IPC: F02M35/116
Filed: 1993-06-16
Abstract: PURPOSE:To improve low speed torque by securing a sufficient air intake passage length, and realize downsizing and weight reduction of upper and lower housings by forming plural passages and both upper and lower side volume parts in parallel with each other, and arranging plural branch pipes extendedly from the bottom surface of the lower side volume part. CONSTITUTION:After air passing through a throttle valve enters first of all from the inlet part 23 of a lower housing 15 in an air intake manifold and passes through the first passage 18, it enters the second passage 24 of an upper housing 16 through a communicating port 26 of a gasket 28. Next, after it enters the upper side volume part 25 from the second passage 24, it reaches respective cylinders in left and right cylinder rows through a branch pipe 21 of the lower side volume part 19. Thereby, since a sufficient intake air passage length can be secured by the respective passages 18 and 24, the respective volume parts 25 and 19 and the branch pipe 21, a turn flow type resonance pipe can be formed. Thereby, resonance is supercharged to a low speed area of an internal combustion engine, and low speed torque can be improved. Shapes of the respective housings 15 and 16 can be made small. Weight of the respective housings 15 and 16 can be reduced.

Filed: 1987-06-11
Abstract: PURPOSE:To improve the adjusting effect of tone quality at the time of hearing by providing a first amplifier which drives a tweeter and a second amplifier which amplifies the speed signal of the tweeter and driving a woofer with the output of the second amplifier. CONSTITUTION:Signals applied to input terminals 1A and 1B are amplified by power amplifiers 2A and 2B for middle-pitched and high-pitched sound and are applied to a bridge circuit including tweeters 3A and 3B. Signals having the speed characteristic of tweeters are obtained in output terminals of differential amplifiers 5A and 5B to which the signal of the bridge circuit is applied. Outputs of differential amplifiers 5A and 5B are added at an addition point 6, and the addition output is amplified by a power amplifier 2C for low-pitched sound to drive a woofer 4. Consequently, only the low pitched sound part which cannot be reproduced by tweeters 3A and 3B out of signals applied to input terminal 1A and 1B is automatically reproduced from the woofer 4, and the frequency characteristic of the signal reproduced from the woofer 4 is arbitrarily adjusted. Thus, a tone quality most suitable for audition is attained.

IPC: B01J47/14
Filed: 1989-06-07
Abstract: PURPOSE:To perform highly efficient raw water softening treatment generating no hardness leakage by a method wherein at least two water softening devices among several ones are connected in a series water passing state by a flow passage and at least one of the remainder is connected in a regeneration state and a standby state by a flow passage and these water softening device are subjected to rotation control. CONSTITUTION:For example, three water softening devices 3A, 3B, 3C are connected in series in a ring form between a raw water supply source and soft water use machinery such as a boiler vessel body. By changing over the flow passages connecting the respective water softening devices, the raw water supply source and the soft water use machinery are connected in series in a water passing state through two water softening devices and the remaining water softening device is connected to a regeneration medium supply line to simultaneously perform a water passing process and a regeneration process. By preliminarily programming the change-over of lines, the water passing and regeneration processes of the respective water softening devices are successively subjected to rotation control. As mentioned above, since the water passing process and the regeneration process are not alternately performed but simultaneously performed, the wastefulness of a regeneration medium and hardness leakage can be prevented.

Title: Recording control system
Inventor: YOSHIDA SHIGEO
IPC: G06F3/06
Filed: 1984-07-16
Abstract: PURPOSE:To attain the continuous recording by recording successively the recording information in a secondary scan at a fixed speed and recording the position on a recording medium as soon as the secondary scan is stopped in case a recording state is not finished in a recording mode. CONSTITUTION:If the writing of the recording information 1 is not through, a memory control circuit 2 stops the output of the store end signal to a control part 6. The part 6 gives an indication for stop of a reading action and at the same time gives a command to a control circuit 5 to stop the drive of a secondary scan motor 8. While the part 6 delivers a reset signal to set the count value of a counter circuit 7 at zero. The circuit 7 counts the pulses sent hereafter from a rotary encoder 9 to obtain a shift amount from a recording position to the final recording position of a recording medium 12. When the medium 12 moves back, the pulses are delivered from the encoder 9 and subtracted one by one from said count value. Then the zero signal is delivered to the part 6 when the count value of the circuit 7 is equal to zero. Then the drive of a secondary scan motor 8 is stopped, and the recording is possible following the final recording position on the medium 12. Thus the highly economical recording is possible with small capacity of a memory.

Abstract: PURPOSE: To achieve the elimination of adjustment work at the time of assembling by making equal the resistance values of the reference side series resistances of a temperature detecting resistance bridge and the resistance values of its detection side series resistances and temperature detecting element in a temperature control unit of an electric refrigerator, etc.  
     CONSTITUTION: If in a temperature detecting resistance bridge circuit 4 the resistance values of reference side series resistances 10, 11 are equal, the values of the reference potentials are kept constant among the assembled sets despite the use of resistances of different resistance values. Likewise, if the resistance value at the set temperature of a temperature detecting element 12 and the resistance value of the detection side series resistance 14 are made equal, the temperature detecting potentials are also maintained constant and the set temperature becomes the operating temperature. Hence, all required is to connect the resistances 14 of the resistance value equal to the resistance value of the element 12 at a desired temperature and there is no need for temperature adjustment work after assembling. Since the respective resistances and temperature detecting elements of the bridge circuits are classified by resistance values and the classifications of the same resistance values are combined, the operating temperatures are controlled within a permissble range and the need for temperature adjustment after assembling of the apparatus is eliminated.
