Title: Hydraulic booster and brake hydraulic pressure boosting system using the hydraulic booster
Inventor: KOBAYASHI MICHIO
IPC: B60T13/12
Filed: 1998-02-06
Abstract: PROBLEM TO BE SOLVED: To provide an output larger than a normal output with a simple structure and with a specified or more input. SOLUTION: Until a hydraulic pressure inside a power chamber reaches a first specified pressure and the right end of a reaction piston 20 touches the step part of an input shaft 18, a jumping action is performed at a larger servo ratio. Until the hydraulic pressure inside the power chamber reaches a second specified pressure, a selector valve is set at a first position I. As a result, a reaction chamber 41 is connected to a reservoir 33 at the atmospheric pressure. Under this condition, a normal brake control is performed at a small servo ratio. When the hydraulic pressure inside the power chamber reaches the second specified pressure, the selector valve is set at a second position II by its hydraulic pressure. As a result, the pressurized liquid is introduced from the power chamber to the reaction chamber 41.  Because the hydraulic pressure inside the reaction chamber 41 acts on a step part formed with the reaction piston 20 and an input shaft 18, a servo ratio becomes larger and a servo-control at higher servo ratio can be performed. Thus a hydraulic booster provides a reverse double-stage servo characteristics.

Title: Nitrogen oxide sensor device
Inventor: YAMAZOE NOBORU
IPC: G01N31/00
Filed: 1994-02-23
Abstract: PURPOSE:To measure both of NO2 and NO with high sensitivity by converting NO to NO2 in the previous stage of a flue. CONSTITUTION:From an inlet of a flue 2 through which NOx gas passes, a reducing gas catalyst 5, a converting catalyst 4 converting NO to NO2, and a nitrogen oxide sensor 3 are arranged in this order. NO2 and NO diluted with synthetic air to 5-200ppm are passed through the flue 2 at 200-1000ml/min. In this process, the catalyst 5 completely oxidizes the reducing gas if H2 and CO are used as coexistent gas, and electromotive force of the sensor 3 is measured by an electrometer without any influence of the reducing gas. In the catalyst 4, converting reaction from NO to NO2 is carried out through the catalyst put between silica wool, and NOx is detected by using a chemiluminescence type NOx. In this way, NO can be also measured with high sensitivity, while highly sensitive measurement of NOx can be carried out without being affected by coexistent gas.

IPC: G10H1/26
Filed: 1978-03-07
Abstract: PURPOSE: To perform accompaniment play with ease by subsequently reading out the plural preset accompaniment fundamental notes to form accompaniment tone signals and producing the sounds according to rhythm patterns.  
     CONSTITUTION: The accompaniment tone fundamental note, chord kinds, having been preset in a chord assignment mechanism 11 are read out at the periods determined via ring counter 12. AS a result, the fundamental note inforamtion and the pitch information relating to the selected fundamental notes are applied from fundamental note etc. encoders 13 thru 17 become the pitch signals corresponding to the chord information applied to a selector 18 and are applied to sound source circuits 19 thru 21 for fundamental notes, etc. The sound source signals generated by these circuits 19 thru 21 pass through gate circuits 22a thru 22c, 24, 27a and 27b and become fractional chords, chord sounds, base sounds. On the other hand, the desired rhythm pattern signals selected in a rhythm selection circuit 38 by a decoder 35, rhythm pattern forming circuit 36, selector 37 control the opening and closing of the circuits 22a thru 22c, 24, 27b. Hence, the accompaniment tones may be automatically played readily through presetting without the operation of accompaniment keyboard at the melody playing.
