Title: Mounting device of engine
Inventor: FUKUSHIMA MASAO
IPC: B60K5/12
Filed: 1980-04-17
Abstract: PURPOSE: To prevent stuffy sounds by a method wherein an elastic body connecting two coupling bodies of the captioned device for an automobile and a vibrating system transmitting a force which is inverse in phase to that of the elastic body in a stuffy-sound generating region are added to the coupling bodies and two systems are made to interfere with each other.  
     CONSTITUTION: The coupling bodies 25 and 27 are connected by the 1st elastic body 28 having a prescribed spring constant. On the other hand, the coupling body 25 is connected to the 1st mass damper 32 through the intermediary of the 2nd elastic body 33, the coupling body 27 to the 2nd mass damper 35 through the 3rd elastic body 36 and the 1st mass damper 32 to the 2nd mass damper 35 through the 4th elastic body 37, respectively, and the vibrating system 36 is constituted by the 2nd, 3rd an 4th elastic bodies 33, 36 and 37 and the 1st and 2nd mass dampers 32 and 36. And the phases of a force transmitted by the elastic body 28 and of a force transmitted by the vibrating system 36 are made inverse to each other in the region where the stuffy sounds are generated. By this constitution, the forces of two vibrating systems 28 and 36 interfere with each other, whereby the stuffy sounds generated at the time of high-speed running can be prevented.

Title: Transmission
Inventor: MIYAO TAKAYUKI
IPC: F16H3/72
Filed: 1986-03-10
Abstract: PURPOSE:To make it possible to shift a first gear speed to a second gear speed under a hot shift condition, and thereby improve the acceleration performance upon changing a speed, by providing a gear transmitting system through a clutch in addition to a main driving system including a continuously variable transmission and a steppedly variable auxiliary transmission connected in series thereto. CONSTITUTION:A main driving system including a continuously variable transmission 2 and a steppedly variable auxiliary transmission 3 connected in series thereto is provided between an input shaft 1 and an output shaft 5. A gear transmitting system is associated with the main driving system through a free wheel clutch 4. As a result, a power transmission course where the power from an engine is transmitted through the input shaft 1, the continuously variable transmission 2 and the steppedly variable auxiliary transmission 3 to the output shaft 5 is shifted to another power transmission course where the power is transmitted through the input shaft 1, the clutch 4 and the gear transmitting system to the output shaft 5. As the shift of the power transmission course is conducted simultaneously with a change in gear speed, the gear speed shift control may be effected under a so-called hot shift condition without a reduction in power. Accordingly, the acceleration performance of a vehicle upon changing a speed may be improved.

Title: Semiconductor circuit
Inventor: NAKANO MASASHI
IPC: H03K19/0948
Filed: 1985-03-15
Abstract: PURPOSE:To eliminate a period in which both TRs conduct simultaneously, and to reduce a transient current of the time when an output is inverted, by executing the gate driving of a P-ch transistor (TR) and an N-ch TR of an output stage by each separate circuit, and putting a delaying circuit in one circuit. CONSTITUTION:An input terminal 1 is connected to a control terminal of switches 4-7 and also a delaying circuit 2. The switch 4 and 7, and 5 and 6 are interlocked and operated. In case an input voltage is a '0' level, the switches 4, 7 conduct, the switches 5, 6 are cut off, and in case the input voltage is '1' level, said switches are operated in reverse from the foregoing. In case the input voltage is varied from '0' to '1' level, the switches 4, 7 are cut off and the same 5, 6 conduct. Subsequently, a signal passed through the delaying circuit 2 passes through the switch 5, and a P-ch TR 8 becomes a cut-off state. At this time point, an N-ch TR 9 is in a cut-off state. Next, a signal passed through a delaying circuit 3 passes through the switch 6, makes the N-ch TR 9 conduct, and a voltage of an output terminal 10 is inverted.

Title: Phase comparator
Inventor: ICHISE TAAKI
IPC: H03D13/00
Filed: 1978-04-28
Abstract: PURPOSE:To enable to increase the phase lock performance, without causing discontinuous point, by corresponding the output performance to the phase difference with excellent linearity through the provision of the means producing the phase difference signal. CONSTITUTION:At the period T1 in which the reference frequency signal fR(a) is lead in the phase sufficiently from the variable frequency signal fs(b), AND1 is established and the output of FF1 is given to the transistor T1 as the phase difference signal (c), the capacitor C1 is charged up (f), and the output voltage (g) proportional to the phase difference is produced. Further, at the period T2, when the phase difference between fR and rs is small, the output voltage (g) is decreased by the lowering in the charge up voltage (f) of C1. That is, when fR is lag to fs in phase, the output voltage is zero, and as the phase advances, the output voltage is increased and it saturates finally. Thus, by using the slope not saturated as the phase lock, the output performance corresponding to the phase difference can be corresponded with good linearity and no discontinuous point is caused.

CONSTITUTION:A fan 3 is actuated by switch 17-on to permit air to be supplied into a car room. When a compressor switch 16 has been turned off by that time, contacts of relays 20 and 21 close and an electromagnetic solenoid 15 is manually closed and opened by means of an inside-outside air switch 18 allowing an inside-outside air door 2 to be opened in the direction of an internal air intake port 1b and fresh air intake port 1a. When the compressor switch 16 is turned on, a control device 13 is actuated by a detector 14, and then an input 20 a is turned off, thereby the output of a relay 20 being turned on allowing the output of a relay 21 to be turned off to close the contact to cause the solenoid 15 to be deenergized to provide the internal air intake. Consequently, the inside-outside air door is linked to the compressor 90 that the internal air intake may be effective instead of the configuration of external air intake provided that the compressor is off, and external air intake is effective only when said compressor is on.

Thereby, it is possible to know the relaxation time of the nucleus depending on the specified nucleus spectral peak A and the size of the interaction between the nuclei. Moreover, the distance therebetween and the kinetic velocity of a molecule can be made known.
