Title: Time division multiplex communication method
Inventor: TAKANASHI HITOSHI
IPC: H04B7/24
Filed: 1994-01-25
Abstract: PURPOSE:To effectively utilize a frequency even if an interference exists by performing communication by shifting a timing frame where no interference exists according to the decision result of the interference location of a burst. CONSTITUTION:Before a transmission, the location of an interference wave as the difference of the reception frame pulse from a reception frame pulse generator 1 and the phase of an interference wave reception signal is detected 2, the result is integrated as necessary 3, and the integration result is transmitted to a transmission frame pulse generator 4. In the generator 4, the phase difference of the frame timing of the received interference wave and the frame timing of a station in use is detected. When an interference is detected in the first half part of the frame of the station in use, the self frame phase is delayed according to a phase difference and the phase difference with the interference wave is controlled so as to be the (n) (n is natural number) times as long as the time length of the frame. When the interference is detected in the latter half part of the frame of the station in use, the self frame phase is advanced according to the phase difference and the phase difference with the interference wave is controlled so as to be the (n) times as long as the time length of the frame.

Title: Automatic follow-up machanism for load limiter
Inventor: KIKUCHI KANJI
IPC: F01D15/10
Filed: 1979-02-28
Abstract: PURPOSE:To always suppress a sudden change in an actual output from a generator to not more than a predetermined level irrespective of the characteristics of a steam regulator valve, by controlling a load limiter with a differential signal which is obtained by subtracting from a set excess value the difference between a detection signal representative of the position of a speed governor and a signal representative of an actual output from a generator. CONSTITUTION:The difference PE between a detection signal representative of the position of a speed governor 70, which is detected by a position detector 80d, and a signal representative of an actual output from a generator 40, which is detected by an actual output detector 80e, is calculated by an adder 80f. An adder 80b is adapted to subtract the difference PE from an excess value VS set by an excess value setter 80a, and apply to a controller 80c the difference between the remainer obtained by this subtraction and difference between outputs from a load limiter 60 and speed governor 70. The position of the load limiter 60 is thus controlled.

Title: Manufacture of center electrode of spark plug
Inventor: ANDO MINORU
IPC: B23K26/21
Filed: 1992-01-14
Abstract: PURPOSE:To provide a center electrode excellent in heat radiation and further prevented from damage by stress deformation by preventing a cavity from its generation between a core member and an external member in the case of extrusion-molding the center electrode, in manufacture of the center electrode of a spark plug having a compound structure of comprising the core member and the external member. CONSTITUTION:By setting a top angle theta in the point end of a cone-shaped core member 14 and in the bottom of a hole part of the same-shaped external member 15 to a relation where 80 deg.<=theta<=120 deg. a cavity is prevented from being generated between the core member 14 and the external member 15 even in extrusion-molding a center electrode. Since a diameter of the core member 14 in the point end of the center electrode can be decreased, the core member of internally sealed high heat conductive material can be placed to approach the point end of the center electrode without decreasing also strength, and heat radiation can be improved.

Title: Ignition-timing controller for internal-combustion engine
Inventor: HARADA OSAMU
IPC: F02P5/153
Filed: 1985-02-12
Abstract: PURPOSE:To suppress knocking exceedingly effectively by installing an ignition- timing control means for controlling the ignition timing of an internal-combustion engine towards delayed angle or advanced angle and an ignition-timing delaying means which controls the ignition timing to the delayed angle side. CONSTITUTION:An ignition-timing control means B controls the ignition timing of an internal-combustion engine toward delayed angle or advanced angle by the signal supplied from a knocking detecting means A. An ignition-timing delaying means E is driven by the signal supplied from a sharp acceleration detecting means C and a high-load and high-revolution detecting means D and controls the ignition timing to the delayed-angle side independently of the signal supplied from the knocking detecting means A. Thus, knocking can be suppressed exceedingly effectively.

When the surface to be measured 13 is vertical with respect to the light axis, the beam spots are projected on the centers of the light detectors 15 and 16. With the inclination of the surface to be measured 13, the beam spots are projected on the positions deviated from the centers of the light detectors 15 and 16. The photoelectric output from each element of the light detectors 15 and 16 is operated, and the deviation of the beam spot from the center is corrected and the amount of defocus is computed. Thus the amount of minute displacement of the surface to be measured in the direction of the light axis is obtained.
