Title: Magnetic tape controller
Inventor: HIRABAYASHI NAOKI
IPC: G11B20/18
Filed: 1996-04-03
Abstract: PROBLEM TO BE SOLVED: To write in data without retraining by detecting positional deviation with a reference position from a gap start position signal and calculating a corrective direction and a corrected value. SOLUTION: A read element 1 of a magnetic head 3 is on the last part of a (n-1)-th data block, and a write-in element 2 is on an n-th data block. At this time, when the data are written in from the n-th data block, the matter that a magnetic tape is made a prescribed speed is required. Then, the magnetic head 3 is accelerated in the opposite B direction to be moved at a fixed speed after it is returned by a gap G required for obtaining a prescribed speed in the A direction. When the write-in element 2 comes to a gap start position, a magnetic tape device informs a magnetic tape controller of a gap start position signal. At the time, when the gap start position signal is advance or delayed from the reference position, that is detected, and the correction value is calculated to be sent to the magnetic tape device.  Thus, the write-in becomes possible by calculating the corrective direction and value without the retrying.

Title: Wiping cloth
Inventor: SHIMAMOTO KAORI
IPC: D03D15/567
Filed: 1991-03-20
Abstract: PURPOSE:To improve wiping performance, water absorbency, color forming property and fashionability by using conjugate yarn of textured yarn with a specified single fiber fineness and multifilament yarn with a boiling shrinkage larger by a specified ratio than the textured yarn at least for warp and further imparting a specified average specific capacity to the cloth. CONSTITUTION:Fiber used for the surface of a pile-like woven fabric of wiping cloth must meet the requirement of 0.5 denier or less in the single fiber fineness. When the single fiber fineness exceeds 0.5 denier, the wiping capacity is worsened. Then, the textured yarn with the fine single fiber fineness is conjugated with multifilament yarn having a boiling shrinkage exceeding 10% as compared with the textured yarn. When difference of the boiling shrinkage is below 10%, the development of piles becomes insufficient. The constituent fibers of the conjugate yarn may be the same or different in type. Moreover, the pile-like woven fabric exceeds 5cm<3>/g in average specific capacity. Even with the actual value less than the value, there is no extreme lowering of the wiping capacity of the cloth but the storing capacity of dirt and water/oil absorbing performance becomes worse.

Title: Light wavelength measuring instrument
Inventor: TAMURA YOICHI
IPC: G01J3/453
Filed: 1990-03-29
Abstract: PURPOSE:To improve the measurement accuracy without increasing the size of the instrument by counting the fraction values of respective repetitive waveforms of reference light and light subjected to photometry which overlap each other at the start and end of the counting of the number of repetitive waveforms of a light intensity signal by different counters. CONSTITUTION:Wave number counters 13 and 15 count the number of repetitive waveforms of the light intensity signal when a mobile mirror moves by a prescribed distance. Then the start fraction time from the start of counting by the wave number counters 13 and 15 to the 1st actual counting position arrival of the repetitive waveforms and the end fraction time from the end time to next counting position arrival are obtained by a fraction counter 22. Further, the period of the repetitive waveform is found by a period counter 23. Therefore, the ratio of each fraction time to a period, i.e. the number below the decimal to be added to or subtracted from the obtained repetitive waveform number is found. Consequently, the correct repetitive wave number including the decimal part can be calculated.

Title: Electron impact emission spectrodetector
Inventor: KIKUCHI TOSHIO
IPC: G01J3/443
Filed: 1997-03-14
Abstract: PROBLEM TO BE SOLVED: To improve detecting sensitivity for gas molecules or atoms by forming an anode electrode into a coil shape or a mesh shape, so that electrons can reciprocatingly run at the anode electrode. SOLUTION: When electrons are released from a thermoelectron releasing electrode 5 in the vacuum atmosphere, the electrons go to an anode electrode 19. Because the cylindrical anode electrode 19 is formed into a construction of coil shape or mesh shape spatially having gaps, the major part of the electrons are passed through the anode electrode 19. The passing electrons are returned in the direction of the anode electrode 19 of higher potential than a nipple 2 or a flange of ground potential. The electrons repeat such motion and reciprocatingly run, and the whole electrons are finally caught with the anode electrode 19.  By lengthening the running distance of the electrons in this way, probability causing collision of the electrons with gas molecules 10 or the like is heightened, rate of the electrons colliding with the gas molecules or the like is increased, and hence partial pressure measuring sensitivity is improved.

Title: Automatic screw tightening machine
Inventor: YOMO OSAMU
IPC: B23P19/06
Filed: 1989-04-03
Abstract: PURPOSE:To correct the reduction of the max. output torque due to the reduction of the traction coefficient due to the rise of the oil temperature by making an arm and a speed change ring from steel and making a driver body fro Invar having the less expansion coefficient than that of the arm and the ring. CONSTITUTION:When screw tightening work is repeated, and the temperature of the oil charge into a driver body 4 rises, the traction coefficient of the oil reduces, and the output torque reduces. Meanwhile, a speed change ring 14 and an arm 16 linearly expand over the driver body 4, accompanied with the rise of the oil temperature. Therefore, the speed change ring 14 shifts upwardly for an input disc 7, and the contact position with a planetary cone shifts to the high speed side. Through this shift, the tilt angle of the arm 16 increases. Further, the revolution torque generated on the speed ring at the time when the speed change ring 14 reaches the zero revolution position increases. Therefore, the output torque of the driver bit increases by the reduction portion of the max. output torque.

Abstract: PURPOSE: To aim at improving the operability and weight transportation capacity of a bag, by making the center point of a pair of rearmost wheels to be positioned closer than the center point of a pair of frontmost wheels to an intermediate point of an elongated structure. CONSTITUTION: This bag 20 comprises a plurality of wheels 22 and 24 attached to an elongated bottom structure or a bottom plate 26. The arrangement of these rear wheels 24 greatly improves the mobility of the bag 20. When moving, the bag 20 pivots about the center point P of the rear wheels 24. By moving forward the center point P of the rear wheels 24, the radius of gyration of the bag 20 is reduced, and by the reduction in the radius of gyration, as shown by an arrow 40, the bag 20 can rotate within a small area. Also, the arrangement of the rear wheels 24 gives an increased weight transportation capacity to a bag having soft sides. Namely, since the bottom plate 26 droops down less, the bottom plate 26 of a thinner or lighter structure can be used.
