Title: Convergence of stepper motor
Inventor: CHIHARA KENICHI
IPC: H02P8/12
Filed: 1980-12-29
Abstract: PURPOSE:To maintain stable convergence regardless of a change of environmental temperature by arranging a temperature sensor adjacent to a viscous damper of a stepper motor to regulate pulse width corresponding to the detected  temperature thereof. CONSTITUTION:Silicon oil generally used for a viscous damper 3 changes its coefficient of viscosity mu 1.9-0.5 (g.scm<2>) when the environmental temperature changed 0-60 deg.C. And accompanied therewith the coefficient of attenuation xsi' of the convergence of the viscous damper 3 changes 0.16-0.32. When a temperature sensor is arranged adjacent to the viscous damper of a stepper motor and a driving circuit is porvided with a pulse width regulating function to become the driving pulse width corresponding to the detected temperature thereof the coefficient of attenuation xsi' can be made to come near to a set value. That is to say that the detected voltage of the temperature sensor is made to the digital signals by the A/D conversion to regulate the driving pulse width by the difference from the reference set temperature.

Title: Detecting device for output torque of internal combustion engine
Inventor: NANBA HIDEAKI
IPC: G01L23/00
Filed: 1986-08-08
Abstract: PURPOSE:To obtain a detecting device which detects engine torque in a real time and is equipped with a fail-safe mechanism even when the output torque of some cylinder is not obtained by providing a pressure detecting means, a sampling means, an output torque arithmetic means, an abnormality deciding means, and a compensating means. CONSTITUTION:A pressure detecting means 3 is provided to each air cylinder 1 and its detection signal is inputted to a sampling means 5. The means 5 samples the detection signal of each specific crank and sends its output to a output torque arithmetic means 7. The means 7 computes in-cylinder mean effective pressure at every 360 deg. crank angle to find the output torque of the internal combustion engine. The abnormality deciding means 9 when deciding a detection signal from the means 3 is abnormal sends the result to a compensating means 11. The means 11 stops the sampling from the means 3 whose signal is found abnormal and use an arithmetic value from another means 3 as a dummy output torque value. Thus, even when the detection signal of any means 3 is abnormal, nearly accurate output torque is obtained and a fail-safe function is displayed.

IPC: G06T5/20
Filed: 1989-07-20
Abstract: PURPOSE:To economically shorten the picture quality processing time and to improve the man-machine interface by executing selectively (n) kinds of product- sum operations at a picture element unit, while switching a parameter to the picture element unit by a value of mask data of an image memory. CONSTITUTION:In order to improve (outline emphasis and graduation) the picture quality of an original image by a product-sum operation, means 30, 31 for setting (n) kinds of parameters, and a means 43 for switching a parameter to a picture element unit, based on a value of mask data are provided in a product-sum arithmetic part 3 of an image processor.

Accordingly, for instance, without using the product-sum arithmetic part 3 two times, the 'outline emphasis' processing and the 'graduation' processing can be executed by single use. In such a way, the time for the picture quality improvement processing can be shortened economically, and the man-machine interface can be improved.
Patent JP-S6080352-A (JP)
Title: Circuit for preventing mis-scanning
Inventor: OONO MASAHIKO
IPC: H04M19/02
Filed: 1983-10-07
Abstract: PURPOSE:To prevent mis-scanning without sacrificing the rising characteristic of a filter by opening the output of a silent trip circuit for a short time by means of a switch in the transition period from the ringing transmission to the silent transmission. CONSTITUTION:When the state is transited from the ringing transmission to the silent transmission, since an electric charge charged in the capacitor of bell circuit in a terminal device SUM and a line distributed capacitor from a ringing signal source RNG is discharged through resistors R2, R3, a silent trip DET is operated erroneously and an output signal pulse might be generated erroneously. Thus, the input of an erroneous pulse to the filter LPF is prevented by opening the output of the silent trip DET by means of the switch SW0 for a short time until a line discharge current is converged at the said transition and it is possible to prevent the generation of the erroneous scanning signal without relaxing the rising characteristic of the filter LPF.

Title: Automatic measuring system for noise exponent of tuner
Inventor: KOBAYASHI SHINROKU
IPC: H04B17/00
Filed: 1980-12-26
Abstract: PURPOSE:To reduce the time of measurement and at the same time to obtain a desired result of analysis from the measurement data, by supplying the noise source output to an electronic tuner when the local oscillation frequency is identical with a desired channel and accordingly measuring the NF value from an IF signal superposed by the random noise. CONSTITUTION:The local oscillation frequency of each channel of an electronic tuner 1 to be measured is read in the form of a code signal of the corresponding local oscillation frequency out of an RAM20 based on the dividing number set previously to a CPU23 to be supplied to a synchronous phase detector 15. At the same time, the local oscillation frequency given from a VC05 is divided into 1/n through a divider 13, etc., and the frequency and the phase are compared between a local signal and the set local oscillation. When no coincidence is obtained, a phase incoming signal is detected. Then a PLL loop is automatically formed until a coincidence is obtained. When the local oscillation frequency is identical with a desired channel, the output of a noise source 8 is supplied to the tuner 1. Then the NF value is measured by an NF measuring device 7 from an IF signal superposed by the random noise and then processed by the CPU23.

Title: Task starting device
Inventor: KAMETANI MASATSUGU
IPC: G06F15/167
Filed: 1986-08-13
Abstract: PURPOSE:To start a task at the highest speed by transforming all sequences needed up to the start of a desired task set between optional processors into hardware excluding 1- or 2-machine instruction needed for a task starting processor to give an instruction to a task start receiving processor for task start. CONSTITUTION:A part or the whole of an interruption vector table of each processor is allocated to a table array 3 itself of a shared memory 2 and not onto a local memory 18. Thus a task starting processor can write the task starting head address itself directly to the interruption vector table of a task start receiving processor. Therefore this processor refers to the table array 3 in an interruption response cycle to shift the processing directly to a desired task after the task start is instructed by an interruption. Thus the overhead of software is minimized. In other words, the 1- or 2-machine instruction instructing the task start is supported by software. While other instructions are all supported by hardware.

Title: Oil burner utilizing hot gas reciprocating engine
Inventor: HASHIMOTO KENJI
IPC: F23L5/02
Filed: 1981-11-25
Abstract: PURPOSE:To enable a combustion air supply fan, an exhaust fan and a convection fan to be rotated by flame by using a hot gas reciprocating engine. CONSTITUTION:After fuel ignition, when a heated part 31 of a hot gas reciprocating engine 5 has been heated sufficiently, a temperature difference is created between the heating space 31 and cooling space 32 so that the working gas in both spaces may repeat a closed cycle including isothermal compression, isochoric heating, isothermal expansion and isochoric cooling. Consequently, a displacer  33 and a piston 34 reciprocate in a cylinder 39 with a phase difference, and the reciprocating motion can be converted by a crank mechanism 38 into a rotary motion so that crank shafts 6, 6' and 6'' may rotate by themselves without any assistance of a starting motor 26. By this arrangement, a combustion air supply fan 7 and an exhaust fan 8 can continuously rotate without consuming a battery  27 thereby enabling stable combustion to be achieved.
