Title: Single-loop steering machine
Inventor: ONARI YASUKE
IPC: B63H25/24
Filed: 1984-07-09
Abstract: PURPOSE:To reduce the shock to a steering machine by converting an actual rudder angle deviation signal into a signal, which rises at a certain inclination, by means of a buffer simulation amplifier, thereby moving an angle-inclining lever smoothly. CONSTITUTION:When an actual rudder angle deviation signal deltae is given from a subtracter 2 based on an output signal delta0 from an rudder angle commanding device 1, an output signal theta0' is output from a buffer simulation amplifier 5. The signal theta0' is limited by a limiter 9 and then enters a subtracter 10. An integrator 17 and a limiter 18 are placed in parallel with a linear amplifier 16 in order to add the output signal thetaep from the linear amplifier 16 and that thetaeI from the limiter 18. With this, the follow-up accuracy can be improved without increasing the gain of an electric power amplifier 13. In addition, the limit value for the limiter 9 is made greater than the mechanical limit angle so that a steering pump angle-inclining lever 11 abuts on the mechanical stoppers 15A, 15B. With this contrivance, the right and left rudder turning speed can be made constant even when there is variation in friction.

Title: Air-fuel ratio control device for internal combustion engine
Inventor: UCHIKAWA AKIRA
IPC: F02D41/14
Filed: 1993-06-11
Abstract: PURPOSE:To prevent an air-fuel ratio correction control made by an oxygen sensor provided downstream from a catalyst, from becoming an over-correction by being influenced by the oxygen storage effect of the catalyst. CONSTITUTION:It is judged whether the frequency of air-fuel ratio feed back control (S24) on the basis of the output of an oxygen sensor provided upstream from a catalyst is a prescribed value and more or not (S25, S26). When the frequency is the prescribed value or more, it is judged whether or not the number of reversion times (S27) of rich/lean condition detected by the oxygen sensor on the downstream side is a prescribed number of times or more (S28). When it is less than the prescribed number of times, it is inhibited to make correction on the basis of a result detected by the oxygen sensor on the downstream side. Only when the number of reversion times becomes the prescribed number of reversion times or more, air-fuel ratio correcting control in which the detected result of the oxygen sensor on the downstream side is used is carried out (S29, S30).

Abstract: PURPOSE:To prevent a spring from deteriorating, to unnecessitate replacing of the spring in a short period of time, to facilitate the maintenance of the heat exchanger and to eliminate a possibility of leakage of a fluid to be heated, by cooling the spring which applies an independent clamp pressure to a heat transfer tube by the low-temperature fluid to be heated. CONSTITUTION:An exhaust gas of a high temperature exhausted into the inner part of a frame body 1 is flowed, and air and other fluid to be heated of a low temperature are supplied into spaces 9, the fluid to be heated cools a spring 8 which is provided between one side wall surface component 4 of wall surface components 3 and 4 for clamping and holding a heat transfer tube 2, and a frame body 1, and applies an independent clamping force to each heat transfer tube 2. At the same time, the fluid to be heated is preheated by heat transmitted through the wall surface, and is introduced into a preheating chamber 10. The preheated fluid to be heated enters the heat transfer tube 2, and flows into a reversing chamber 13, flowing through the heat transfer tube 2 and being discharged to a heated fluid chamber 12. Meanwhile, each heat transfer tube 2 expands by the heat of the exhaust gas of a high temperature. However, since respective heat transfer tubes 2 are individually clamped and held by surface wall components 3 and 4 slidable in the axial direction, any leakage of the fluid to be heated is not produced.

Title: Method and device for controlling sound volume of one-bit digital signal
Inventor: TAKAHASHI RYUTARO
IPC: H03G3/02
Filed: 1997-05-30
Abstract: PROBLEM TO BE SOLVED: To control with high accuracy the sound volume of analog sound signals, without producing noises at the time of demodulating one-bit signals obtained by delta-sigma modulation. SOLUTION: A clock signal source 3 generates, in advance, a system clock CK having a sufficiently high frequency synchronously to one-bit signals DAT, and a pulse width control signal generating circuit 2 counts the pulses of the system clock CLK by the number, corresponding to the volume value set by means of a volume setting means 4 and causes flip flops 6 and 7 to output pulses only during that period. Since a volume control signal VOLCTL is a binary signal, noise is not produced due to threshold fluctuation, etc., and pulse width errors become the crystal accuracy of the clock CLK.
