuum device
Inventor: AZUMA KOJI
IPC: F04F9/08
Filed: 1988-03-18
Abstract: PURPOSE:To prevent the back-pressure of oil diffusion pumps from rising more than the critical back-pressure instantly at pump converting time by opening either one of two main valves delaying for a specific time, when vacuum chambers are evacuated by converting from a low pressure pump to the oil diffusion pump. CONSTITUTION:When the insides of vacuum chambers 1 and 2 are evacuated roughly by an oil rotary pump 4, and the pressure in the vacuum chamber 2 reaches about 0.1Torr, for example, a control circuit 11 closes the rough evacuation valve 5 to stop the rough evacuation of the vacuum chambers 1 and 2. Then, as well as a cutoff valve 20 is closed, the ON signal is fed to a trigonal electromagnetic valve 17. As a result, first a main valve 10 is opened to connect an oil diffusion pump 7 with a low exhaust speed to the vacuum chamber 2. Then, when a specific time, three seconds, for example, passes after the main valve 10 is opened, a main valve 9 is opened to connect an oil diffusion pump 6 with a high exhaust speed to the vacuum chamber 1. Consequently, the pressure of the back-pressure side of the oil diffusion pumps 6 and 7 are converted dividing into two times within the pressure scope less than the critical back-pressure value.

Abstract: PROBLEM TO BE SOLVED: To alter the condition of ink suction in response to the state of a nozzle or ink passage of a recording head by incorporating a plurality of sucking operations in a series of operations of a suction pump, selectively combining the plurality of the sucking operations, and changing the number and sucking forces of the operations. SOLUTION: A suction pump 42 can execute a plurality of sucking operations in a series of operations. The operations are selectively combined and number and sucking forces of the operations are changed by selectively combining the sucking operations by controlling via a cam member 43. For example, at the time of replacing an ink cartridge, to suck ink without a problem of foaming, a plurality of short sucking time and small forces of sucking operations are conducted. At the time of maintenance, relatively long sucking time and relatively large sucking forces of sucking operations are conducted. At the time of discharge fault, long sucking time and large sucking forces of sucking operations are conducted. Accordingly, the cartridge can gradually suck the ink while urging the air in the passage by the cartridge.
