IPC: B41J27/10
Filed: 1980-11-19
Abstract: PURPOSE: To exactly print clear letters with high speeds by a method in which each time an ink supplyer part comes into contact with the types of a printing means, its contacting position is altered.  
     CONSTITUTION: Types 102 are printed on the bottom of a cap C being transferred intermittently, and then an arm 101 is turned in the direction of arrow D to separate a printer 100 from the cap C, where the types 102 are turned in the direction of arrow E. At the same time, the ink trap container 108 of an ink supply mechanism 106 is turned in the direction of arrow F, where a transfer roller 112 partially projected from a opening 113 does not rotate (Fig. a). Then, at the position as shown in Fig. b, the types 102 come into contact with the transfer roller 112, receive an ink there, rotate in the direction of arrow D for a while, and moves in a direction opposite to the direction of arrow D. On the other hand, the container 108 also rotates in a direction opposite to the direction of arrow F, but the transfer roller 112 rotates in the direction of arrows and renews its conacting poisition with the types 102 while receiving fresh ink from the ink supply part 111.

Title: Integrated circuit of semiconductors for clock
Inventor: MISAWA TOSHIYUKI
IPC: G01K7/24
Filed: 1978-12-28
Abstract: PURPOSE:To miniaturize a clock by using a Wheatstone bridge formed with integrated resistors of different temperature factors for the detection of temperatures. CONSTITUTION:The temperature factors of resistors R1, R2 which form a bridge are set to alpha(1/ deg.C), beta(1/ deg.C) to equalize the temperature factors of resistors R3, R4. The resistance value of the resistor R4 can be varied in order by the sweep of a counter. When the resistance vllue has exceeded R4/R3=R10(1+alphat)/R20(1+betat), (wherein R10, R20 have values equal to those of R1, R2 when t is zero), an output from a comparator C is changed from a high level to a low level. A value in the counter at this time is that of a signal representing a temperature. Thus, a temperature sensor portion and a logical gradient portion can be integrally circuited and provided in the same tip as an integral circuit for the clock. This allows a clock to be miniaturized.

Title: Step-out detecting circuit
Inventor: ODA SHIGETO
IPC: H02H3/48
Filed: 1991-06-07
Abstract: PURPOSE:To make a decision of step-out by communicating voltage information in single bit between the opposite ends thereby making a decision of voltage phase between the opposite ends of a transmission line. CONSTITUTION:On the opposite ends of a transmission line 1, voltage data provided from the transmission line 1 is sampled ever predetermined time at a converting section 31 and thus sampled data is fed to a positive/negative deciding section 36. A single bit data representing a positive or negative voltage data at the sampling time is fed to a step-out deciding section 37 and through a communicating section 4 to a step-out deciding section 37 on the opposite side. When the number of sampling time having unmatched single bit data increases, a decision is made that the transmission line has stepped out. Since only a single bit voltage information signal is required to be communicated between the opposite ends for making a decision of step-out, amount of data to be transmitted can be decreased.

Title: Box body structure of pocket television
Inventor: NAKAZAWA YOSHIO
IPC: H04N5/64
Filed: 1978-12-29
Abstract: PURPOSE: To make a pocket liquid crystal TV small-size and light-weight and improve stability, sensitivity and design by storing the antenna in the hood of a liquid crystal picture display equipment.  
     CONSTITUTION: Liquid crystal picture display equipment 5 is approximately 3mm thick and is very thin, and no parts of a fly-back transformer, etc., are required for this equipment because a high voltage power source is needless, and the power source part is small-size because power consumption is very small. Consequently, pocket TV 4 using this display equipment becomes small-size and light-weight. However, if the conventional rod antenna is equipped, stability in the use state is very bad. Since liquid crystal display equipment 5 is pressed and scratched, switching type hood 7 is essential. Therefore, antenna 6 is stored in hood 7 of liquid crystal picture display equipment 5. Thus, pocket liquid crystal TV 4 can be small- size and light-weight and be improved in stability, sensitivity and design.

Title: Address conversion buffer
Inventor: MORISUE HIDEO
IPC: G06F12/10
Filed: 1983-09-08
Abstract: PURPOSE:To adapt an address conversion buffer to a high-speed processor by increasing effectively a processing speed for partial erasion of a high-speed address converter in accordance with a certain condition. CONSTITUTION:A logic space number part 16 of a directory part is different from a logic page number part 17 and receives the same address as an upper effective display 15. An FF31 is usually set at ''0'', and the upper effective bit 15 is used in combination with other parts 16-18 of an RAM14. In case a counter 35 is negative and the FF31 is set at ''0'', the maximum value of the RAM address is set to the counter 35. At the same time, the FF31 is set. If both counter 35 and FF31 are not under the above-mentioned state, it means that a hidden TLB is not erased yet. Then the above-mentioned state is waited for. Thus the lower effective bit 30 is used.
