Title: Kick tester
Inventor: FUJITA KAZUYOSHI
IPC: H01F38/28
Filed: 1996-06-26
Abstract: PROBLEM TO BE SOLVED: To perform GO/NO GO test correctly by one worker without removing the secondary wiring of an instrument voltage or current transformer. SOLUTION: A worker connects a DC current generator comprising a dry cell 14 and a switch 15 across a part K-L where a CT 13 for R phase is provided such that the K side of the main circuit on the primary of the CT 13 comes on the plus side. A secondary DC current is induced at a local part of the R phase provided with the CT 13 by turning the switch 15 on/off. A clamp type current detector 2 for R phase delivers a pulsating signal to the control circuit 17 in a body 1 only when the induced secondary DC current has positive polarity. Upon receiving the pulsating signal, the control circuit 17 delivers an indication command and an alarm command, respectively, to an indication circuit 18 and an alarm circuit 19.  Consequently, an R phase indication lamp is lighted in red and an alarm delivers an alarm sound of predetermined tone thus notifying the worker that the secondary wiring of the CT 13 for R phase is correct.

Abstract: PROBLEM TO BE SOLVED: To maintain a satisfactory condition of chip parting by forming a chip guide face by a plurality of divided chip guide faces bent protrusively on a blade chamber side or a projecting circular arc face or a combination of these. SOLUTION: Chip slides on a surface of a second cutting face 3b, flows out along a first chip guide face 3f, and is curled at a radius of curvature approximate to a radius of curvature of a virtual cylinder 3d inscribed on the second cutting face 3b and the first chip guide face 3f. While chip is short, this curling continues, but a radius of curvature of curl increases as a length of chip increases. As a size of curl increases, the contact with chip is smoothly shifted from the first chip guide face 3f to a second chip guide face 3i so that the chip flows out stably along a plane of the second chip guide face 3i and is curled. This flow-out continues, and the chip is curled into a small and compact manner in a blade chamber 5 without coming into contact with a blade bottom 5a hard.

Abstract: PURPOSE:To adjust the position of movement to the rotational phase of a screw, and to simplify a feed mechanism by composing the feed mechanism moving a magnetic head to a desired recording track of the lead screws having a large number of threads of grooves and selecting the groove by a magnetic-head holding member. CONSTITUTION:A lead screw 11 is formed by a plastic mold, and a groove 13 in the same depth as a previously held groove 12 is shaped between the lead screw 11 and the groove 12. Consequently, the position of a carriage 4 can be changed over to the rotational phase of a stepping motor 5 only by shifting a needle 8 to the previously held groove 12 to the adjacent groove 13 in a feed mechanism 10. That is, the same effect as an effect, by which the whole motor 5 is turned and the position of mounting is adjusted, is acquired. Not only two threads but also multithreads such as triple, quadruple, etc., may be employed as required in the groove formed to the screw at that time.

Abstract: PURPOSE:To attain the high speed processing with the above system and device by securing the correspondence between a logical page of a basic page size and a single physical page and between an integer-fold logical page of a basic page size and an integer piece of physical pages. CONSTITUTION:An application program 21 includes a virtual memory space (virtual program space) 26 which is divided into pages of 4K-byte sizes and a virtual memory space (virtual file space) 27 divided into pages of 16K-byte sizes respectively. An access is given to the space 27 with an input/output instruction, and the accesses are applied to the space 26 with instructions except the input/output instruction. In this case, the page size of the space 27 is set at an integer-fold value as large as the page size of the space 26 and also at the value near the track size of a disk device 8.

Title: Video signal processor
Inventor: MATSUGAMI HISAKI
IPC: H04N9/64
Filed: 1995-06-30
Abstract: PURPOSE: To eliminate the disturbance component caused by the residual dispersal out of the luminance signal that undergone the Y/C separation. CONSTITUTION: The output of a Y/C separation circuit 12 is given to a BPF 16 and a horizontal high band component is extracted. A waveform shaping circuit 17 outputs a low level component of the output of the BPF 16 through the waveform shaping processing after deciding that the low level component of the horizontal high band component is equal to a disturbance component caused by the residual dispersal. A subtracter 18 subtracts the output of the circuit 17 from the output luminance signal of the circuit 12 and therefore eliminates the disturbance component due to the residual dispersal out of the luminance signal to send it to a selector 19. When a frequency detection circuit 15 detects a component of 15Hz, the selector 19 selects the output of the subtracter 18. Then the selector 19 outputs the output of the circuit 12 as it is when the component of 15Hz is not detected.

Abstract: PURPOSE:To eliminate the need of a document inversion mechanism, and to simplify a structure by reserving the feed of a copying form without copying the reverse side, when white paper of the reverse side of a document is detected by a data from a photoelectric conversion exposure system, replacing the document with the next document, and copying it to said copying form. CONSTITUTION:At the time of bringing successively plural sheets of documents to both-sided copying, if it is detected that the reverse side of the document is white paper, by a data from photoelectric conversion exposure systems 9, 13, a copying form is brought to holding at a prescribed part without executing the copying of this reverse side, and the feed of this copying form is reserved. On the other hand, the document whose reverse side is white paper is replaced with the next document, so that the next document is copied on the copying form whose feed has been reserved. Accordingly, the surface of the document, and the reverse side of the document are exposed by an optical exposure system 10, and the photoelectric conversion exposure systems 9, 13, respectively, therefore, both-sided copying can be executed without inverting the document. In such a way, the structure can be simplified by a portion which is not provided with a document inversion mechanism.

IPC: G02B5/30
Filed: 1991-07-08
Abstract: PURPOSE:To improve the utilization efficiency of light when polarizing light emitted by a light source into linear polarized wave. CONSTITUTION:The light which is emitted by the light source 11 and made into parallel light L11 by a parabolic surface 13 is split by a polarization beam splitter 17 into a P and an S wave which are linear polarized waves.

Consequently, the linear polarized S wave which is normally discarded can be utilized as the P wave. The utilization efficiency of the parallel light L11 emitted by the light source 11 is therefore relatively improved.
