Title: Turbo multistage blower
Inventor: TANAKA TADAO
IPC: F04D29/44
Filed: 1987-08-10
Abstract: PURPOSE:To reduce ventilating resistance as well as to improve blast efficiency by forming an interspace between adjacent impellers so as to widen toward the central part from the outer circumferential part in order, in the case of a radial straightening guide installed a casing outer end face between these adjacent impellers. CONSTITUTION:A turbo multistage blower has each multistage turbo impeller 4 inhaling air from the central part and exhausting it out of the outer circumferential part, and it is provided with each radial straightening guide 18 on a casing outer end face between adjacent impellers 4. In this case, each straightening guide 18 is formed so as to widen the adjacent mutual interspace toward the central part from the outer circumferential part in order. That is to say, in each straightening guide 8, an air inlet angle alpha of the outer circumferential part is set to an obtuse angle of eight degrees or so while a turning angle of an air flow is made smaller, and the outer circumferential part is bent at curvature R1 of 95% or so in a peripheral radius D/2, while as far as a small diametral part, it is set to smaller curvatures R1, R2, and the final curvature R3 is set down to 28% of the peripheral radius S/2, thus it is bent and formed.

Title: On-vehicle air cleaner
Inventor: IMAI HIDETOSHI
IPC: B01D46/42
Filed: 1992-07-27
Abstract: PURPOSE:To indicate the appropriate time for replacing a filter by issuing an alarm for the filter replacement after a fixed time of after an actual operating time which the fixed time is multiplied by a certain factor. CONSTITUTION:Since the service life of an activated carbon filter of such size that it can be mounted on an on-vehicle air filter is usually about one year after unsealing, a timer in a microprocessor 4 is set so that a light emitting diode 7 may be lighted, for example, at a time when one year elapsed after the energization. The time when the light emitting diode 7 is illuminated by the information on operating time to a memory element 5 is set at the time which the energized time is multiplied by a certain factor. As a result, when the air cleaner is first installed by the user, a backup battery 9 is connected, thereby the light emitting diode is lighted after one year at most from that time.

Title: Voltage controlled amplifier
Inventor: NAKAZAWA SATOSHI
IPC: H03G3/10
Filed: 1996-07-09
Abstract: PROBLEM TO BE SOLVED: To make the level change of a control voltage supplied to a voltage controlled amplifier(VCA), which is constituted so that the voltage level of the control voltage can be switched by means of the rotary switch, nearly continuous at the time of switching the rotary switch. SOLUTION: Voice signals from a source 1 are supplied to a loudspeaker 4 through a following amplifier 3 after the level of the signals is adjusted by means of a VCA 2. The amplification factor G of a VCA 1, namely, the voltage level of the control voltage CV supplied to the control terminal 2a of the VCA 2 is switched by means of a rotary switch 6. When the rotary switch 6 is switched, the output voltage VS of the switch 6 abruptly changes, but the voltage level of the control voltage CV, accordingly, the voice level of the loudspeaker 4 does not change abruptly even when the switch 6 is switched because the abrupt change of the voltage VS is relaxed by means of a low-pass filter 7.

Title: Timer stand-by device
Inventor: UMEMOTO KATSUHIKO
IPC: G11B31/00
Filed: 1981-12-14
Abstract: PURPOSE:To listen a reproduced sound of a tape during timer reproduction without reference to the position of a selector, by allowing the selector to change to a tape position automatically during the timer reproduction. CONSTITUTION:When a timer stand-by switch SW1 is placed at a sound recording position, the tape input circuit of a selector 4 is prevented by a diode D1 from attaining a level L, so the selector 4 never changes to a tape position. Then when the switch SW1 is placed at a reproduction position, the tape input circuit of the selector 4 and the reproduction input circuit of a logical control 5 both attain the level L, so the motor of a tape deck is driven to set a reproduction state and the selector 4 also changes to the tape position at the same time.

Abstract: PURPOSE:To improve the carrying force of the transfer material of a transfer drum disposed opposite to the photosensitive drum of a copying machine. CONSTITUTION:The transfer drum 60 has a pair of ring members attached to a rotary shaft and both ring members are connected with a tie-plate 640. Both side parts of a dielectric sheet 630 made of flexible resin are adhered to the ring members.
