Title: Sound reproducing system
Inventor: YAMAMOTO MITSUHIRO
IPC: H04R3/04
Filed: 1990-02-27
Abstract: PURPOSE:To enhance a desired frequency band by attaching an electroacoustic transducer to a speaker, and cutting the signal of the undesired frequency band of an output signal from the speaker, and amplifying and reproducing only the signal of the desired frequency band. CONSTITUTION:Microphones 3, 4 are attached to rear speakers 1, 2, and simultaneously, a case 6 is installed on a board between the rear speakers 1, 2 so that the opening part of its duct 16 faces a driver seat side. On the other hand, at the same time as power supply is acquired by inserting a plug 19 into a cigar lighter so as to drive a car stereo, a switch 10 is turned on, and this system is operated as well. Thus, the microphones 3, 4 pick up the signal from the rear speakers 1, 2, and send it to an LPF circuit 7. The LPF circuit 7 lets only a low frequency signal set beforehand pass through, and sends this signal to a booster amplifier 8. After the booster amplifier 8 amplifies it into sound volume set by a volume 11, it drives a woofer speaker 9 by this signal.

Title: Preparation of alpha-halogeno-beta-alanine
Inventor: MITA RIYUUICHI
IPC: C07C67/00
Filed: 1979-04-18
Abstract: PURPOSE: To obtain the title compound, useful as an intermediate of amino acids such as serine or pharmaceuticals, in a short process, by adding ammonia to an α-halogenoacrylonitrile, and hydrolyzing the products without separation.  
     CONSTITUTION: Addition of ammonia to an α-halogenoacrylonitrile forms an α- halogeno-β-aminopropionitrile, which is then hydrolyzed with a mineral acid without isolation to prepare an α-halogeno-β-alanine or its mineral acid salt. The excess ammonia is preferably removed before addition of the mineral acid. The product can be easily separated, since the protection of the amino group of the intermediate is not necessary.

Title: Toroidal type continuously variable transmission
Inventor: INOUE EIJI
IPC: F16H61/00
Filed: 1996-02-09
Abstract: PROBLEM TO BE SOLVED: To provide an ideal operating performance by compensating a target gear ratio according to a torque deviation between a target input torque and an actual input torque in a toroidal type continuously variable transmission which is provided with a pair of power rollers generating a gear ratio according to a change in inclination angle relative to input and output disks. SOLUTION: A toroidal type continuously variable transmission detects the hydraulic pressure of oil in the cylinder chambers 8a and 8b of a hydroulic cylinder which displaces a trunnion 4 in an inclination axis direction, corrects a target gear ratio by a controller 25 based on the detected values, and operates a spool valve 10 so as to change the position of the trunnion 4 in inclination axis direction for the control of the gear ratio. Namely, a controller 25 detects a pressure difference with each hydraulic pressure acting on the cylinder chambers 8a and 8b, and calculates an actual input torque as a function of the pressure difference and gear ratio. Then a difference with a target input torque is obtained based on an output from an accelerator pedal sensor 20 and, when the difference thus obtained is negative, the target gear ratio is compensated to the speed increasing side.

Abstract: PURPOSE:To reduce a harmful component in exhaust gas from an engine and obtain its stable combustion condition, by setting the first and the second supply time in accordance with a change condition of a detection level and decreasing a supply quantity of secondary air in the second supply time when the engine being in a deceleration condition is discriminated. CONSTITUTION:If an engine being in a deceleration condition is discriminated from a change value DELTAPBA of the intake absolute pressure PBA, a supply device, opening an electromagnetic opening and closing valve 9 with valve opening duty ratio 100% only for a supply time TSH1 corresponding to the change value DELTAPBA, supplies secondary air to the engine. And if a time elapses by the supply time TSH1, the valve opening duty ratio gradually decreases from 100%, while if the time elapses by a time TSH2, the valve opening duty ratio reaches 0%. Accordingly, the device, supplying the secondary air a little early anticipating a change of air-fuel ratio in the initial time of deceleration and preventing the air-fuel ratio from becoming overrich while gradually decreasing a quantity of the secondary air also in the latter period of the deceleration, controls the air-fuel ratio almost in a follow-up manner to the base air-fuel ratio of a carburetor.
