Title: Control device for engine with supercharger
Inventor: TAJIMA SEIJI
IPC: F02B37/00
Filed: 1989-01-20
Abstract: PURPOSE:To smooth the connection of the supercharge pressure control when an exhaust cut valve is opened in the high flow quantity area of an engine to operate the second supercharger by flowing a part of the exhaust gas with an exhaust leaking means to give the prerotation. CONSTITUTION:When an operated condition detecting means detects that an engine reaches the high flow quantity area, a switching control means opens an exhaust cut valve to operate the second turbosupercharger. At this stage, a part of the exhaust gas is flowed by an exhaust leaking means, and the prerotation is given to the second supercharger before the exhaust cut valve is opened, and the exhaust cut valve is opened at the time that the rotation is raised. On the other hand, in the low flow quantity area where only the first supercharger operates and the second supercharger does not operate, the exhaust leaking means works as a supercharge pressure control valve, and the operation of a waist gate valve is restrained by a restraining means, and the restraint is cancelled in the second supercharger operating area so that the supercharge pressure control is performed by the waist gate valve. Thereby, the connection of the supercharge pressure control is smoothed, and the fluctuation of the maximum supercharge pressure can be prevented.

Title: Remote control unit of tape recorder
Inventor: KEISHIYUU SEIICHI
IPC: G11B15/04
Filed: 1978-02-06
Abstract: PURPOSE: To perform remote controlling with transmitter and receiver of one system by providing a delay circuit which holds the state of the time when the output signal exists only for a fixed time even if the output signal from a demodulating circuit annihilates.  
     CONSTITUTION: When the signal of the frequency corresponding to an arbitrary time recording command is transmitted by depressing the recording command key R' of a transmitter 1, the transmission carrier having been modulated is demodulated in the demodulating circuit 3 of a receiving part 2 and while the recording command signal is being transmitted, the emodulated signal corresponding to this is applied from terminal 3c to a delay circuit 6. The circuit 6 transmits the signal from the circuit 3 immediately to a recording commanding switching circuit 7 to close this, thus maintaining the state wherein the output signal exists only for a fixed time even if the signal from the circuit 3 annihilates. Hence, when a play command signal is transmitted in place of the recording command signal within this fixed time, the circuit 3 applies the demodulated signal corresponding to this to the play commanding switching circuit 5 from terminal 3b. Thereby, remote controlling may be performed with the transmitter and receiver of one system.

Title: Data demodulating device
Inventor: ENDO KAZUHITO
IPC: G11B20/10
Filed: 1989-01-20
Abstract: PURPOSE:To automatically and speedily put a PLL circuit in the locked state even if the PLL circuit is unlocked by switching a counted value to be decided as a synchronizing signal when the PLL circuit is in the unlocked state and enabling synchronous detection. CONSTITUTION:When the PLL is unlocked, the specific value of a detecting circuit 23 is switched selectively to other predetermined values, e.g. '3' and '7'. The specific value is put back to the original value (e.g. '5') after the synchronizing signal is obtained correctly and the PLL3 corrects the frequency of a clock almost to a target accordingly. Namely, when the PLL is unlocked, the switching of the specific values in the order of (b) (e.g. b=3)   (a) (e.g. a=5), and (c) (e.g. c=7)   (a) is carried on periodically until the PLL enters the locked state. Consequently, even if the PLL is unlocked temporarily, the PLL can be put in the PLL locked state speedily as long as the correct received signal is obtained and the correct clock extraction is possible, so biphase demodulation can be performed by using this clock.

IPC: G02B7/04
Filed: 1998-01-08
Abstract: PROBLEM TO BE SOLVED: To obtain an inexpensive high-quality AF lens barrel where a distance adjusting barrel can be manually adjusted without requiring manual switching operation and which can be always adjusted by providing a clutch mechanism connected to a motor only when the rotational power of the motor is applied at the time of automatic focusing so as to transmit the power of the motor to the distance adjusting barrel. SOLUTION: This automatically acting clutch mechanism 11 is provided between the motor 12, and a pinion 9a and a reduction gear train 9b to 9d which are a transmission mechanism, so that the switching operation between connection and interruption need not be performed severally at the time of manually adjusting a distance. Therefore, even when manual power is applied to a manual adjusting barrel 6 and transmitted to the motor 12 side in a reverse direction, it is not transmitted to the motor 12 side but makes a clutch shaft 10 idly rotate from the pinion 9a. Namely, the mechanism 11 is connected to the motor every time ordinary control operation of the motor 12 for the normal rotation and the reverse rotation of the motor 12 is performed, and driving for focusing is realized.  When the motor 12 is stopped, the mechanism 11 is disconnected and the manual adjustment of the barrel 6 is easily performed.
