Title: Noise warning device of motor controller
Inventor: IGARASHI SADAYUKI
IPC: H02P7/00
Filed: 1986-09-12
Abstract: PURPOSE:To provide a simple device for warning that noise is superposed to a command signal by employing a method of indicating and warning that the noise level on a speed signal exceeds a prescribed value. CONSTITUTION:A speed control member 6 performs speed control of a motor 7 corresponding to the deviation between speed command and speed detection values. If the speed command signal with noise superposed thereto is inputted in a high pass filter 2, DC and low-frequency components are filtered and only high frequency components are outputted. This output is converted to an absolute value and smoothed by an absolute value smoothing circuit 3 in the next stage. Further a discrimination circuit 4 discriminates whether the smoothed output exceeds a prescribed value or not, and if it exceeds the prescribed value an indication lamp 5 is lit. In this constitution, it is easily seen that noise exceeding the prescribed value is superposed to the speed command signal.

IPC: G06F3/06
Filed: 1985-09-27
Abstract: PURPOSE:To improve the performance of the processing efficiency, etc., by considering it as an arrival to a terminal area to have run by a prescribed distance from the vicinity of the terminal area of a magnetic tape, when a write system instruction is being executed. CONSTITUTION:An instruction/data prefetch control part of a magnetic tape device has a microprocessor 30, a data transfer control circuit 33, an instruction buffer CBUF, and a data buffer 34, operated as a magnetic tape device against a host controller, and operated as the host controller against a drive control part. In this state, a magnetic tape is run by a magnetic tape drive part, and when an area of the vicinity of a terminal of this tape is detected, the control part measures a running distance of the tape from the time point of the vicinity of the terminal area. When this counting value reaches a prescribed value, it is regarded as a detection of the terminal area of the tape, and a spurious EOT (tape end) is obtained. It has the same effect as a usual EOT detection, an actual EOT marker is not detected, and handling of the EOT can be executed theretofore.

Moreover, the graphite is vaporized and condensed by a laser in the air flow of high-pressure inert gas. Such a lower resist is superior in etching-resistant property and after being subjected to etching, the resist can be easily peeled with oxygen plasma.

Title: Semiconductor device
Inventor: YAMAMOTO JUNICHI
IPC: H04N5/372
Filed: 1991-08-27
Abstract: PURPOSE:To obtain larger output voltage by making the width of a stray diffusion layer narrower than those of an electric charge transfer area and a reset gate electrode situated just below an output gate electrode. CONSTITUTION:When the signal electric charge amount transferred to an electric charge detecting part 2 is referred to as Q and the capacitance of an N type stray diffusion layer 9 as C', the potential change amount DELTAV' of the N type stray diffusion layer 9 is expressed as DELTAV'=Q/C'. Since a P<+> type impurities area 12 is formed on both sides of the N type stray diffusion layer 9, the practical area of the N type stray diffusion layer 9 decreases. So, the capacitance for the part where the N type stray diffusion layer 9 overlaps the second layer polycrystalline silicon electrode 7 adjoining the last stage of an electric charge transferring part 1 with an insulating film in between and for the part where the N type stray diffusion layer 9 overlaps the first layer polycrystalline silicon electrode 6 which is the gate of the transistor whose source is the N type stray diffusion layer with the insulating film in between decrease. The magnitude of an output electric power depends on the scale of a stray diffusion layer, so a larger output electric power can be obtained.

Title: Photomagnetic field type current sensor
Inventor: YAMAMOTO HIDEKI
IPC: G01R33/032
Filed: 1985-09-27
Abstract: PURPOSE:To reduce the shift of the light emitted from a light path forming body at a light receiving point, by arranging a corner cube prism to the other end surface of the light path forming body to reciprocate light in the light path forming body. CONSTITUTION:The light incident to a light path forming body 2 from one end surface thereof is emitted from the other end surface of the light path forming body 2 and reflected by a corner cube prism 4 to be again incident to the light path forming body 2 from the other end surface thereof to issue from one end surface of the light path forming body 2. Therefore, even if the light path forming body 2 is displaced with respect to a light emitting element 3 and a light receiving element 5, the optical axis of the light emitted from one end surface of the light path forming body 2 becomes parallel to the optical axis of the light incident to the light path forming body 2. As a result, even if the light path forming body 2 is displaced with respect to the light emitting element 3 and the light receiving element 5, the positional shift of the light emitted from the light path forming body 2 at a light receiving point can be reduced.

Title: Coil device
Inventor: WAKINO KIKUO
IPC: H01F17/04
Filed: 1987-08-28
Abstract: PURPOSE:To prevent the dispersion of inductance values at every product by inserting a cylindrical elastic body, into which magnetic powder is mixed, into an air core section in a coil and respectively bringing both ends of the elastic body into pressure-contact with the inwall surfaces of ferrite cores. CONSTITUTION:A cylindrical elastic body 8 into which magnetic powder is mixed is inserted into an air core section 1b in a bobbin 1, and the size of the elastic body 8 is designed at a value slightly longer than the height of a housing space formed by ferrite cores 6 and 7. The bobbin 1, a coil 2 and the elastic body 8 are housed between the ferrite cores 6 and 7, and the ferrite cores 6 and 7 are fixed mutually with adhesives, etc. Since the elastic body 8 is designed at the slightly longer value, both ends of the elastic body 8 are in pressure-contact respectively with the inwall surfaces of the ferrite cores 6, 7, and the displacement of the size of a wall section 7b in the ferrite core 7 is absorbed by the elastic force of the elastic body 8 even when the size of the wall section 7b is to some extent displaced, thus generating no gap in all sections between the ferrite cores 6 and 7, between the ferrite core 6 and the elastic body 8 and between the ferrite core 7 and the elastic body 8.

IPC: H01J7/20
Filed: 1983-11-18
Abstract: PURPOSE:To obtain a high-pressure sodium lamp with the stable characteristics by melting and breaking a cadmium container through heating after enclosing in a luminescent tube a capsule-like cadmium container containing amalgam or amalgam and starting rare gas. CONSTITUTION:An amalgam (sodium-mercury) 7 or this amalgam and starting rare gas, which is to be enclosed in the luminescent tube of a high-pressure sodium lamp, is enclosed into a cadmium container 6, which is shaped into a capsule 8. This capsule 8 is enclosed into a luminescent tube bulb 1. After that, by melting and breaking the cadmium container 6, the enclosed materials are brought out. In this way, the reaction of amalgam upon air, water, etc. and the adsorption of impurities prevent the impurities from being brought into the luminescent tube, or further the enclosure of starting rare gas can be simplified and the prescribed enclosing pressure can be surely obtained. Furthermore, during the tube end sealing process in manufacturing a luminescent tube, it is possible to prevent the vanishing of enclosed amalgam due to vaporization through radiant heat, and avoid the deterioration of the lamp characteristics.
