Title: Hydraulic controller for vehicular brake
Inventor: MATSUDA SHOHEI
IPC: B60T8/40
Filed: 1984-07-17
Abstract: PURPOSE:To keep off the occurrence of kickback in a brake pedal as well as to prevent negative pressure in an output hydraulic chamber from occurring, by installing a valve, which opens at a time when oil pressure in the output hydraulic chamber gets reduced more than the setting value, in position between an input hydraulic chamber and the output hydraulic chamber. CONSTITUTION:When control pressure in a control chamber 18 abnormally increases, a first piston 15 and a piston rod 25 both move to the right against a spring 23, but in time of non-braking, a second piston 19 is not moved to the right due to the spring 23 lying between the piston 19 and the piston rod 25. When the amount of travel to the right in the piston 15 exceeds the specified value, a driving rod 39 of a valve mechanism 6 comes into contact with a pressing member 41 unitized with the second piston as one body whereby this valve mechanism 6 opens. As a result, an input hydraulic chamber 16 and an output hydraulic chamber 20 are interconnected with each other, so that a drop of negative pressure in the output hydraulic chamber 20 is checked. And, in time of braking, first both these pistons 15 and 19 move to the right together, but after traveling the specified value, the piston 15 alone moves. Therefore, like the above- mentioned, the valve mechanism 6 opens, thus a kickback phenomenon with reduction in the input hydraulic chamber 16 is prevented from occurring.

Filed: 1981-09-18
Abstract: PURPOSE:To facilitate the temperature control to fix a picture well, by providing a means, which hinders the draft of the face of a belt, near the lower face of the belt just under a halogen lamp. CONSTITUTION:A member 6 is arranged near the lower face of a belt just under a halogen lamp 1. The member 6 is adhered to the inside of the upper part of a housing 7 so that a vent hole corresponding to the area just under the halogen lamp 1 out of vent holes 8 for attraction of a recording paper which are formed in the upper part of the housing 7 is shielded. The lamp 1 and a temperature sensor 4 are covered thermally from a fan 3 for attraction, which is provided in the lower part, and the area just under the lamp 1 is always covered by a recording paper 5 practically. Consequently, since the temperature under the lamp 1 is stabilized and the temperature is detected without the influences of the draft of the fan 3, the temperature control is facilitated to fix an image well.

Title: Optimum emission spectrum automatic detecting system
Inventor: NIIFUKU SATORU
IPC: C23F4/00
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To automatically set an optimum wavelength for detecting the end point prior to the execution of a plasma treatment. SOLUTION: A monochromator 2 is capable of separating a light 18 emitted during trial of a preliminary plasma treatment to select desired wavelength. A servo motor 6 drives the monochromator 2 to automatically sweep wavelengths to be selected in a desired range. A photomultiplier 3 converts the emission received by the wavelengths selected by the sweep into electric signals according to the intensity of the emission by the wavelengths. An intensity difference detection circuit 7 processes the electric signals to detect the change quantity of the emission intensity by the wavelengths before and after the end point of the tried plasma treatment.  An optimum w setting circuit 8 determines an optimum wavelength for the end point detection, based on the change quantity detected by the wavelengths and controls the servo motor 6 to lock the wavelength selected by the monochromator 2 to the determined optimum wavelength. At the plasma treatment thereafter, the circuit 5 detects the end point, based on the time change of the emission intensity at the optimum wavelength.

Filed: 1981-09-22
Abstract: PURPOSE:To prolong the service life of a pump used for circulating muddy water or the like, by increasing the wear resistance of the inner surface of a cylinder with which a piston is kept in sliding contact. CONSTITUTION:A cylinder liner 1 made of a high alloy steel is quenched and temperature and high-frequency quenching is applied to the inner surface of the cylinder liner 1, so that the inner surface is imparted with a hardness Hv of about 500-550.

Title: Speech recognition device
Inventor: KOYAMA MOTOAKI
IPC: G10L21/0316
Filed: 1988-06-17
Abstract: PURPOSE:To obtain high recognition performance by detecting the level of the output of a gain controller and controlling the gain of the gain controller according to the level detection result. CONSTITUTION:The gain controller 1 outputs a speech input signal without controlling the gain and a speech recognizing means 2 performs speech recognition without gain control, so the recognition rate is prevented from decreasing under the influence of variation in the level of the speech input signal. The gain controller 1 when receiving a gain control command signal controls the gain according to the level detection result from an input level detector 3 and performs proper gain control over a following speech input signal. Consequently, the gain is constant until the detection of a speech section is finished, so the features of the pattern of the speech waveform are never spoiled and the recognition rate increases. Further, the gain is controlled before a speech recognizing means 2 performs A/D conversion and the dynamic range of an A/D converter can be used effectively, so the recognition rate is improved.

Abstract: PURPOSE: To provide a recording carrier which ensures the specified resolution of a most desired image dot. CONSTITUTION: This flat recording carrier 6 comprises a flat support layer 3 and at least one porous layer 1 which is positioned on at least one of the faces of the support layer 3. The top porous layer 1 is formed of a plastic material, containing no filler, the particles 7 of which are dissolved in their mutually contacting region. Thus a capillary is formed and a coloring material 8 is moved downward passing through the capillary. A receiving layer 2 for the coloring material 8 which diffusively penetrates by capillary action is located under the porous layer 1. These two layers 1, 2 are located above the support layer 3. During printing, the coloring material 8 is moved upto an intermediate layer by capillary action, passing through the top porous layer 1, so that a rapid drying process takes place on the surface of the recording carrier 6.  The transverse spread, i.e., the flow of the coloring material 8 does not occur and therefore, no fouled area is formed at all. Consequently an outstanding image is securely formed.
