Title: Engine with piston reciprocated by pressurized fluid
Inventor: YONEZAWA KEITAROU
IPC: F01L1/00
Filed: 1979-08-29
Abstract: PURPOSE: To heighten the efficiency and velocity of action of the piston of an engine reciprocated by a pressurized fluid, make an electricity generator compact and enhance its performance, by communicating the spring pressure backward movement chamber of the piston with a pressurized gas exhaust chamber.  
     CONSTITUTION: A piston 2 is moved forward by a pressurized fluid and moved backward by a spring 12 synchronously with a change-over valve 11. The spring pressure backward movement chamber 9 of the piston 2 is communicated with a pressurized fluid discharge chamber 17 through a communication hole 35 so that the fluid in the backward movement chamber 9 of decreasing volume is let to escape into the discharge chamber 17 of increasing volume through the communication hole 35 when the piston is moved forward and that the fluid in the discharge chamber 17 of decreasing volume is let to escape into the backward movement chamber 9 of increasing volume when the piston 2 is moved backward. This results in reducing back pressure on the piston 2 and a valve change-over member 25, heightening the efficiency and velocity of action of the piston, making an engine compact and enhancing its performance.

Title: Character recognizing device
Inventor: TOMONO KOUZOU
IPC: G06K9/62
Filed: 1981-07-16
Abstract: PURPOSE:To eliminate the effect of linking and separation of character lines and to recognize manuscript characters with high accuracy, by picking up straight line segments from an input pattern and recognizing the characters through the use of a middle point pattern depending on the length of the segments. CONSTITUTION:Inputted characters on a slip 6 are scanned with a scanning means 7 of a character recognizing device, and an input character pattern is made into fine lines with a pre-processing means 8. Strokes are picked up from the character pattern made thin with a stroke pickup means 9 and the picked up strokes are applied to a decision means 10. The means 10 obtains the stroke middle pattern depending on the length to obtain the similarity between the stroke middle pattern and the stroke middle pattern depending on the length of the standard character stored in advance and to determine the name of characters of input characters. The effect due to linking and separation of the character lines can be excluded and the recognition of manuscript characters can be made with high accuracy.

Title: Logic circuit device
Inventor: HAYAMIZU SADAHIRO
IPC: H03K19/088
Filed: 1986-05-13
Abstract: PURPOSE:To obtain a logic circuit device with high noise margin for both input/ output by adopting different kinds of metals for anode metals constituting an input SBD and a clamp SBD for an output SBDT so as to lower the forward voltage of the former and to increase the forward voltage of the latter. CONSTITUTION:An input Schottky barrier diode (SBD) 3 is constituted by a metal decreasing its forward voltage VF8, e.g., aluminum to input threshold value thereby improving the input noise margin. On the other hand, an 'L' value of an output voltage V11 is a collector-emitter voltage VOE7 of an output Schottky barrier diode transistor (SBDT) 7 and a difference between the base- emitter voltage V E7 and the forward voltage VF(B-O)7 of th clamp SBD inserted between the base and collector. Thus, the forward voltage VF(B-O)7 of the clamp SBD is formed to a comparatively large value close to the VBE7 by using a metal, e.g., platinum so as to lower the 'L' value of the output voltage V11 and to improve the output noise margin.

Title: Recording part of thermal transfer printer
Inventor: HASEGAWA ATSUO
IPC: B41J2/325
Filed: 1986-05-14
Abstract: PURPOSE:To obtain good printing, by making the pressure contact angle of a thermal head to a platen variable to make it possible to select a low speed mode wherein the thermal head is inclined to press only one row of heat generating element groups to a thermal ribbon, and a high speed mode wherein the head is made parallel to the platen to press two or more rows of the heat generating element groups to said thermal head. CONSTITUTION:In a high speed mode, a cam 6 is rotated by a rotary solenoid and a thermal head 3 rotates around a shaft 8 to become parallel to a platen 1. Head pressure necessary for thermal transfer is applied to a thermal head 3 and printing is performed by using the heat generating element groups 15 provided on both side edges thereof. In a low speed mode, the solenoid is not excited, and the thermal head 3 is inclined at a definite angle to the platen 1, and only the heat generating element group 15 provided to the edge on one side of the thermal head 3 presses a thermal ribbon 2 to perform printing. In the low speed mode, the high head pressure to the thermal ribbon 2 is obtained even by the same pressing force as in the high speed mode. Therefore, a good recording can be attained even on recording paper 4 of a low surface smoothness.

Title: Card collation system
Inventor: KAMAE NAOHIKO
IPC: G06Q40/00
Filed: 1982-06-30
Abstract: PURPOSE:To avoid an increment of invalid accounts and to reduce the effects of changes of secret numbers, by invalidating a card just with a change of the secret number along with the general number kept as it is. CONSTITUTION:A card 7 of a card collation system contains a general number part 8, a secret number part 9 and a recording part 10 of signs, etc. Such a card 7 is put into a card input device 1, and the general number and the secret number are read. This read information is applied to a card validity deciding device 3 using a computer, etc. via a communication network 2. Then the corresponding registered secret number is read out of a card file 4 in response to the general number. This read secret number is collated with the general number, and the validity is decided when coincidence is obtained. Then the desired data is transferred to a data processing center 6. When a reissue is requested for the card 7, the part 9 of the file 4 is changed by a secret number input device 5 with the part 8 of the card 7 kept as it is. This avoids an increment of invalid accounts and reduces the effects of changes of secret numbers.

Title: Data signal transmission method
Inventor: OKUMURA YUKIHIKO
IPC: H04B1/76
Filed: 1996-05-02
Abstract: PROBLEM TO BE SOLVED: To improve the quality in the case of data signal transmission. SOLUTION: Data signal are assigned between a 1st pilot signal PS1 and a 2nd pilot signal PS2 by a slot multiplexer circuit 15. When one slot period is 1msec and a transmission speed is less than 32kbps, burst transmission is conducted. In this case, the slot multiplexer circuit 15 assigns a data signal in the middle of each slot. For example, when the transmission speed is 16kbps or 8kbps, a data signal in 16-bit or 8-bit is assigned in the middle of each slot. In this case, even when a signal to noise ratio of the transmission line is low and the transmission quality is wrong, since noise superimposed on the 1st, 2nd pilot signals PS1, PS2 is averaged at the middle part of each slot, it is possible to conduct synchronization detection by using a highly accurate reference phase.
