Title: Parmanent magnet
Inventor: MIZOGUCHI TETSUHIKO
IPC: H01F1/04
Filed: 1991-02-06
Abstract: PURPOSE:To obtain excellent magnetic and mechanical characteristics, by constituting a magnet of alloy which contains martensite transformation phase, as a constitution phase. CONSTITUTION:Martensite transformation phase is contained. In this case, it is desirable for crystal grains constituting the martensite transformation to be anisotropically arranged. It is desirable for the alloy to contain at least one kind out of Fe, Co, Ni and Mn as the constituent element. Martensite is a metastable structure formed by non-diffusive transformation at a temperature lower than or equal to a specified value, when metal or alloy is quenched from a temperature higher than or equal to the transformation point. For example, in the case of Fe based alloy, a transformation phase formed by quench hardening from a solid solution state austenitic phase at a high temperature is designated. Thereby excellent magnetic and mechanical characteristics can be obtained.

Abstract: PURPOSE:To prevent the loss of an optical fiber and connector from entering as an error and to enable to perform a high-precise measurement, by a method wherein a pressure gauge employs a photo pressure sensor, which has transmissivity and reflecting rate changing with a pressure and a wavelength dependency, and consists of a two-wavelength system. CONSTITUTION:An emitting light having wavelengths lambda1 and lambda2 are combined together by a photo composing device 12, and is introduced to a photo pressure sensor 4 through an optical fiber 15 for entering. The sensor 4 converts an incident light into a parallel light by means of a micro lens 21, and after the light passes through a dichroic mirror 20 attached to a diaphragm 5, it is combined with an optical fiber 16 by a micro lens 22 to lead it to a photo electric converter 6. The electric signal of the converter 6 is converted into a DC signal by sample holding amplifiers 17 and 18 synchronizing with driver circuits 8 and 9, and is divided by a divider 19. The division removes an error produced due to a transmission loss and a connector loss, which results in being capable of performing a precise measurement.

Title: Control device for automatic stop/restart of engine
Inventor: INAGAWA SHINICHI
IPC: F02N15/00
Filed: 1984-01-31
Abstract: PURPOSE:To obtain a highly reliable device for automatic stoppage and restarting of an engine by utilizing a sensor detecting operational conditions of already equipped clutch and mission and confirming running of a vehicle and further deciding troubles of an engine rotation sensor and a car speed sensor. CONSTITUTION:After detecting operational conditions of a clutch and a mission and subsequently confirming traveling of a vehicle, a trouble of an engine rotation sensor is discriminated from that of a car speed sensor, and an alarm is given in case abnormality of the sensor is generated. Since automatic engine stoppage and restarting control are performed in case both engine speed and car speed are detected, there is not mistaking of surge pulse detection due to a noise for a car speed pulse regardless of a vehicle being in a state of stoppage. Further, since an alarm is generated when either the engine rotation sensor or the car speed sensor is in trouble, the sensor in trouble can be clarified to urge an operator to take some measure promptly. Furthermore, since automatic engine stoppage and restarting control is not performed in this case, safety is raised.

Filed: 1985-01-30
Abstract: PURPOSE:To correct errors to the best state by measuring an error detection rate instead of an error rate and executing the normal error correction if the error detection rate is lower than specified value and improving the error rate. CONSTITUTION:An error detecting means 11 detects the errors of input data and outputs error correcting data and error detection data. Error correcting data and input data which passes a delay means 14 are inputted to an error correcting means 12, and this means 12 selects whether error correction should be executed or not on the basis of error detection data which is the output of an error detection rate measuring means 13. The error detection rate measuring means 13 measures error detection data for a specified time to obtain the error detection rate, and the error correcting means 12 selects the execution or the non-execution of correction in accordance with output data. The delay means 14 delays input data to match the timing of input data to that of error correcting data.
