Patent JP-H08318848-A (JP)
Title: Brake booster
Inventor: IKEDA MASAHIRO
IPC: B60T13/573
Filed: 1995-05-29
Abstract: PURPOSE: To furthermore make the device simple in structure, and reduce its cost much while the pressure changing chamber of the brake booster is being released to atmospheric pressure at a stretch. CONSTITUTION: At the time of abrupt braking, by the quick footing of a brake pedal, a valve plunger 20 is quickly advanced so as to be brought into contact with the shaft section of a first piston 33, and thereby the first piston 33 is quickly advanced. This constitution thereby allows the tip end of a second cup seal 39 to pass through the opening end close to the first piston 33 of a first fluid flow path 31 before an output shaft 32 is outputted, namely, before pressure is built up in a first fluid chamber in which fluid is to be filled. As a result, the first fluid chamber 36 is communicated with a second fluid chamber 37 by way of a first and a second fluid flow paths 31 and 34, and fluid in the first fluid chamber 36 flows in the second fluid chamber 37.  This constitution thereby allows a reaction mechanism by the pressure of the first fluid chamber 36 to be temporarily suspended, and also allows the output of the brake boostor to be raised up to its full loading at a stretch.

Filed: 1995-05-30
Abstract: PURPOSE: To improve the accuracy of sensing a flame failure and to enhance the safety by storing a flame rod level before forming a flame, and comparing it with a flame failure level set newly based on it. CONSTITUTION: A flame rod level at the time of non-combustion before a flame is formed is detected by a flame rod level detector 1, and stored in a memory 3. It is compared with a flame failure level reference value set to a flame rod reference unit 2, and if it does not exceed the flame failure level reference value, the reference value is set to a flame failure setter 4. On the other hand, if it exceeds the flame failure reference level, a predetermined value is applied to the stored rod level, and set to the setter 4 as the new flame failure level, and combustion is controlled with it as the flame failure level until a pump 7 is next turned OFF. Even if the flame rod output from the detector 1 has an initial irregularity or an irregularity due to the external cause, the operation of the flame failure is guaranteed, thereby obtaining the burner of higher safety.

Title: Semiconductor integrated circuit device
Inventor: NISHIZAWA HIROTAKA
IPC: H01L29/73
Filed: 1989-05-26
Abstract: PURPOSE:To reduce a parasitic capacity formed between a collector region and a semiconductor substrate and to increase an operating speed of a bipolar transistor of a vertical structure by a method wherein a circumferential edge length of a buried-type collector region is shortened and a p-n junction area of the buried-type collector region and the semiconductor substrate is reduced. CONSTITUTION:In a p<+>-type semiconductor region 11 which is used as a graft base region prescribed by a base opening 9, a corner part of a square shape is reduced as shown by oblique lines marked with a symbol 11A. Consequently, a total circumferential edge length of the p<+>-type semiconductor region 11 used as the graft base region is shortened. As a result, a p-n junction area to an epitaxial layer 2 as an n-type collector region is reduced by a portion corresponding to the reduced corner part. That is to say, in an interelement isolation insulating film 5 surrounding the circumference of the p<+>-type semiconductor region 11 used as the graft base region of a p-type base region, corner parts constituted of a square shape are reduced in the same manner as those of the base opening 9 and the p<+>-type semiconductor region 11.

Title: Amplifier of force by means of magnetic force
Inventor: YOSHIDA SHIGESADA
IPC: F16H49/00
Filed: 1982-07-28
Abstract: PURPOSE:To effectively utilize the force of nature, by a method wherein, by use of a magnet and by simultaneous comnination use of repulsion and attraction, through application of the fact in that a force, being larger than a force being given, is obtainable, such forces as weak light, heat, wind, water, electricity, etc., are converted into a large force. CONSTITUTION:Since a fixed magnet 2 on the lateral wall 37 side and a pole inversion magnet 1 make contact with each other at polarities different from each other, an inner N-pole and S- pole are depolarized, and only an outer S-pole and N-pole are independently in a repulsion relation. A fixed magnet 2' and a pole inversion magnet 1' on the rotary shaft 13 side are also positioned in the relation in that the attraction is exerted only between the two outer poles thereof. In a position A, attraction between 4 poles is exerted on the upper, and simultaneously, repulsion between 8 poles on the lower, resulting in producing a 4-repulsion force. In a position B, a 4-attraction force, being total attraction less total repulsion, is exerted, in a position C, a 4-repulsion force is exerted in like manner, in a position D, a 4-attraction force is exerted in like manner, and this causes said forces, in order, to turn a rotary shaft 13. The larger the number of such magnets disposed are, the larger the number of the poles, which contact at different polarities and are depolarized, and the number of poles, which contact each other at the same polarity and are independent, become, and both repulsion and attraction become large, resulting in enabling energy-saving.

Title: Device for detecting pachinko ball
Inventor: TAKEMOTO TAKATOSHI
IPC: A63F7/02
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To provide a detecting device which is resistant against electric noise and which can accurately judge the passage of pachinko balls. SOLUTION: An emitting light source 24 and one end face 23a of an optical fiber 23 are counterposed at bath sides of a passage of balls. The light from the light source 24 is led to a photoelectric current converter 26 through the optical fiber 23. And hence, even if the light from the emitting light source 24 goes around the ball and reaches the end face 23a of the optical fiber 23 when the ball passes, diagonal incident light onto the end face is reflected and it does not reach the photoelectric current converter 26. As a result, the passing ball can be accurately detected without influence of the light going around the ball. And as information showing whether a ball has passed or not is transmitted in just state the light was in that time, the detecting device is not affected by electric noise or the like.

Title: Preparation of drink utilizing distillation residue of whisky
Inventor: KANEKO SHIYOUHEI
IPC: A23L2/38
Filed: 1982-07-30
Abstract: PURPOSE:To eliminate the extremely unagreeable odor of the distillation residue of whisky, by extracting the residue under heating and filtering the extract. CONSTITUTION:The distillation residue of whisky is extracted at 75-90 deg.C for 20-60min, and the extract is concentrated at about 50 deg.C. The microbial cells, suspending materials, and other foreign materials are removed from the concentrate to obtain clear filtrate, which is added with an acidulant to obtain the objective drink. The taste and flavor of the fermentation residue of whisky can be remarkably improved by heating; however, the temperature of the heat- treatment should be suppressed to <=90 deg.C to minimize the degradation of vitamins and other active components. The extraction for <=20min results in insufficient extraction, and when the extraction time exceeds 60min, the unagreeable odor is transferred to the filtrate. The concentration is preferably carried out until the volume of the distillation residue is reduced to 1/2-1/4 of the original volume, using a vacuum evaporator under reduced pressure. Since the concentration at >=65 deg.C results in the coagulation of a part of the proteins, it is preferable to concentrate at a temperature as low as possible, usually at 45-55 deg.C.
