Title: Taper dowel
Inventor: IWATA SETSUO
IPC: E04B1/41
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To provide a taper dowel not producing push-out shearing breakage in a floor board by allowing tension force to some extent since shearing force is transmitted as well as the conventional dowel. SOLUTION: A dowel provides a head part 11b on the edge of a shaft part 11a. A taper is provided so as to be smaller in diameter toward the edge on the head part 11b and the shaft part 11a except for a root part. Thereby since shearing force is transmitted as well as the conventional dowel and tension force can be allowed to some extent, a condition for generating push-out shearing breakage in a floor board can be avoided. In addition, since acting tension force is small, fatigue strength is improved.

Title: Crank case ventilation device for internal-combustion engine
Inventor: OOTAKA SHIYOUICHI
IPC: F01M13/04
Filed: 1984-03-15
Abstract: PURPOSE:To vent the blow-by gas in crank case or head cover effectively by separating the oil compenent of blow-by gas even in the upstream side and the downstream side of PCV valve while evaporating the fuel component and feeding to the intake system without loss. CONSTITUTION:The blow-by gas in a crank case under operation of engine will flow through a communication path 6 into a headcover 5 to separate the majority of mist oil contained in the blow-by gas in a bleezer chamber 15. Not-separated oil component will flow through PCV valve 21 into the upper expansion chamber 20. Here, the blow-by gas will expand to gasify the fuel component and water mixed into the oil thus to separate the oil component from the blow-by gas. Since both chambers 15, 20 are mounted on a head cover 3 which will be brought into high temperature during engine rotation, only the oil component is separated through heating resulting in returning of fuel component to the intake system without loss.

Title: Fuel supply controller for internal combustion engine
Inventor: TANABE YOSHIYUKI
IPC: F02D41/08
Filed: 1987-03-06
Abstract: PURPOSE:To prevent any drop in engine speed from occurring, by increasing a fuel quantity at the time of detecting a starting demand signal for auxiliary engine driving, and after the elapse of the specified time, starting this auxiliary engine driving. CONSTITUTION:A solenoid-operated fuel injection valve 1 and a throttle bypass valve 6a are installed in a suction passage, controlling them by a control unit 11. When an operation starting demand signal for a car air conditioner 15 is detected by a load switch 13, a compensating signal is transmitted to a solenoid valve 6 driving the bypass valve 6a and feed valve opening is increased, while pulse width of the fuel injection valve is compensated for increase. Afterward, when a fact that engine speed exceeds the specified value after the elapse of the specified time is detected, the air conditioner 15 is operated. With this constitution, any drop in the engine speed at time of a start of auxiliary engine driving is preventable.

Title: Preparation of adduct of urea with hydrogen peroxide
Inventor: TANJI KIMIO
IPC: C07C239/00
Filed: 1982-03-30
Abstract: PURPOSE:In the reaction between urea and hydrogen peroxide, to obtain the titled compound useful for an oxidizing agent as solid hydrogen peroxide, having improved hygroscopicity and stability, by adding gypsum to a reaction system. CONSTITUTION:In preparing an adduct of urea with hydrogen peroxide (PU for short) by reacting urea with hydrogen peroxide, gypsum is added to the reaction system. When PU is dissolved in water, it dissociates hydrogen peroxide having strong oxidizing power, so it is useful as a solid hydrogen peroxide, but it has extremely high hygroscopicity and is deficient in shelf stability. The coexistence of gypseum improves hygrosopicity, and the reason is that not only gypsum is attached to PU but also a new compound with certain bond strength is possibly formed in the structure. Gypsum is inductrially preferably used in the form of dihydrate, and its molar amount is >=0.05 based on urea.

Inventor: TAKAICHI AKIHISA
IPC: A23L27/30
Filed: 1990-02-28
Abstract: PURPOSE:To obtain a readily drinkable low calorie composition not showing a bad aftertaste resulting from addition of inorganic electrolyte while exhibiting excellent taste, containing an inorganic electrolyte component and an organic acid component, by blending stevia extract as a sweet component with inorganic electrolytic cation in a given ratio. CONSTITUTION:A low-calorie drink composition containing an inorganic electrolyte component (e.g. NaCl or KCl) and an organic acid component (e.g. sodium citrate or sodium lactate) is blended with a stevia extract as a sweet component in the following ratio. Namely, the amount of the stevia extract blended is 2-15mg based on mEq/l inorganic electrolytic cation in the component. Consequently, a bad aftertaste such as bitterness, harshness and astringency resulting from inorganic electrolytic cation can be eliminated at once to give a readily drinkable composition having good taste. The component can maintain a good taste for a long period of time without exerting a bad influence on taste stability.

Title: Floating point arithmetic system
Inventor: ASANO SADAJI
IPC: G06F7/50
Filed: 1988-03-03
Abstract: PURPOSE:To speed up floating point addition/subtraction by detecting a normalizing quantity from operand data before digit adjusting and preventing round processing in case of the normalizing quantity of >=1 digit when the round instruction of an instruction word comes. CONSTITUTION:Registers 1 and 2 store an operand 1 and an operand 2, respectively. By the respective high order (n) bits [(n)is an integer >=2] of first and second operands before digit adjusting, it is detected that the shifting quantity of the normalization of the result after addition/subtraction of the both operands is zero digit, only when a round instruction comes, and the shifting quantity is detected to be zero digit, round processing is executed, and when it is not zero digit, the round processing is not executed. Thus, the overhead of the round processing is reduced as little as possible, and high speed operation is attained.

Title: Thermal head
Inventor: OTA SHIGENORI
IPC: B41J2/335
Filed: 1989-03-01
Abstract: PURPOSE:To properly transmit an electrical signal to an integrated circuit from an outside line and to constantly perform normal printing by bonding a head substrate composed by arraying a plurality of heating resistors and a flexible wiring substrate used for connecting the heating resistors to the outside line with a soft adhesive possessing an adhesive strength under shear less than a specific value. CONSTITUTION:The head substrate 34 equipped with the heating resistances 32, the wiring substrate 35 and a supporting plate 37 are bonded together with the soft adhesive 50. The under-shear adhesive strength of adhesive used for the soft adhesive 50 is 25kg/cm<2> or below. Consequently, the temperature of the heat substrate 34 and wiring substrate 35 is elevated to a high level, and even if both of the substrate are different from the supporting plate 37 in the thermal expansion the difference is absorbed by deforming the soft adhesive 50, whereby the thermal head is never deformed. If the temperature of the head substrate 34 and wiring substrate 35 is elevated to develop the difference in thermal expansion, the difference is absorbed by the deformation of the wiring substrate 35, since the wiring substrate 35 has less thickness and flexibility. Accordingly, the terminal 47 of the wiring substrate 35 is not separated from the outside terminal 43 of a conductor 44 provided on the head substrate 34.
