Title: Nmr measuring method of solid body
Inventor: TOIOKA KATSUYA
IPC: G01N24/12
Filed: 1989-09-07
Abstract: PURPOSE:To realize power matching only by an electric method and to prevent the reduction of S/N ratio by modulating the width of at least either of a spin locking pulse train or of a monitoring pulse train. CONSTITUTION:A solid sample is rotated at high speed with a magic angle in a detector 23. Outputs from oscillators 11, 12 of a radiating system and a monitoring system are projected on the detector 23 via a duplexer 22. After the emission of 90 deg. pulses, a spin locking pulse train is radiated and also a monitoring pulse train is radiated. A signal is detected through power matching of the pulse trains. At this time, the pulse width of at least one of the pulse trains is modulated within a monitoring pulse period to change the radiating high frequency power, thereby satisfying the power matching condition. As a result, a signal after cross polarization is detected and divided through the duplexer 22 to be received by a receiver 24, which is further processed by a data processing system 25 to monitor the spectrum.

Inventor: YOSHIDA KOJI
IPC: G02B6/38
Filed: 1984-11-06
Abstract: PURPOSE:To hold the mirror surface-like cut surface of a core with a plug without damaging the cut surface by rotating a rotary mechanism for holding a knife part and a thin plate part with an interval eccentrically from the center axis of a coupler. CONSTITUTION:An optical fiber core 1 exposing its strand part 2 is penetrated into a ferule part 11 of a simple type optical connector plug and fixed and the rotary disc 51 of which annular projection 52 is engaged with a groove 26 is rotated around an axis L2 by 180 deg.. Since the axis L2 is eccentric from the center axis L1, the flexible thin plate 40 and the knife part 30 are moved immediately under the strand 2 and immediately over the strand 2 respectively, the strand 2 is initially cut by the knife part 30 and then the strand 2 is bent together with the thin plate 40 to obtain a cut surface approximate to a mirror surface. Consequently, it is unnecessary to penetrate the cut strand into the ferule part and a cut surface approximate to a mirror surface can be always secured for the plug without damaging the cut surface.

Abstract: PURPOSE:To easily investigate the cause of abnormality by providing a control means for definitely displaying the abnormality and making it possible to confirm the point of time when the abnormality is caused in the case that the abnormality is caused during a preheating mode. CONSTITUTION:A display means 100 for concentratively displaying plural pieces of information related to copying is provided and the preheating mode for making a thermal fixation device in a state where the temperature thereof is made lower than a fixation-enabled temperature by a specified temperature is set.

Namely, if the abnormality occurs during the preheating mode which is set to save power consumption, only the abnormality can be displayed without releasing the preheating mode. Thus, the cause of troubles can be easily investigated.

Filed: 1986-09-30
Abstract: PURPOSE:To produce a uniform spread and flow of a molten resin, by allowing a relatively large resistance to act on the flow in a cavity gap corresponding to a place where a distance to the circumferencial part is short when a molten resin injected at a roughly central position of the rear face side spreads and flows in a circular shape along the rear face. CONSTITUTION:Resistances to flow of a molten resin are made different, in a cavity gap corresponding to positions 1a, 1a... where the distance l1 from the resin injection position of an in-flowing gate 12 to the circumferencial part of a main body of a molding 1 is short, and in a cavity gap corresponding to position 1b where the distance l1 is long, from each other and the difference in resistance to flow is made in such a way that it is larger at the positions 1a, 1a... where the distance l1 is shorter than at the position 1b where the distance l1 is long. The molten resin 2 covering over the rear face of the main body of the molding flows into a cavity gap 11d of the front face side almost simultaneously from the whole circumferencial side through a cavity gap 11c of the circumferencial side face, and gaps which may otherwise generate by catching air bubbles do not occur at the frame part of the bottom side which is visible from the outer surface.

Title: Cooling device for semiconductor element
Inventor: NAKAMOTO AKIRA
IPC: H01L31/024
Filed: 1983-12-10
Abstract: PURPOSE:To contrive the saving of power and the miniaturization of the titled device by a metod wherein a heat transfer member is installed to the lead terminal of a semiconductor element, and the heat-absorbing plane of a thermoelectric cooler is thermally connected to the heat transfer member. CONSTITUTION:The plus side lead 1b of an Si photodiode 1 is soldered to a brass terminal 11, and on the other hand the minus side lead 1c is inputted to a current-voltage conversion amplifier 6. The terminal 11 is joined to an Al block 12, which block 12 is then grounded electrically and thermally adhered to the heat- absorbing plane 13a of the thermoelectric cooler 13. Since the passage of constant current to the cooler 13 from a stabilizing power source 15 for the thermoelectric cooler causes a decrease in the temperature of the heat-absorbing plane 13a, the heat of the semiconductor section 1 is absorbed to the heat-absorbing plane 13a. The cooler 13 releases the absorbed heat out of a heat-generating plane 13b to a radiator 16. This construction enables the saving of power because of direct cooling of the semiconductor section. Therefore, a cooler of small capacitance suffices, and the device can be markedly miniaturized.

IPC: G11B33/14
Filed: 1995-08-21
Abstract: PROBLEM TO BE SOLVED: To prevent dust, etc., from sticking to an objective lens by providing a means always rotating an optical disk chucked on a turntable. SOLUTION: When the optical disk 6 is inserted into an optical disk device 1 by a loading mechanism, and is placed on the turntable 5 to be chucked, a rotation control means controls so as to continue always the rotation of the optical disk 6 by a spindle motor 4 until an ejection command is issued, and the chucking is released. Then, the optical disk 6 continues to rotate after it is chucked on the turntable 5 temporarily even in the case excepting the times when the data are read or the data are recorded. Thus, the dust, etc., is blown off by wind pressure caused by the rotation of the optical disk 6, and the matter that the dust, etc., is stuck onto the objective lens 11 of an optical pickup 7 is prevented. Further, the dust, etc., stuck to the objective lens 11 is removed also.
