Title: Vacuum heat insulating material
Inventor: SASAKI TAKAHARU
IPC: F25D23/06
Filed: 1998-03-27
Abstract: PROBLEM TO BE SOLVED: To facilitate automation by placing an adsorbent for adsorbing moisture, carbon dioxide gas, or the like, in the recess of a core material thereby preventing dropping of the adsorbent from the core material. SOLUTION: A recess 1a is cut mechanically in a core material 1 and then chips are removed by means of an air rope, or the life, or a heated iron-like metal of same shape as the recess 1a is applied to the core material 1 thus shaping the recess 1a. In case of substantially planar or fibrous adsorbent 2, irregularities are suppressed on the finished surface of a vacuum heat insulating material thus reducing the possibility of scratching or breaking the wrapping material during machining process or at the time of assembling into a product, e.g. a refrigerator. In case of a particulate or pellet-like adsorbent 2, it is inexpensive as compared with a substantially planar or fibrous adsorbent 2 and suitable for economical mass production because it can be fitted easily in the recess of the core material.  A laminate film is folded and thermally fused on two sides and then a wrapping material 3 is applied thereon and thermally fused on three sides to produce a bag into which the core member 1 internally arranged with the adsorbent 2 is inserted.

IPC: H01L29/786
Filed: 1990-03-28
Abstract: PURPOSE:To to prevent the generation of a defective while the effect of the improvement of a TFT characteristic, which are hydrogenerated, is maintained and to make it possible to correspond to an increase in the size of a substrate by a method wherein a cap layer of a diffusion coefficient of hydrogen smaller than that of a polyimide layer, which is used as an interlayer insulating film, is formed on an amorphous silicon film and hydrogen existing in the amorphous silicon film is eliminated from the amorphous silicon film by a heat treatment and is diffused. CONSTITUTION:An amorphous silicon film 108 is formed by a plasma CVD method or the like. A cap layer 109 is formed on the film 108 and a hydrogeneration annealing is performed at a temperature of 300 to 500 deg.C or thereabouts. Atomic hydrogen is eliminated from the film 108 by the annealing, is diffused in a stopper layer 107 or an interlayer insulating film 110, a gate electrode, a gate insulating film 102 and a semiconductor region and combined with terminal free-bond parts existing in a polycrystalline silicon grain boundary or the like. Since the hydrogenation is conducted by atomic hydrogen eliminated from the amorphous silicon film by annealing, a BT stress is hardly applied at the time of formation of the film 108 and the generation of a defect due to plasma damage can be perfectly eliminated.

Title: Device for delivering sheet-form article from laminate
Inventor: YOSHIMURA KATSUAKI
IPC: B65H1/22
Filed: 1991-03-18
Abstract: PURPOSE:To prevent the damage of a sheet-form article and breakage of the article owing to buckling when the article is delivered in a displaced state in a delivery direction by displacing the upper surface of a belt upwardly above the under surface of a laminate in a rear in the delivery direction of the laminate. CONSTITUTION:In a rear position in the delivery direction of a laminate 53, the upper surface of a belt 63 is displaced upwardly above the under surface of the laminate 53. When the belt 63 is driven in a running-round manner, blank sheets punched out 54 are delivered in a state to be displaced in the delivery direction and overlapped with each other through a gap between a doctor 56 and the belt 63. Thus, a force by means of which the blank sheets 54 are pressed against the rear surface in the delivery direction of the doctor 56 can be kept at a constant low value and the warp of the blank sheets 54 is prevented from occurring. Since the force by means of which the blank 54 is delivered through the gap between the doctor 56 and the belt 63 is kept at a constant value, the delivery state of the blank 54 is stabilized, and the blanks are delivered in a state to be reliably displaced from each other and overlapped with each other.

IPC: E21B47/18
Filed: 1994-03-28
Abstract: PURPOSE: To expand a measuring capability in drill by allowing a ground telemeter unit to communicate through a mud channel. CONSTITUTION: A down-link control signal from a ground processor 36 of a ground telemeter unit 14 is transferred to the down-link data encoder/modulator of a down-link transmitter 24. The encoder/modulator outputs the down-link control signal to the adaptive servo controller of a down-link mud pulsar as the on/off tone modulated control signal. An up-link data signal and the down- link control signal are formed in different frequency ranges, and therefore, they can be frequency-multiplexed, and simultaneously transmitted to inverse directions in a mud channel 16. Thus, a measuring capability in drill can be expanded.

Filed: 1989-03-30
Abstract: PURPOSE:To measure vibration with high accuracy by controlling the vibration of a support stand so that a beam splitter or the like become a vibration-free state and measuring only the vibration of a object to be measured by a photodetector. CONSTITUTION:The transmission laser beam having frequency f0 transmitted from a laser transmitter 6 is split by beam splitters 7 - 9 and one of the split laser beams advances straightly to reach an object 70 to be measured and receives the effect of the vibration of the object 70 to be measured to become a reflected laser beam which in turn returns to the splitters 7 - 9 as well as reaches photodetectors 11, 12 by reflection. The other split laser beam is reflected in a right-angled direction by the splitters 7 - 9 and not only refracted in the vibration direction of the object 70 to be measured by a reflecting mirror 10 but also reflected by a beam reflecting body 1 to return to the splitters 7 - 9 to reach the photodetectors 11, 12. As a result, since the beam reflecting body 1 receives the vibration of a support stand 5 to control the extension and contraction of a piezoelectric body 4 and a control gain can be set so that the beam reflecting body 1 becomes a vibration-free state, the frequency of the laser beam reflected by the beam reflecting body 1 is held to f0 as it is.

Filed: 1979-06-29
Abstract: PURPOSE:To prevent the fluctuation of the amount of incident rays which is caused by the fluctuation of the scanning speed, by giving the control the level of the picture signal by the mark density signal and the reference signal. CONSTITUTION:The mark is attached to the roller, and thus the shift amount of the scanner is detected by the mark sensor. In other words, video signal VO is supplied to input terminal X of multiplying circuit 61, and the output signal is compared with reference level E at operational amplifying circuit 64. And the differential output is supplied to input terminal Y of circuit 61 through change- over switch 65. In this case, the both inputs of circuit 61 are referred to as X and Y along with the output signal referred to as Z respectively. Thus Z=K.X.Y (K: a constant) is specified, and the operation is given so as to secure the constant Z. And sample holder 63 holds the signal proportional to the reciprocal number of the video signal at the time point when the sampling order is received. The signal showing the ratio to the level corresponding to the mark is delivered to output terminal Z of circuit 61. This reference level is renewed every scanning and proportional to the amount of the incident rays. As a result, the output signal gives no effect to the fluctaution of the velocity for the scanning period.
