Title: Micrometer
Inventor: YAMAJI HIROSHI
IPC: G01B9/02
Filed: 1985-01-31
Abstract: PURPOSE:To enable the measurement of length with a high resolution, by mounting a first optical means on a box body to reflect laser light to a measuring element while a second optical means is mounted somewhere in the course thereof to form an interferring light to accomplish photoelectric conversion of the interferring light. CONSTITUTION:A laser light comprising two frequencies f1 and f2 are emitted in the direction of the arrow 8 from a laser oscillator 5. A part of the laser light is converted into a reference signal SR with the frequency f1-f2 with the first photoelectric detector 12. On the other hand, a part of the laser light as such with the frequency f2 only is shifted in the direction with a prism 18 to be emitted in the direction of the arrow 17. On the other hand, the laser light transmitted through a halfmirror 14 will be as such with the frequency f1 and converged with the laser light with the frequency f2 in the direction of the arrow 17 to be received with the second photoelectric detector 29. Then, when an object to be measured is removed from a base, the laser light with the frequency f1 in the direction of the arrow 24 changes in the frequency and a Doppler signal SD is outputted from the detector 29. Thus, after the counting of the signals SR and SD with counters 32 and 33, the counts signal SC1 and SC2 are outputted to a subtractor 34 to compute the difference there between.

Title: Electric cooking apparatus
Inventor: SHIMOMURA YOSHIRO
IPC: F24C7/04
Filed: 1989-01-26
Abstract: PURPOSE:To minimize the number of times of feeding and cutting off a current flowing to a lamp heater or the number of times of a great variation in a current value, and to prolong the life of the lamp heater by reducing the output from the lamp heater when a temperature detecting means for detecting the atmospheric temperature of the lamp heater detects a predetermined temperature or higher in and after a predetermined period of time. CONSTITUTION:In the title cooking apparatus, a temperature in a closed heating unit 2, namely, the atmospheric temperature of halogen lamps 3 is detected by a thermostat 8. Furthermore, in the case where the preset output from the lamps 3 exceeds 1.6KW, when the thermostat 8 detects a predetermined temperature to be turned OFF in and after a predetermined period of time, the output from the lamps 3 is programmed so as to be thereafter reduced to 1.6KW. Accordingly, when the thermostat 8 detects a predetermined temperature or higher in and after a predetermined period of time, the output from the lamps 3 is reduced and, thereafter, the heating rate of the lamps 3 approaches to the amount of heat which is absorbed into foodstuffs to be heated, whereby, for example, the period of feeding and cutting off a current flowing to the lamps 3 becomes longer.

Title: Electromagnetic connection apparatus
Inventor: KOBAYASHI RIYOUJI
IPC: F16D27/112
Filed: 1982-02-03
Abstract: PURPOSE:To increase the attractive force and at the same time reduce the dimension of the captioned apparatus by making the area of either or both of the friction surfaces at the center part smaller than that of the inside and the outside friction surfaces respectively. CONSTITUTION:When the area S of a friction surface, the magnetic-flux density Bg of the friction surface, and the permeability muo are set, an attractive force P is shown by the following equation: P=Bg<2>.S/muo, and the attractive force increases more when the magnetic-flux density Bg is increased rather than when the area S is increased. Therefore, on the friction surfaces 44 and 45, the attractive force is reduced, since the magnetic-flux density Bg is reduced by the influence of the leakage of magnetic-flux. Therefore, the magnetic-flux density Bg can be increased by reducing the areas of the friction surfaces 44 and 45 to about 60-80% of the friction surfaces 43 and 46 respectively, and the attractive force can be increased. Thus, the overall outside diameter can be reduced by reducing each area of the friction surfaces 44 and 45, and the dimension of the apparatus can be reduced.
