IPC: G06F3/01
Filed: 1981-10-06
Abstract: PURPOSE:To improve the working efficiency of phrase input in a phrase input system to be used for ''kanji'' (Chinese character) input device by designating the leading character of a phrase and displaying characters continuous to the leading character on a character board through light. CONSTITUTION:At the input of a phrase, the leading character of the phrase is designated by a light pen or the like on a character board 10 in a ''kanji'' input device to display each character by transmitting light through each character surface on the character board 10. Subsequently a ''kanji'' code converting part 2 converts the designated character into a hexadecimal code, checks and detects the contents of a phrase dictionary 5 and outputs characters continuous to the leading character to a priority discriminating part 3. The characters continuous  to the leading character and outputted from the discriminating part 3 are displayed by transmitting light on each character surface on the character board  through a light emission driving part 4. Consequently the phrase is inputted and  its phrase using frequency is stored in a file 6.

Title: Temperature compensating circuit
Inventor: TAKAHAMA TEIZOU
IPC: G01R15/00
Filed: 1979-12-12
Abstract: PURPOSE: To compensate the inclination and bend of zero-point temperature characteristic by a method wherein the output of a resistance bridge generating temperature-dependent output is inputted to an operational amplifier for which either an input resistance or a feedback resistance is made to have nonlinear resistance temperature characteristic.  
     CONSTITUTION: A resistance having a positive or negative resistance temperature coefficient is used for one of the bridges R 3 WR 6  for compensation and thereby a signal compensating the inclination of the output of strain gages r 1 Wr 4  due to temperature is obtained. Moreover, by using a resistance having a resistance temperature coefficient which has a rise downward as the input resistance R 7  of the operational amplifier OP 1  or by using a resistance having the resistance temperature coefficient which has a rise upward as the feedback resistance R 8 , a signal compensating such characteristic of the output V in  of the strain gages r 1 Wr 4  that it shows the rise upward due to temperature is obtained. And, the compensating signal of the operational amplifier OP 1  is added to the output V in  of the strain gages r 1 Wr 4  in an operational amplifier OP 2  and thus an output V o  compensated for temperature is obtained.

Title: Wrap film case
Inventor: TASAKA FUMIO
IPC: B65D5/72
Filed: 1993-06-03
Abstract: PURPOSE:To prevent a lid body from rising from a case body after cutting off film with a cutting edge by a method wherein a folding angle between the bottom board and front side board of the case body is made larger than that between the upper side covering board and front side covering board of the lid body. CONSTITUTION:The folding angle alpha between the bottom board 6 and front side board 5 of a case body 1 is set at an angle of 92-100 deg. and the sloping side is formed outwardly of the case body 1. The folding angle gamma between the upper side covering board 12 and front side covering board 13 of a lid body 2 is set at an angle of 80-88 deg. and the sloping side is formed inwardly of the case body 1. Therefore, when wrap film 4 is pulled out from the case body 1 to be cut off by a slit 15, a portion of the front side covering board 13 of the lid body 2 is caught by a portion of the front side board 5 of the case body 1 to prevent the rise of the lid body 2 when the lid body 2 attempts to rise due to the restoring force of a crease ridge line 19 of the case body 1. If the folding angle between the bottom board 6 and front side board 5 of the case body is at most 91 deg., the lid rise preventing force is small and, if it is at least 101 deg., the container cannot be used practically. The folding angle between the upper side covering board and front side covering board of the lid body is the same.

IPC: H04N1/04
Filed: 1988-06-28
Abstract: PURPOSE:To constitute a stable feedback loop by scanning a CCD reference white plate even in the standby and applying the automatic level adjustment in a signal system reading an actual original. CONSTITUTION:As a pre-operation to read an original, a CCD image sensor 3 reads a reference white plate 2. This signal is compared with a voltage of a reference voltage generating circuit 21 by a comparator circuit 22. The output of the circuit 22 is connected to a lighting circuit 24 via a relay 25 and the output of the circuit 24 is connected to a fluorescent light 1. The circuit 22 is operated to increase the luminous quantity of the fluorescent light 1 when the output voltage of the sensor 3 is lower than the reference voltage and to decrease the luminous quantity of the fluorescent light 1 when the output voltage is higher than the reference voltage conversely. In the case of reading an actual original, the relay 25 is thrown to the position of (b) and the input voltage of the circuit 24 is fixed to the voltage just before by the voltage holding circuit 23 to keep the luminous quantity of the fluorescent light 1 constant.

IPC: H03F1/30
Filed: 1989-06-22
Abstract: PURPOSE:To obtain a power amplifier with excellent power efficiency and less crossover distortion by forming a resistive element formed to one terminal of a transistor(TR) for constant voltage bias circuit and an output power TR on one and same substrate. CONSTITUTION:A composite power TR semiconductor element is arranged, in which a resistive element 17 and an output power TR 10 formed at one terminal of a TR 4 for a constant voltage bias circuit are formed on one and the same section substrate 18. When the output power TR 10 is heated, the heat is momentarily delivered to the resistor 17, a bias voltage formed by constant voltage bias circuits 4, 5, 17 is changed to compensate the bias voltage of the output stage. Thus, since a temperature stability is attained even with a sufficiently smaller emitter resistance, the power amplifier with excellent power efficiency and less crossover distortion is attained.

Abstract: PURPOSE:To make a glass tube formable into U-shaped type without fail, by guiding the revolution of a chuck around a main shaft with a first cam, while controlling the rotation of the chuck with a second cam. CONSTITUTION:When turning frames 4a and 4b are turned round in each direction of arrows A and B, each of first cam rollers 25a and 25b attached to turning shafts 15a and 15b roll in contact along cam surface 30a and 30b of a first cam 28 so that a chuck on the turning shaft also shifts its locus along these cam surfaces 30a and 30b and is revolved around a main shaft 3. Each of second cam rollers 27a and 27b is shifted as rolled in contact with cam surfaces 32a and 32b of a second cam 29. Therefore, these turning shafts 15a and 15b are rotated in following these cam surfaces 32a and 32b of the second cam 29. Accordingly, the chuck also rotates and makes a nipping part of the glass tube direct toward the main shaft 3 all the time, thus a straight line part continuing to a U-shaped part is secured.
