Title: Speed change control device for automatic transmission
Inventor: NAKAGAWA NORIHISA
IPC: F16H59/36
Filed: 1991-07-23
Abstract: PURPOSE:To prevent busy shifts due to excessive corrections by modifying a correction factor using a predetermined change rate when a change in the correction factor representing the ratio of actual quantity of intake air for an engine to required quantity of intake air is obsevered. CONSTITUTION:A transmission control computer 34 switches and controls speed change stages according to predetermined speed change conditions depending upon the quantity of intake air Qm, the opening of a throttle valve TA, the number of revolutions of an engine NE, velocity V, speed change stages of an automatic speed change gear 68, and the position of a shift lever. To control speed changes properly, a correction factor K representing the ratio of actual quantity of intake air for the engine to required quantity of intake air which is determined using the opening of the throttle valve TA and the number of revolutions of the engine NE is determined. This correction factor K is compared with the correction factor from the previous cycle MK and if K is different from MK, MK is modified using predetermined change rates alpha1, beta1. This constitution prevents busy shifts due to a temporary rapid change in the correction factor K.

Title: Plasma processor
Inventor: TAKASHIMA TORU
IPC: B08B6/00
Filed: 1998-07-22
Abstract: PROBLEM TO BE SOLVED: To prevent arc generation between a substrate and a ground. SOLUTION: A holder 5 is connected to the ground via a varistor 22. A negative bias voltage between the substrate and the ground where an abnormal arc is generated is measured preliminarily to select the rated varistor of which resistance is reduced remarkably by a voltage a little lower than the bias voltage taking a safety factor into account, to cause a current to flow from the substrate to the ground. A voltage between the substrate and the ground is detected by detected resistance all the time. When the voltage reaches to the rating of the varistor 22, the varistor 22 makes a current corresponding to an excess charge accumulated in the substrate flow to the ground.

Title: Control device for brake fluid pressure
Inventor: MIYAKE KATSUYA
IPC: B60T8/26
Filed: 1986-09-04
Abstract: PURPOSE:To obtain a brake effect suitable for four wheel driving, by increasing a crossover fluid pressure in the fluid pressure characteristic of rear wheel brake fluid pressure control valves higher then that in the time of two wheel driving interlocking to the switching from the two wheel driving to four wheel driving so that a rear wheel brake fluid pressure is high increased in the time of the four-wheel driving. CONSTITUTION:A fluid pressure brake is applied through a master cylinder 2, valves 7a, 7b and pipes 4a, 4b by actuating a brake pedal 1 to be depressed. Fluid pressure control valves 8a, 8b, which are provided in a piping part to rear wheels, performs a crossover pressure reducing control. Each fluid pressure control valve 8a, 8b, which enables a crossover fluid pressure to be freely changed by a motor 10 operating on the basis of the switching of a two wheel/four wheel driving selector switch 9, increases the crossover fluid pressure in the fluid pressure characteristic in the time of four wheel driving. An increase of the crossover fluid pressure in the above results in the application of a brake fluid pressure, in the time of the four wheel driving, higher than that in the time of two wheel driving, and an optimum brake effect for the four wheel driving can be obtained by generating force, applied to a transmission gear, relatively smaller in the time of applying the brake.

Filed: 1988-08-20
Abstract: PURPOSE:To move a focus lens group by an angle of rotation suitable to high- speed automatic focusing by reducing play on a manual operation ring by utilizing a differential mechanism consisting of a planetary gear mechanism. CONSTITUTION:In the automatic focusing operation, the driving force of a motor 21 is transmitted to a planetary gear 25 through a driving force transmission cylinder 24, and when this gear revolves, the gear of an operation member 27 is fixed, so the planetary gear is put in rotating motion to rotate a lens driving cylinder 20 which supports the gear 25 pivotally, and lenses LA and LB are moved back to perform the automatic focusing operation. In manual focusing mode, the driving force transmission cylinder 24 is turned off by a switching member 31 and the rotating force of a manual operation member 27 is transmitted to the planetary gear 25 through the gear of the operation member to rotate the planetary gear 25 while revolving it; then the lens cylinder 20 which supports the gear pivotally is rotated to move the lenses LA and LB back, thereby performing the manual focusing operation. Consequently, the play is suppressed and the fast automatic focusing is performed.

Title: Method for winding iron core using amorphous alloy
Inventor: HANAOKA KATSUMI
IPC: H01F41/02
Filed: 1986-09-02
Abstract: PURPOSE:To eliminate troubles (such as an increase in excitation loss, generation of creases on the iron core inside part, irregularitiy end planes in the axial direction of the iron core) due to winding fastening and beside to prevent occurrence of troubles (such as a decrease in space factor and readiness to deformation) due to very small winding tension, by specifying initial winding tension for initial winding of the iron core and decreasing the winding tension almost uniformly as the winding goes and specifying final winding tension. CONSTITUTION:Initial winding tension of an iron core is set rather high and the tension is decreased as winding goes so that final winding tension is made 75% or less of the initial winding tension. When the winding tension (whose unit is expressed in kg/25mm) per 25mm in width of an amorphous alloy is 0-1 kg/25mm, excitation loss does not change, but when it becomes in excess of 1 kg/25mm, the excitation loss increases. Even in case of the winding tension being 1 kg/25mm, no troubles (such as generation of creases in the iron core inside part and irregularity of axis directional end planes of the iron core) occurred. On the other hand, the space factor of the iron core increased as the winding tension increased, but the amount of its increase was very small when the winding tension was in excess of 1 kg/25mm. When a decrease rate of the winding tension is set 0.25 or more, the excitation loss decreases. Therefore, as conditions for winding the iron core, it is suitable that the initial winding tension is about 1 kg/25mm and the final winding tension is 0.75 kg/25mm or less.

Title: Injection molding method and injection molding
Inventor: TANUMA YOICHIRO
IPC: B29C45/00
Filed: 1999-07-22
Abstract: PROBLEM TO BE SOLVED: To provide an injection molding method, in which neither waste of material nor waste in a process develops, and an injection molding. SOLUTION: An insert article 1 in coated with a silicon rubber primer at its peripheral surface at a part to be injected as a processing agent in advance, is installed at a predetermined position between an upper side mold and a lower side mold. Under the state just mentioned above, injection material is injected in the mold. Since the silicone rubber primer forms an elastic primer layer P on the part to be injected of the insert article 1, the primer layer P deforms along the shape of a gap formed between the under surface of the upper side mold and the top surface of the insert article 1 so as to clog the gap, no injection material flows in the gap, resulting in preventing a burr from forming.

Title: Pwm inverter with variable gain adaptive control function
Inventor: KOMATSUZAKI YOSHIHIRO
IPC: H02M7/48
Filed: 1992-07-13
Abstract: PURPOSE:To improve a distortion factor of an output voltage waveform without deteriorating stability at the time of loading a rectifier by instantaneously controlling an output voltage according to a gain adapted for a load mode. CONSTITUTION:The PWM inverter with a variable gain adaptive control function comprises a proportional element 2, a stabilized compensator 3, a comparator 6, an output voltage feedback circuit, etc. It detects a carrier signal included in an output voltage of a PWM inverter 7 through an adaptive compensator 20 having a high-pass filter 21, an absolute value detector 22, a low-pass filter 23 and a gain calculator 24, calculates a gain corresponding to the amplitude, and then feeds back it to the element 2. As a result, since the gain of the output signal from the element 2 becomes variable, a control signal for controlling the inverter 7 by the output signal can be switched to a gain adapted for the load mode. That is, a carrier component is used, thereby improving a distortion factor at the time of loading a rectifier.
