Title: Method for estimating torque developed from engine
Inventor: SHIMIZU HIROKAZU
IPC: G01L3/00
Filed: 1997-07-07
Abstract: PROBLEM TO BE SOLVED: To enhance the estimation accuracy of the developed torque based on the angular acceleration Δω of an engine. SOLUTION: Angular speed is detected in two different sections of the expansion stroke and the angular acceleration Δω is operated, based on the detection results (S2). Meanwhile, correction terms OMNEHA and OMNEHB are operated based on the rotational speed of engine Ne (S3) while correction terms OMBOHA and OMBOHB are operated, based on the boost (S4). An estimated value of torque T is then calculated (S5) according to the following formula; T=Δω×(OMNEHA×OMBOHA)+(OMNEHB+OMBOHB).

Title: Reproducing device of fm modulation sound signal recorded magnetically
Inventor: KOUNO MICHIO
IPC: G11B20/06
Filed: 1983-09-28
Abstract: PURPOSE:To detect the lack or attenuation of a sound carrier signal, and to compensate it by providing a switching circuit for introducing the output of a phase locked loop circuit into a demodulator as an artificial sound carrier signal instead of a sound carrier signal when it does not exist. CONSTITUTION:A demodulator 7 demodulates an FM-modulated sound carrier wave and outputs a reproducing sound signal 8. A PLL (phase locked loop) oscillating circuit is constituted of a phase comparator 10, low-pass filter 11, VCO (voltage controlled oscillator, variable voltage control oscillator) 12, and an (n) frequency dividing circuit 14, and it is controlled by an output of an (n) frequency dividing circuit 9. An inputted reproducing sound carrier wave signal is usually inputted to the demodulator 7 through a switch 6, demodulated and goes to the reproducing sound signal 8. When the lack or attenuation being below a prescribed level is detected in the inputted reproducing sound carrier wave, the switch 6 is switched to B from A, and an artificial sound carrier wave by the PLL oscillating circuit is led into the demodulator 7 instead of the reproducing sound carrier wave.

Title: Secondary surveillance radar equipment
Inventor: SHIGIYOU CHIKAAKI
IPC: G01S7/40
Filed: 1993-06-28
Abstract: PURPOSE:To easily install a target responding device for confirming the positional accuracy of an SSR (secondary supervisory radar equipment) when the SSR is operated as an independent station. CONSTITUTION:Transmitting signals conventionally modulated with a response signal equivalent to the response information from a remote transponder (RPM) are transmitted as radio waves Wb through a monitor transmitting section 3 and monitor antenna 1 based on a monitor transmission control signal C2. An SSR antenna 6 receives the radio waves Wb and intermediate-frequency signals S1 processed through a circulator 10 and receiving section 7 are inputted to an intermediate-frequency signal processing section 8. The section 8 divides the signals S1 into the received signals of an SSR and monitor receiving signals based on a switching control signal C3 and, at the same time, controls the phase and amplitude of the monitor receiving signals based on a phase control signal C4 and amplitude control signal C5. In addition, Fourier transformation is performed for replacing the characteristics of short-distance reception with those of long-distance reception. Thereafter, a signal processing section 9 processes the video signals of the monitor receiving signals and outputs SSR target data S7.

Title: Auto-focus mechanism for survey instrument
Inventor: NAKAMURA YUTAKA
IPC: G01C15/06
Filed: 1999-06-28
Abstract: PROBLEM TO BE SOLVED: To realize auto-focus of a staff without requiring a significant modification of a survey instrument by providing a fine adjustment means for determining the distance to the staff based on a pitch determined by a pitch operating means and moving a focus lens to a position corresponding to the distance. SOLUTION: A line sensor 24 converts the received image of a staff into an electric signal which is amplified through an amplifier 25 and then subjected to sample & hold in synchronism with the clock signal of a clock drive r26. It is then subjected to A/D conversion and stored in an RAM 28. A microcomputer 3 determines the widthwise dimension of each mark based on the signal stored in the RAM 28. Subsequently, the height h of collimation is determined based on the widthwise dimension of the mark and a table value prestored in an ROM 31. A drive circuit 29 controls operation of the line sensor 24. Since the optical axis of a collimation optical system is aligned with that of an image optical system, collimation point on the staff matches that of the image optical system. Survey results are displayed at a display section 32.

Title: Video tape recorder
Inventor: YOSHIMURA YASUHIKO
IPC: G11B15/02
Filed: 1987-07-23
Abstract: PURPOSE:To prevent a malfunction during an editing by locking the operation of a control switch other than that of reproduction when an editing control switch on the reproducing side of a video tape recorder VTR is operated at the time of the editing. CONSTITUTION:By operating control switches 3a and 3b, a VTR 1 on the reproducing side is set to an editing reproduction mode, and a VTR 2 on a picture recording side is set to a picture recording mode. When an editing switch is operated to ON, a control circuit 4a locks a switch operation by a control key other than a play key. Consequently, even when the stop key, etc., of the switch 3a is operated during the editing, the VTR 1 does not malfunction, and the editing reproduction continues. When a tape is stopped from the editing reproduction mode, the editing switch is turned off, and then the stop key is pushed. Thus, even when the control switch is operated erroneously during the editing, the malfunction of the VTR on the reproducing side is prevented.

Filed: 1988-07-21
Abstract: PURPOSE: To obtain a network provided with a multi-node ring useful for transmitting a digital sound by providing each node with a means for canceling all packets transmitted from the node after one circulation of a ring. CONSTITUTION: Series data transfer between nodes is executed through a multi- node optical fiber 2 and an electric-optical converter 3 constitutes an interface.

When a packet is in a 'full' state but the output of an address decoder is 'itself', a switch 17 connects the transmitting register TX to the ring, a packet stored in the receiving regiter is disused and overwritten by a succeeding input packet. The 'itself' packet is destructed in order to prevent the packet from being transmitted along the ring twice or more.
