Title: Shoe to hardly get stuffy
Inventor: ISHIDA EISUKE
IPC: A43B7/08
Filed: 1996-04-18
Abstract: PROBLEM TO BE SOLVED: To sufficiently ventilate air inside a shoe and outdoor air while preventing water infiltration to the inside of the shoe by forming an opening part to the outside on a sole side face or the like and forming an air passage reaching an upper part inside the shoe near a toe at the opening part. SOLUTION: In order to prevent the stuffiness of this shoe used in a work place for handling water such as a kitchen and a plating plant, etc., ventilation is sufficiently efficiently performed even by the slight change of volume of a clearance between a foot inside the shoe and a wall inside the shoe. That is, a flat air passage member 7 is attached to a hole opened on the upper 13 of a toe part inside the shoe by an eyelet 10. The air passage member 7 is composed of a material provided with flexibility such as a synthetic resin such as vinyl or the like and rubber, etc., the upper part is opened, a lower part is closed and the opening part 2 to the outside is formed on the lower part on one side.  Also, the air passage member 7 can be the one installed in an arch shape continued from both sides of a bottom part inside the shoe to the upper part along the upper 13 for which the appropriate number of the opening parts 3 to the inside of the shoe are formed at the upper part. Thus, the need of a check valve or the like is eliminated and manufacture is performed at a low cost.

Filed: 1988-04-20
Abstract: PURPOSE:To attain the gain control of high accuracy without the influence of disturbance, etc., in simple constitution by controlling the gain of an AGC circuit for servo signal based on respective prescribed average amplitude values during the respective periods before and after synchronizing completion with a PLL. CONSTITUTION:A gain control circuit 6 is activated by a phase synchronization deciding circuit 8a before the synchronizing completion due to a PLL circuit 4. Then, the gain of an AGC amplifier 3 is controlled so that the average amplitude value of the servo signal, which does not discriminate the position bit of the servo signal in one frame of the servo signal as the output of the amplifier 3 and a think bit, can be constant. By the gain control not to need a PLL clock, even when a power source is inputted or the PLL circuit or AGC circuit is instable by the disturbance, etc., the stable gain control can be executed without malfunction. On the other hand, after the synchronizing completion, a gain control circuit 7 is made active and the gain control of the high accuracy is executed based on the average amplitude of a position bit signal, which is included in the servo signal. Accordingly, the gain control of the high accuracy can be executed without the influence of the disturbance, etc., in the comparatively simple circuit constitution and satisfactory servo control is executed.

Title: Moving body azimuth detector
Inventor: SAITO SATOSHI
IPC: G01C17/38
Filed: 1997-04-15
Abstract: PROBLEM TO BE SOLVED: To minimize the influence of disturbance and reduce the accumulation of errors by composing the geomagnetic azimuth from a geomagnetic azimuth detecting means with the rotating angle from a rotating angle detecting means in a frequency area to determine the azimuth of a moving body.

The computer 3 combines the change portions in a fixed time of the azimuth and angle by the respective sensor in a frequency area when the azimuth of a moving body is calculated. At this time, the rotating angle and the geomagnetic azimuth are differently weighted depending on frequency, respectively, such that the angle sensor 2 is weighted in high frequency area, and the geomagnetic sensor 1 is weighted in low frequency area, and outputs the resulting combined value as the azimuth of the moving body. Further, the computer 3 has also the function of changing this ratio of weighting.

Title: Steering force controller for power steering gear
Inventor: HONAGA SUSUMU
IPC: B62D5/24
Filed: 1984-05-15
Abstract: PURPOSE:To simplify a construction and control preload depending on the rotational angle of a steering wheel, by feeding a part of the discharge flow of a pump for a power cylinder, to a cylinder unit for applying an axial thrust to a sectorial shaft. CONSTITUTION:When the speed of a vehicle is low and the rotational angle of its steering wheel is large, a maximum current is applied through the solenoid of an electromagnetic relief valve 60 so that the spring load on the valve is made substantially zero. As a result, a fluid from a pump 50 flows to a tank and pressure does not act to a piston 33, so that only initial preload acts to a sectorial shaft 11. Along with the rise in the vehicle speed or the decrease in the rotational angle of the steering wheel, the electricity applied to the solenoid of the valve 60 is reduced so that the spring load on the valve is augmented. As a result, the fluid pressure from the pump 50 is introduced into a cylinder chamber 32. Under the introduced fluid pressure, the piston 33 pushes the sectorial shaft 11 in the axial direction to increase the preload on both a sector gear 12 and rack teeth 21 to augment manual torque.

A predetermined ratio of guide light of the guided light having a wavelength for satisfying primary Bragg's condition is returned to a laser chip 2, and the remaining guide light is transmitted in the direction of an FGC 6. Then, the light which arrives at the FGC 6 is projected toward an optical disk 7, and condensed on the surface of the disk. Thereafter, the reflected light from the disk 7 is introduced to the layer 2, and detected by a photodetector. Thus, the guided light of the wavelength for satisfying the primary Bragg's condition of the light emitted from the laser 1 is reflected at a predetermined ratio by a DBR 5, and returned to the laser 1. This returned light is amplified in the laser 1. This is repeated to stably oscillator only the light of the wavelength for satisfying the primary Bragg's condition in the laser 1.

Title: Method for measuring concentration of working oil emulsion
Inventor: KOBAYASHI ISAO
IPC: G01N29/00
Filed: 1992-04-17
Abstract: PURPOSE:To highly accurately measure the concentration of working oil emulsion by calculating a plurality of calibration curves obtained from the correlation between acoustic velocities and temperatures by a method in which the curves are connected by using a sigmoid function which smoothly finds the weighted mean of values near their thresholds. CONSTITUTION:After acoustic waves-transmitted from a transmitter 22 against rolling oil flowing through a detection pipe 21 are received 23 and amplified 24, the waves are transmitted to a logic section 32 through a transmission line 41 and volume indicator 31 which counts the waves. A resistance thermometer bulb 25 measures the temperature of the oil and transmits the temperature to a temperature converter through a transmission line 42. The converter 33 converts the temperature into a signal and transmits the signal to the section 32. The section 32 finds the concentration of the oil based on a transmitted sound velocity frequency and temperature value and a concentration output converter 34 outputs the concentration value. This arithmetic operation is performed by a method in which a plurality of calibration curves obtained from the correlation between acoustic velocities and temperatures found from already collected rolling oil emulsion samples is connected to each other by using a sigmoid function which smoothly finds the weighted mean of values near their thresholds. Therefore, the concentration of rolling oil emulsion can be accurately measured in a low, intermediate and high concentration ranges.
