Title: Protecting device for endoscope
Inventor: CHIKAMA TOSHIO
IPC: G02B23/26
Filed: 1990-03-14
Abstract: PURPOSE:To prevent halation due to reflection light and breakage of a protecting tube by generating a height difference between the opened port part of an illumination light window and the opened port part of an observation window and forming a step difference part between the opened port surface of the illumination light window and the opened port surface of the observation window and forming the inner surface of the protecting tube along the step difference surface. CONSTITUTION:A part of the illumination light emitted from an illumination light window 14 is transmitted to an observation window 17 side through the repetitive reflection between the inner surface 25 of the bottom part 24 of a protecting tube 22 and the top edge surface 13 of a top edge constitution part 12. In this case, each of the inner surface 25 and the top edge surface 13 is not formed in a simple flat surface, but the top edge surface 13 is formed in a staircase form through the formation of a step difference surface 13c, and also the inner surface 25 is formed in a staircase form set along the top edge surface 13. Accordingly, the optical path length for the reflection light reaching the observation window 17 is made longer by the portion of the formation of the step difference surface 13c, in comparison with the case where each of the top edge surface 13 and the inner surface 25 is formed in a flat surface, and the reflection light is attenuated by the portion of the elongation of the optical path length during the advance of the reflection light through the repetition of reflection. Further, since the optical path light is large, there is no need of pressing the bottom part in its laid state to the projection part formed on the top edge surface of the top edge constitution part.

Title: Charcoal and its production
Inventor: NAMIKI HIDEO
IPC: C10L5/44
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain charcoal capable of avoiding disposal of hard tack, eliminating expense required for disposal and effectively utilizing hard tack whose shelf life passed and useful as portable fuel, activated carbon, graphite, or the like., by baking hard tack. SOLUTION: This charcoal is obtained by baking hard tack.

Title: Parity generating method
Inventor: KIKUCHI MIYOSHI
IPC: G06F11/10
Filed: 1983-04-08
Abstract: PURPOSE:To generate the integrated parity bit of a group of data by generating corresponding parity bits for every data received following to a clock by taking their previous record into consideration storing the generated parity bits in a register and collating the previous parity bit at every time. CONSTITUTION:This device is composed of a data outputting section 1 and parity generating section 2 and a data controlling circuit 12 sends a data sending start signal ST by one clock. A data outputting circuit 11 sends four-bit data. Therefore, the exclusive OR signal of the four-bit data inputted into a parity generating circuit 21 is obtained and a data parity signal DPG is outputted at each time. Since the output OGC of a register 22 is ''0'' at the 1st time, the signal DPG is stored in the register 22 as an output integrated parity signal PG as it is. On and after the 2nd time, a new parity signal PG is generated by taking the exclusive OR of the previous parity signal PGC and the parity signal DPG of that time.

Title: Synchronized operation control system for brushless motor
Inventor: HASHIMOTO HIROYOSHI
IPC: H02P5/52
Filed: 1979-05-18
Abstract: PURPOSE:To perform a synchronized operation with a simple and easy constitution by connecting a detecting device of each brushless motor to the detecting device of the remaining brushless motors so that the detected output of the former becomes the logical product of the corresponding detected output of the latter. CONSTITUTION:When the serial circuit of a resistance R1B and a detection element D1B is connected to both ends of a detection element D1A, the output of an intermediate connection point becomes ''1'' during the period of output ''1'' only by means of a detecting element D1B while output ''1'' is turned out by the detection element D1A. The continuity period of a feeding transistor Q1B is determined by the phase difference between rotors R0A and R0B. Thus the supply capability is controlled and the rotary phase of a motor B is synchronized to the rotary phase of a motor A.

Title: Scanning data storage system, its stylus and medium abrasion managing methods and remaining life display device
Inventor: SAITOU MITSUCHIKA
IPC: G11B27/36
Filed: 1996-02-23
Abstract: PROBLEM TO BE SOLVED: To extend the life of a device by exchanging data in a storage area in accordance with the frequency of access operation and storing an exchanged physical address correspondingly to a logical address corresponding to an unexchanged physical address of the storage area. SOLUTION: Access operation to reading/writing of data from/in a storage area formed on the surface of a storing medium is executed in each prescribed stylus group 31. A processor 43 exchanges the data of a storage area assigned to a stylus group having many access operation frequency counted by a counter 41 and the data of a storage area assigned to a stylus group having small access operation frequency. At the time of exchanging data, the processor 43 stores an exchanged physical address of a storage area in an address exchange table memory 42 correspondingly to a logical address corresponding to an unexchanged physical address of the storage area. Consequently the device life due to the limitation of access operation frequency of a stylus and the limitation of accessed operation frequency of a storage area can be effectively extended.

Title: Traverse guide of yarn take-up machine
Inventor: SUGIOKA TAKAMI
IPC: D01H13/06
Filed: 1987-03-16
Abstract: PURPOSE:To prevent the occurrence of fluffs and loops due to squeezes by slanting a yarn introducing surface on the front end of a traverse guide in the proceeding direction of yarn. CONSTITUTION:When a yarn Y is traversed by a traverse guide 2, a force F works by the tension of yarn Y, while a yarn introducing surface 2a at the front end of the guide 2 is slanted a slant angle theta in the proceeding direction so that the component F1 of the force works toward the front end of guide 2. And as the guide 2 is moved from the center portion of traverse to the end, the force F is increased and the components F1, F2 thereof are increased. Thus, the yarn Y begins to move along a groove 1 in the guide 2 toward the front end to produce a rotational force on a single yarn of yarn Y in the direction a so that the single yarn is moved in the direction b and arranged in the groove 1 approximately in a row. As a result each single yarn will uniformly share the tension without giving strong squeezes to only specified single yarns to prevent the occurrence of fluffs and loops.

IPC: G06F17/50
Filed: 1991-03-05
Abstract: PURPOSE: To simulate all possible states (i.e., all possible combinations of pointers, buffers, etc.) of a model in a short time. CONSTITUTION: Conversion from a high level to a low level is constituted in the form of formal top-down development procedure based upon successive improvement. Staring with the high level (abstract) such as the formal abstraction, etc., of a standard protocol, successive improvement is done to generate a detailed model. The said improvement is performed so as to guarantee the establishment of properties, confirmed at a certain level of the abstraction, at all subsequent abstraction levels. The successive improvement ends at a low-level 'model' forming the final implementation of the protocol. On the basis of formal verification, implementation by the finite state machine of a control-oriented system is automatically performed in a short time.
