Title: Error correction system
Inventor: YAMAGATA MANABU
IPC: G11B20/18
Filed: 1988-04-06
Abstract: PURPOSE:To correctly correct a data error independently of the occurrence location of the data error by referencing a future syndrome value, applying reset when the value is zero and not applying reset when not zero. CONSTITUTION:When an error due to an internal pointer exists in a 9th frame, an error track cannot correctly be detected and the correction capability is deteriorated. Then when a reset condition of a pointer (for example, no error exists in 7 consecutive frames) is established, the vertical and tilt syndrome values of the succeeding frame are processed by a syndrome processing unit 10 and when the value is zero, a point circuit 6 is reset through a pointer reset signal line 11, and when the value is not zero, a pointer reset control signal 13 is used to avoid the reset of the pointer circuit 6. Thus, the data error is corrected surely independently of the location of occurrence, the error is corrected surely and the correction capability is improved.

Inventor: FURUKAWA AKIO
IPC: H01L27/095
Filed: 1988-04-06
Abstract: PURPOSE:To increase switching rate, by using GaSb having high hall mobility for a P-channel high electron mobility transistor (HEMT) and InAs having high electron mobility for an M-channel HEMT. CONSTITUTION:An N-channel HEMT comprises an electron supply layer of AlxGa1-x and an electron transist layer of InAs, while P-channel HEMT comprises a hall supply layer of AlxGa1-xSb and a hall transit layer of GaSb. Since electrons in the InAs have mobility about four times as high as that of electrons in GaAs, the N-channel HEMT thus produced is operable at high speed. Further, since halls in the GaSb have a mobility three to four times as high as that of halls in GaAs, the P-channel HEMT thus produced is operable at high speed. The complementary HEMT consists of an N-channel HEMT composed of a gate layer 1 and an N-channel layer 2 and a P-channel HEMT composed of a gate layer 4 and a P-channel layer 5. The HEMT thus produced is allowed to have increased switching speed.

Abstract: PURPOSE: To improve power source power factor and reduce power source capacity  and magnetic moise, by providing two sets of rectifiers, which are connected to two  sets of AC power sources, in a device to excite an electromagnet, which attracts  objects, and operating firing control of thyristors by the output of one side at the  time of normal control.  
     CONSTITUTION: Excitation of electromagnet 15, which attracts object 16 is operated by the output of rectifiers 13, 14, which rectify respectively the AC outputs of motor-generator 12, which is provided with two sets of generators. At the time of normal control, voltage is supplied from rectifier 14 to electromagnet 15. The output voltage of generator 12 is determined by the condition which permits the operation of thyristors 14aW14f provided in rectifier 12 in the neighborhood of the conducting angle of 0 and the voltage required by the load. Thus, the ripples of output voltage Ed 0  of rectifier 14 are reduced, and the voltage is impressed on electromagnet 15 via either one of the two arms connected in series to rectifier 13. Thus, the output voltage power source power factor of generator 12 is improved, the power source capacity is reduced, and at the same time, noise produced by electromagnet 15 is reduced.

Title: Prescaler circuit
Inventor: KITADA YOSHITAKA
IPC: H03K23/64
Filed: 1983-05-13
Abstract: PURPOSE:To reduce the useless working current of a prescaler circuit by stopping the action of a dividing circuit in case a count signal other than a dividing signal is selected by a selecting circuit. CONSTITUTION:An AND gate 3 is connected to the input of a dividing circuit 1, and the output of an AND circuit 3 is always set at logic ''0'' when the logic value of the 2nd selection signal SEL2 is set at ''0''. Thus it is possible to stop the action of the circuit 1 by a means which stops the clock input to the circuit 1. The working current of the AND gate of the means which stops the action of the circuit 1 is very small. Therefore the working current obtained when a dividing signal DIV1 is selected by a selecting circuit 1 is equal to that of a conventional prescaler circuit, i.e., 200muA. However the action of the circuit 1 is stopped when both 1st and 2nd clock inputs CI1 and CIN2 are selected. Thus the power consumption of the dividing circuit 1 is reduced almost down to ''0''. As a result, the working current is reduced down to about 1/10, i.e., 20muA.

Abstract: PURPOSE:To obtain a collimation optical system which is small is size and light in weight and projects an image of superior quality by using a Fresnel lens and giving the Fresnel lens a progressive focus. CONSTITUTION:The collimation optical system of optical equipment for light projection uses the Fresnel lens 3, which is given the progressive focus. The light emitted by a light source 1 is connverged by a reflecting plate 2 and sent to the Fresnel lens 3 and light passed through the lens 3 is passed through a transmission type liquid crystal display body 4, diverged by a projection lens group 5, and projected on a screen 6. The focal length f3 of the part distant from the center of the Fresnel lens 3 for light convergence is close to the focal length f2 increases successively toward the center of the lens. Consequently, more light is converged at the peripheral part of the transmission type liquid crystal display body 4 which has low brightness. The brightness of the peripheral part of a projection image is improved and the collimation optical system which is superior in the quality of the projection image is obtained.

Abstract: PURPOSE:To fulfill the offset preventing function and prevent a releasing agent from sticking to a pressure roll, by forming the section of the tip of a metalling blade to an R shape in the part facing an image region and forming it to an edge shape in the part facing a non-image region. CONSTITUTION:The section of the tip of a metalling blade 11 facing an image region LY of a heat roll 2 is formed to an R shape 11a, and that facing a non- image region LN of the heat roll 2 is formed to an edge shape 11b. If the section of the tip facing the image region LY is formed to the edge shape also, an applied releasing agent is all scraped off because a force in the direction of rolling-in of the metalling blade 11 acts when the heat roll 2 is rotated; however, since the section of the tip facing the image region LY is formed to the R shape 11a the releasing agent is leveled uniformly without stemming it even if this force acts. Meanwhile, the part of the edge shape 11b is compressed to the part of the non-image region Ln, and the releasing agent in this part on the heat roll 2 is scraped and stemmed forcibly.
