Title: Method of operating otto-cycle engine
Inventor: NOGUCHI MASAAKI
IPC: F02B1/04
Filed: 1977-10-03
Abstract: PURPOSE:To reduce fuel consumption of an Otto-cycle engine and minimize the amount of NOx contained in the exhaust gas, by chemically activating a portion of mixture with starting of induction discharge near the bottom dead point before entering into compression cycle, thereby diluting the mixture and improving ignitability of fuel, notwithstanding that amount of exhaust gas recirculated is increased. CONSTITUTION:In addition to a first ignition means 20 which applies a high voltage to ignition plug 18 for ignition of mixture, the ignition plug 18 is connected with a second ignition means 30 which produces induction discharge at the ignition plug 18. The second ignition means 30 consists of a synchronous pulse generator 31 for generating pulses synchronus with the revolution of engine 10, a driving pulse generator 32 for generating driving pulses in response to the synchronous pulses, transistor 33 and converter 34. With generation of pulses from pulse generator 32 near the bottom dead center during suction cycle, discharge of ignition plug 18 is started and maintained, and redical forming reaction is caused in the mixture so that it is highly activated chamically. Thus, ignitability of mixture is extremely enhanced.

Title: Ink-jet recording head
Inventor: TOUNO NAN
IPC: B41J2/045
Filed: 1996-05-14
Abstract: PROBLEM TO BE SOLVED: To enable representation of a wide gradation by providing a nozzle in a head part or providing an ink-repellent part near to the nozzle in a different mode and discharging a drop of ink having large diameter from the discharge part of the drop of ink having large diameter in comparison with the discharge part of the drop of ink having small diameter. SOLUTION: Since an ink-repellent layer is not provided in a nozzle 28 in a head part 12 having large diameter, the meniscus face of ink 26 exists on the discharge side of the nozzle and a drop of ink having large diameter is discharged from the nozzle 28. Since the inkrepellent layer is formed in the inner face of the nozzle 28 and in the prescribed region of the inner face of a channel plate 16 surrounding it in a head part 14 having small diameter, the meniscus face of ink 24 exists near to the inside end part of the nozzle 24. A drop of ink having small diameter is discharged from the nozzle 28. Gradation properties are widely changed by suitably selecting the head part 12 having large diameter and the head part 14 having small diameter in accordance with the conditions of an outputted image to be formed and also changing voltage impressed between a common electrode 38 and an individual electrode 40.

Title: Controller for shutter
Inventor: SAITOU TSUTOMU
IPC: G03B27/72
Filed: 1985-06-03
Abstract: PURPOSE:To enable control, in which the capacitance of a DC motor is employed up to the maximum, by previously memorizing the driving voltage waveform of the DC motor required for opening and closing a shutter in the shortest time to a ROM, reading the contents of the driving voltage waveform in succession and DC-converting them at every open-close of the shutter and transmitting the contents over the DC motor. CONSTITUTION:The time for driving a shutter disk to open from close and to close from open is represented by ta and the number of the positions of memory in a ROM 5 by (n). Motor voltage V(ti) at each time ti (i=1,2...n) obtained by dividing t1 into (n) is binary-coded, and recorded to several position of memory of the ROM. RaImax enters an address such as a head address in the ROM and -RaImax an address such as the last address. Accordingly, when n pulses are applied to a binary counter 6 as pulse row signals 7 for the time ta, the contents of the ROM are read in succession at respective time ti, DA- converted, and transmitted over a DC motor, thus conducting the expected driving of a shutter.

Title: Surface acoustic wave device
Inventor: NAGATSUKA TSUTOMU
IPC: H03H9/145
Filed: 1992-04-14
Abstract: PURPOSE:To obtain the surface acoustic wave device having a high inter conversion efficiency between an electric signal and a surface acoustic wave by forming at least part of a border line formed by tying ends of a region in which electrode fingers of interdigital electrodes are in crossing to be a sawtooth shape along a propagation direction of a surface acoustic wave. CONSTITUTION:The shape of lines formed by tying ends of a region where electrode fingers 4 forming interdigital electrodes 3 are in crossing is formed to be a sawtooth shape in the propagation direction of a surface acoustic wave as shown in dotted lines. Thus, the amplitude of the surface acoustic wave stimulated by the electrode finger 4 has a distribution larger in the middle and gradually smaller toward both ends along the cross width direction, that is, the X axis direction by taking several adjacent electrode fingers into one set. Thus, a surface acoustic wave is made incident on a waveguide path 2 efficiently and the inter-conversion efficiency between an electric signal and a surface acoustic wave.

Water electrolysis is carried out by further adding water 12 to a cathodic chamber 4' equipped with a cathode 4 and by adjusting the concentration of NaOH formed at a value of 1W60g/l. Cl formed in the anodic chamber 3 is partly used for sterilization as it is and is partly led to a chamber 6 together with an NaOH liquid formed to form NaOCl, which is used for water sterilization. In this process, the ion exchange membrane 2 can be used for a long time without being clogged with hardly soluble Ca salts.
