Title: Driver device for solenoid valve
Inventor: KAWAMURA HIDEO
IPC: F01L9/04
Filed: 1989-07-13
Abstract: PURPOSE:To increase the driving force for opening and closing a suction/exhaust valve without causing the power supply being dimension in large size, by supplying electric charges on a capacitor to an electric magnet, and thereby energizing it. CONSTITUTION:When the crank angle sensed by a rotation sensor 7 attains the opening timing for a suction valve 1 set previously, a capacitor 52 in charged condition is shut off from the power supply 5 in conformity to an opening/closing signal given by a control unit 6 and also a closed circuitry is formed with No.2 coil 32 and a normally closed switch 54, so that a large current is fed to this No.2 coil 32 from the capacitor 52, and a downward oriented large-density mag. flux is generated in an upper fixed mag. pole 31. To No.1 coil 23, by contrast, a large current is fed from another capacitor 56 in the direction of generating an upward oriented mag. flux in the magnetism passage 2. Thereby a strong repulsive force acts between the top surface of the magnetism passage 2 and the upper fixed mag. pole 31, and the magnetism passage 2 and suction valve 1 move quickly downward, i.e. in the direction of opening.

Title: Semiconductor exposure device
Inventor: INE HIDEKI
IPC: G03F1/54
Filed: 1996-06-21
Abstract: PROBLEM TO BE SOLVED: To make it possible to obtain sufficiently high resolving power in spite of use of projecting optical system in which coma aberrations exist by setting the height of the chromium patterns of a reticle to be used at integer times of the half number of a central frequency. SOLUTION: The reticle 3 is formed with chromium layers 5 of a prescribed height H in the prescribed positions of a quartz glass substrate 4. The prescribed height H is set at a nearby value satisfying the conditions of H=N.λ/2 with respect to the central frequency λ for the purpose of exposure. N denotes a positive integer. The relation between the difference Idef between the intensity of the scattered light SL1 to 3 scattered on the left side of the chromium layers 5 on a wafer and the intensity of the scattered light SL4 to 6 scattered on the light side and the height H of the chromium layers 5 is such that the amplitude of the intensity difference Idef changes sign functionally of λ in the period in proportion to the coma aberrations.  The height H of the chromium layers 5 at which the intensity difference Idef attains zero satisfies the relation H=N.λ/2 without depending on the coma aberrations.

Abstract: PURPOSE:To obtain a device by which density is accurately detected for each color and whose constitution is miniaturized by providing containers for plural colors of developer in a developing means and providing a light emitting element and a light receiving element corresponding to each color. CONSTITUTION:Toner sucked from a developing tank passes through a pipe 39 and is thinly extended by a cell joint 41a to enter a detection cell 43, and further it flows from the cell joint 41b to a pipe 40. In the part of the detection cell 43, the density is detected by LEDs 37a-37b and photodetectors 38a-38d corresponding to the respective colors for each toner, and the detected result is transmitted to a control circuit through an amplifier circuit and a comparator circuit. The control circuit judges based on the detected result about the density for each color what color is thin. When wavelength having the largest light absorbing degree is selected in order to detect the density for each color, the accurate detected result is obtained. Therefore, for example, the light of about 550nm is emitted and received to detect the density for black developer.

Filed: 1985-08-20
Abstract: PURPOSE:To generate a forecasted residual signal of less amplitude level variance by dividing an audio signal to individual frequency bands and subjecting the audio signal in each band to the proximity forecast encoding processing and the pitch forecast encoding processing. CONSTITUTION:The inputted audio signal is divided to plural (n-number of) frequency bands by a band dividing filter 110, and audio signals X1-Xn of corresponding bands are subjected to proximity and pitch forecast encoding processings by forecast encoding means 1201-120n to generate forecasted residual signals E21-E2n.

Title: Glow plug for starting direct injection type diesel engine
Inventor: YANAGISAWA NAOKI
IPC: F23Q7/00
Filed: 1983-09-30
Abstract: PURPOSE:To make it possible to apply the after-glow without using a controller that controls the electric current to a glow plug by connecting in series two coils as a heat generating coil which have different tempeature-resistance coefficient. CONSTITUTION:When a voltage is applied to a heat generating coil 23 for starting, a rush coil 25 and a brake coil 27 are low in resistance as the temperature of the heat generating coil 23 itself is low, and so, a large amount of electric current flow through the rush coil 25 to quickly raise its temperature so as to lead to an early combustion of engine. Meanwhile, as the temperature of the rush coil 25 becomes higher, the temperature of the brake coil 27 which is connected to it in series becomes higher at the same time. However, since the temperature-resistance coefficient of the brake coil 27 is large, the amount of resistance becomes greater. As the amount of resistance increases, the electric current flowing through the heat generating coil decreases, and the temperature rise at the rush coil section 25 of the glow plug is held below a certain level to maintain the after-glow temperature between 800 deg.C and 1,000 deg.C. Therefore, a better rev-up characteristics is achieved.

According to this, the current is carried also to an area 6 to which the current is hardly carried because it is not nipped between the feeding electrodes and which is hardly heated because no current collection is caused to make this area 6 easy be heated. Accordingly, the cloudiness preventing performance is improved.

Abstract: PROBLEM TO BE SOLVED: To uniformly mix the fuel and air in a premix compression auto- ignition operation by operating a second fuel injection pump of a premix fuel injection nozzle mounted at an upstream of an exhaust reflux valve in a low load operation zone, and operating a first fuel injection pump of a fuel injection nozzle of a cylinder head in a zone more than the intermediate load operation. SOLUTION: A premix fuel injection nozzle 6 connected to a second fuel injection pump 11 is mounted on a exhaust reflux (EGR) circuit 4, and a cylinder fuel injection nozzle 7 connected to a first fuel injection pump 9 is mounted on a cylinder head. In the low load operation, the second fuel injection pump 11 is switched on, and in an intermediate load operation zone, the first fuel injection pump 9 is switched on. That is, the operation of premix compression auto-ignition mode is executed in the low load operation, and the operation of compression ignition mode is executed in a zone above intermediate load.  As the premixed fuel is injected into an EGR tube of high temperature in the low load operation zone of high demand for the uniform mixing, the premixed fuel is immediately volatilized, and introduced into new air (intake) with the EGR gas, and the uniform air-fuel mixture is obtained by the mixing of different gases.
