Title: Tension stabilizer for wire saw
Inventor: MIYOSHI KOUTAROU
IPC: B24B27/06
Filed: 1997-12-01
Abstract: PROBLEM TO BE SOLVED: To set a circumference of a wire saw wrapped around groove rollers to be nearly identical in any parts irrespective of the length of a work by providing tension adjusting rollers brought into contact, among saw wires, a traveling saw wire in a range other than the contact range of the work to push the same. SOLUTION: Saw wires 4 wrapped around groove rollers 1 to 3 are brought into contact with a work 9 in a range A and with tension adjusting rollers 10B and 10C in the other ranges B and C and, since equal distortions are generated by these contacts, the tensions of the saw wires 4 are maintained equal in any parts. Thus, the circumferences of the saw wires 4 are equal in any parts. The cutting accuracy of the work 9 is expected to be nearly identical in both end parts and a center part. The lives of the groove rollers 1 to 3 are prolonged.

Title: Picture processor
Inventor: HARADA MASAHIKO
IPC: G09G5/377
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To execute a plotting processing by multiple clip at a high speed even when plural overlapped clip areas are set. SOLUTION: A multiple clip judging means 25 receives a clip command, and judges whether or not it is a multiple clip. When it is the first clip command, a clip area plotting means 15 plots the inside part of a clip area as '1' in a clip buffer 17, calculates a rectangular area circumscribing the clip area, and when it is the second and later clip command, the clip area plotting means 15 calculates a new rectangular area surrounding the previous clip area and this time clip area. A clip buffer access data controlling part 27 controls the clip area plotting means 15 so that '0' data can be written outside this time clip area inside the new rectangular area, and leaves a part in which the both areas are overlapped as a new clip area.

Inventor: NAKAYAMA TERUO
IPC: D01H1/115
Filed: 1993-12-20
Abstract: PURPOSE:To provide an air spinning device capable of producing a bound spun yarn high in the composing ratio of wound filaments and excellent in the strength of the yarn. CONSTITUTION:In the air spinning of a sliver, the sliver S is fed from a pair of the front rolls of a draft device in a flat press-spread state. The central filaments (fa) of the sliver S are collected by the false-twisting action imparted with the sucking and revolving flow of air into an auxiliary nozzle Na and simultaneously guided into the nozzle Na. Simultaneously, the tips of the filaments (fb) on both the sides of the sliver S are sucked into the outer peripheral filament bundle passage 3 of the auxiliary nozzle Na in a free state. When the tips reach a winding nozzle N1, the filaments (fb) are revolved in the direction opposite to the false-twisting direction and wound on the filaments (fa). In the subsequent process for untwisting the false-twisting of the core filament bundle comprising the collected filaments (fa) on the downstream side of a twisting nozzle N2, the wound filaments (fb) are further strongly wound to form a bound spun yarn Y.

Title: Frequency measuring circuit
Inventor: ISHIHARA HISAO
IPC: F02B75/02
Filed: 1991-12-26
Abstract: PURPOSE:To measure a frequency with high precision by prohibiting the cycle measurement operation in the execution of zero calibration. CONSTITUTION:Time lag exists up to the time when the reverse cycle signal *FIn becomes H from the ZERO CALL state of the control signal for switching a selecting switch SW to the zero calibration mode, and each timing of the cycle FIn of the ac input and of the ZERO CALL control signal is asynchronous. Accordingly, flip flops FF3 and FF4 are installed, and the starting-up of the Q output of FF3 is set in precedence by 1/2 cycle of the standard clock cycle Fclk from the starting-down of the reverse *Q output of FF4. In the execution of ZERO CALL, FF1-3 are cleared, and a counter gate is closed, and on the starting-up of *FIn after the completion of ZERO CALL, the Q output of FF1 becomes H, and a timer U3 is triggered. With this constitution, the frequency measurement with high presision is enabled without taking in the cycle data which is dropped in zero calibration.

IPC: B65G33/26
Filed: 1995-12-07
Abstract: PROBLEM TO BE SOLVED: To disperse the force added to a blade in the finishing of a trough and prevent a stress collection or distortion by dividing the scraping member on the peripheral part of the blade, mounting each piece on a plurality of peripheral edge parts of the blade, and rotating the blade within the trough to which a finishing material is supplied. SOLUTION: A scraping member 5a is installed extending from the start end (a) to the terminal end (b) of a blade 3a on the first line, a scraping member 5b is installed extending from the start end (c) to the terminal end (d) of a blade 3b on the second line, and a scraping member 5c is installed extending from the start end (e) to the terminal end (f) of a blade 3c on the third line. When the blade is supported within a trough 2, and a facing is supplied into the trough 2 followed by rotation, the scraping members 5a, 5b, 5c finish the trough inner surface. Since the scraping carrying force of the facing is allotted to each blade 3a, 3b, 3c, the stress collection can be prevented, the blade is never distorted in working, and a proper clearance can be ensured between the periphery of the blade and the trough inner surface.  In the attachment and detachment of the scraping members, the operation is facilitated, compared with a conventional long scraping member.

Filed: 1991-12-27
Abstract: PURPOSE:To enable an infant to learn addition and subtraction while playing by properly arranging and storing many different-length piece members based upon the minimum unit corresponding to a number of 1. CONSTITUTION:The 1st piece member 3a is a minimum unit member meaning the number 1, so this 1st piece member 3a is put in the 1st storage recessed part 2a of a base board 1 and then securely fixed by magnetic attraction. Then even when the 1st piece member 3a is put in the 2nd storage recessed part 3a, an empty part is obtained, so unless another 1st piece member 3a is put in, this 2nd storage recessed part 2b is not filled, so that the infant tries to find the 1st piece member 3a among many other piece members 3a. Thus, the piece member 3a which is the minimum unit corresponding to the number 1 and the storage recessed part 3a are used first and an adult while contacting the infant teaches a way of playing and then the infant naturally recognizes and understands the relation between the 2nd storage recessed part and 2nd piece member 3b, thereby exerting great influence upon the development of intellectual training.

Filed: 1992-12-25
Abstract: PURPOSE:To form a bipolar device and a MOS device on the same substrte by forming single crystal Si layers having the different thickness on an embedded SiO2 layer in an SiMOX process. CONSTITUTION:An SiO2 film 8 is formed so as to cover a part, where a single- crystal layer Si layer 4 is made thin, on an Si substrate 1, and patterning is performed. When oxygen ion in high concentration is implated, the oxygen is implanted at the part covered with the pattern film 8 to the shallow position. The oxygen is implanted to the deep position at the part, where the pattern film 8 is not present. Therefore, an embedded SiO2 layer 2 as an insulating layer and a damaged Si layer 3 become deeper than the part, where the pattern film 8 is present, at the part, where the pattern film 8 is not present. Furthermore, the single-crystal Si layer 4 can be thickly formed than the part, where the film 8 is present, at the part, where the pattern film 8 is not present. A gaseous-phase epitaxial Si layer 5 is deposited. After the Si layer is made thick, the single crystal Si layers 4a and 5 are patterned, and single crystal Si layers 6 and 7 having the different thicknesses are formed in the first and second regions on the embedded SiO2 layer 2.
