Title: V-type engine
Inventor: MATSUMORI YOSHIRO
IPC: F01L3/12
Filed: 1986-02-05
Abstract: PURPOSE:To cool an exhaust valve and an exhaust port so favorably as well as to improve the extent of coolability in a cylinder head, by installing a suction valve of each combustion chamber in the outward of each band, while installing an exhaust valve of each combustion chamber in the inward of each bank, in case of a narrow-angled V-type engine. CONSTITUTION:Since an exhaust valve 10 of each combustion chamber 5 is installed in the inward of each of banks R and L, the exhaust valve 10 and an exhaust port 8 are situated in the central part of a cylinder head 2 from the standpoint of a layout. That is to say, a lot of cooling water passages 6 small in bending parts are installed whereby they are situated in parts where cooling water is abundant and flows smoothly, thus the exhaust valve 10 the exhaust port 8 are favorably cooled by this cooling water. Therefore, coolability is improved and a temperature rise is checked, and consequently temperature distribution in the cylinder head 2 becomes equalized.

Inventor: SUMI HIROBUMI
IPC: H02K23/66
Filed: 1993-01-19
Abstract: PURPOSE:To reduce the size of a miniature motor by constituting the driving coil of the motor of bar-shaped coils arranged in parallel on the upper and lower surfaces of the rotor of the motor and contact coil sections in which one ends of the coils are connected to the upper and lower surfaces of the rotor. CONSTITUTION:The driving coil 4 of the motor is composed of bar-shaped coil sections 5 and contact coil sections 6 and the sections 5 are arranged in parallel on the upper and lower surfaces of a rotor 3. The contact coil sections 6 are wound around the rotor 3 while one ends of the coils sections 5 formed on the upper and lower surfaces of the rotor 3 and connected to the upper and lower surfaces of the rotor 3. Since an induced current flows to a supporting shaft 2 when the rotor 3 rotates, the rotor 3 can be continuously rotated in the same direction by detecting the induced current through the shaft 2 and discriminating the magnitude and polarity of the current with a microcomputer, and then, controlling the flowing direction of the current to the coil 4. Therefore, the size and driving energy of the miniature motor can be reduced.

IPC: G06K9/62
Filed: 1989-02-03
Abstract: PURPOSE:To shorten the recognition time of a following typed character by calculating an average similarity degree at every dictionary of respective fonts from a recognition category and a similarity degree outputted from a recognizing means for the kind of the font in an original picture and using the dictionary of the font with the higher average similarity degree. CONSTITUTION:A whole control means 9 stores the recognition dictionary of the second font, which is stored to a low speed access storing means 7 in advance, to a high speed access storing means 7 and the average similarity degree in the recognition dictionary of the second font is obtained and stored to the buffer of the means 9 itself. Next, the whole control means 9 compares the obtained average similarity degree with the average similarity degree when the recognition dictionary is collated with the recognition dictionaries of the respective fonts. Then, the recognition dictionary of the font with the higher average similarity degree is stored from the low access storing means 6 to the high speed access storing means 7. After that, the whole control means 9 determines the font of the recognition dictionary and outputs the recognition category collated with the recognition dictionary. Thus, the following type character can be recognized at high speed.

Filed: 1991-02-19
Abstract: PURPOSE:To transmit high-quality data by automatically switching an encoding rate corresponding to the frequency of using a terminal, increasing the encoding rate when there is scope in a processing, and decreasing the encoding rate when there is noscope. CONSTITUTION:For a voice signal from a voice terminal 10, the encoding rate is inputted to a coder 140 of 32kbps and an encoder 142 of 24kbps, and a selector 200 selects any one of outputs from the two kinds of encoders and inputs it to a cellcellulating part 162.

Title: Module for optical communication
Inventor: OKOCHI KEN
IPC: H01L31/0232
Filed: 1994-01-26
Abstract: PURPOSE:To prevent light from being reflected by an optical fiber end surface and to improve the positioning precision of the optical fiber end surface when a ferrule is mounted on the module for optical communication. CONSTITUTION:The outer peripheral part of a transparent film 25 subjected to a reflection preventing process is held in the groove 14d of a stopper member 14, and the film outer peripheral part is pressed against the inner peripheral surface of an elastic sleeve 23. Once the ferrule 4 is mounted on the elastic sleeve 23, the transparent film 25 comes into secure contact with the optical fiber tip surface 5a and ferrule tip surface 4a. No air layer is formed between the optical fiber tip surface 5a and transparent film 25 and laser light B is never reflected to the optical fiber tip surface 5a. The ferrule tip surface 4a is brought into contact with a positioning circuit 14b across the transparent film 25 to position the ferrule 4, and the image formation point (f) matches the optical fiber tip surface 5a in this positioning state. The incident precision of light to the optical fiber 5 is therefore made very high.

Abstract: PROBLEM TO BE SOLVED: To prevent loaded bulk cargoes from collapsing in case of an emergency operation stop by bringing/separating a belt pressing member, which touches the belt width center part, close to/from a belt face along the width direction of the belt by means of an action of an actuator. SOLUTION: A driving source 20 such as a hydraulic pump is connected to an actuator 16 so as to expand/shrink the actuator 16 by the pressure fluid. A controller 21 is connected to the driving source 21 so as to control the driving source 21 on the basis of the control signal. During cargo handling work, if meandering of a belt or the like causes an emergency stop condition, for example, the controller 21 gives a command to the driving source 20 to bring a belt pressing member 11 into contact with the belt 1, and controls the driving source 20. Whether the belt conveyor is operated normally or stopped in an emergency is inputted to the controller 21 by means of a stop signal and the like from the belt driving device. As a result, supporting force for conveying bulk cargoes put between the belts can be increased.
