Title: Controller for water pump of engine
Inventor: MORITA YASUYUKI
IPC: F01P7/16
Filed: 1981-03-27
Abstract: PURPOSE:To shorten the time of warming-up, by enabling the drive of a water pump independently of the rotation of an engine and by gradually increasing the rotational frequency of the pump to a prescribed high value when the temperature of the engine has become a set level or exceeded it. CONSTITUTION:A water pump 7 is installed in a cooling water passage 2 extending through a water jacket provided in the cylinder block 4 and cylinder head 5 of an engine 1. The pump 7 is driven with a belt 10 by an electric motor 11, the drive of which is regulated by a controller 9 on the basis of the output of a temperature sensor 12 which detects the temperature of the engine 1. When the temperature of the engine is not higher than a set level T1, the electric motor 11 is controlled to keep the pump 7 at prescribed low rotational frequency. When the temperature of the engine has become the set level T1 or exceeded it, the motor 11 is controlled to gradually increase the rotational frequency of the pump 7 to a high value. According to this constitution, the engine 1 is prevented from being excessively cooled when its temperature is low.

Title: Split connector
Inventor: FUKAMACHI MAKOTO
IPC: H01R13/518
Filed: 1997-02-28
Abstract: PROBLEM TO BE SOLVED: To reduce maximum pulling force acting on a lever. SOLUTION: Three subconnectors 11 are connected to each other, thus constituting a connector body 10, by which a lever 20 is turnably supported. Cam grooves 25, 26, 27 are formed at opposite faces in the lever 20 with the subconnectors 11 held therebetween. A female connector F can be pulled into the subconnector 11 by a cam action. The cam grooves 25, 26, 27 are different in shapes from each other, and therefore, the cam effect becomes maximum at different positions. Consequently, pulling force acting on the female connector F reaches its peak at positions deviated from each other, thus reducing the maximum pulling force acting on the lever 20.

Title: Speech synthesizing device
Inventor: OKUNO YOSHIMICHI
IPC: G10L13/00
Filed: 1988-02-29
Abstract: PURPOSE:To obtain a smooth voice by sectioning the generation time of respective phonemes into plural time zones by the phonemes constituting a syllable, specifying phoneme parameters of the sectional area, etc., of an acoustic tube by time zones and interpolating the phoneme parameters while performing interpolation processing according to a specific recurrence formula, specially, as to pitch. CONSTITUTION:The voice channel of a human is regarded as an acoustic tube group and made to correspond to a circuit element group of surge impedance components, thereby simulating a voice based on the current wave at the output terminal of a circuit element group. The interpolation arithmetic of an exponential function is not performed and the recurrence formula shown by an equation I extracted from the function is used to find respective interpolation values, so the arithmetic processing is easy. Here, an initial value is denoted as X(O), the initial value of a next time zone as Xr, an (n)th interpolation arithmetic value as X(n), and time constants corresponding to respective parameters as D. Consequently, a constant is selected to realize a slow pattern as to the interpolation processing of pitch, so a smooth voice is obtained and a listener is given a natural feeling.

Consequently, the light source need not be arranged in the encoder part 3, which can be made compact. Further, the stable light source 1 is arranged outside the encoder part 3 and used to improve environmental resistance and take a measurement with high accuracy.
