Title: Driving device of voltage control type photoswitch
Inventor: FUKUSHIMA TOMIO
IPC: G02F1/31
Filed: 1979-07-24
Abstract: PURPOSE: To improve reliability by driving a voltage control type photoswitch with the rectified output of a self-exciting type inverter as an electric power source for photoswitching and an electric power source for signal generator.  
     CONSTITUTION: The DC output of an electric power source section 6 consisting of a self-excited inverter inputs to a photoswitch 7 via a transistor 8. A signal generator 10, with the DC output of the electric power source section 6 as its power source turns a transistor 8 on and off according to the control signal from input terminal 10. The input terminals 7a, 7b of the photoswitch 7 are connected to the input terminals 11a, 11b of a photocoupler 11 and the output termianls 7c, 7d are connected to output terminals 11c, 11d. A magnetooptic effect comprising, for example, lead glass, is used for the photoswitch. When the high voltage from the electric power source section 6 is applied to the photoswitch 7 according to the output signal from a signal generator 10, the output of the output terminals 7c, 7d is annihilated by the rotation of the polarization plane of light, whereby switching is accomplished. The electric power source section 6 operates on low voltage input and since the effect of leak current is prevented via a transistor 9, reliability is high.

Title: Reciprocal arithmetic unit
Inventor: NAKAYAMA TAKASHI
IPC: G06F7/552
Filed: 1988-04-18
Abstract: PURPOSE:To shorten the time required for a reciprocal arithmetic operation by carrying out two retrieving actions, one multiplying action and one adding or subtracting action to the reciprocal data corresponding to the input data on a memory means as well as to the square data on a reciprocal after the higher and lower rank bit data related to the input data are delivered from a dividing means and calculating the reciprocal. CONSTITUTION:The N-bit input data a1 is divided by a dividing means into a 1st divided data H consisting of higher M bits and a 2nd divided data L consisting of lower (N-M) bits (a1=H1+L1). A memory means stores previously the reciprocal data and the square data on a reciprocal. Then the memory means has the output of the corresponding reciprocal data 1/H1 and the square data 1/H1<2> on the reciprocal with input of the 1st divided data H1. While a multiplication means performs the multiplication between the 2nd divided data L and the data 1/H1<2> to output of the multiplication data L1/H1<2>. Furthermore the addition/subtraction means subtracts the multiplication data L/H<2> from the reciprocal data 1/H1 to obtain the subtraction value (1/H1-L1/H1<2>) and produces a reciprocal 1/a1 of the input data (a). Thus the arithmetic time is shortened.

Title: Composite magnetic head
Inventor: KOYA AKEMASA
IPC: G11B15/62
Filed: 1988-04-18
Abstract: PURPOSE:To prevent a tape from meandering and to improve the head touch of tracks near edge parts on both the sides of the tape in a multitrack head by inclining a pair of heads in opposite tape width directions and fitting them. CONSTITUTION:One magnetic head 1 is so inclined that its one end in the tape width direction may be close to the tape and the other end in the tape width direction may be apart from the tape and the other magnetic head 2 is inclined at the same angle opposite to the magnetic head 1 to the magnetic tape. Here, the tape runs on a head contact face whose section is an opened U shape (a shape curved like a bow). Thus, the meandering of the tape can be prevented without increasing tape tension. Especially the head touch of the tracks near the edge parts on both the sides of the tape can be improved satisfactorily, troubles such as off-track and dropout can be removed and outputs at the time of recording and reproducing can be improved.

Title: Longitudinal cutting method of ingot
Inventor: OSADA SHIYUUJI
IPC: B22D11/126
Filed: 1979-07-27
Abstract: PURPOSE: To enable the cut ingot having no flashes and bends to be obtained at minimum metal  losses and by high speed cutting, in a method of rolling groove portions in a high temperature  ingot with rolls having annular projecting parts then cutting the same by gas, by specifying the  remaining thickness of the above-described groove portions.   
     CONSTITUTION: A high-temperature ingot S is rolled with groove portions in cutting positions  with rolls R having annular projecting parts 1, whereby it is reduced of thickness, after which it is  gas-cut by a torch 3. At this time the remaining thickness of the groove portions is kept ≤60mm.  This remaining thickness is more desirable as it is thinner in terms of the exposure of the ingot  inside, sticking of slag, etc. owing to gas cutting, but excessive reduction in thickness results in  increased pass times and rapidly increased roll reducing time. At other than this, the thickness- reducing time does not become the rate-determining step of the entire process and the gas cutting  time can become the rate-determining step. Hence, the need for cutting one 10m ingot in 2.5min  arises owing to the maximum casting time etc. On the other hand, the cutting time is proportional  approximately to the above-described residual thickness as shown in the graph, hence the remaining thickness is defined as ≤30mm but as ≤60mm by considering the case for cutting the ingot  longitudinally with two cutters.

Title: Method and device for encoding image
Inventor: KIMURA YOSHIMASA
IPC: H04N19/46
Filed: 1989-04-17
Abstract: PURPOSE:To obtain a decoding image whose picture quality is scarcely deteriorated by obtaining a decoding image by taking the sum of an image brought to pan or tilt in accordance with a moving amount to a decoding image of one frame before a pan and a tile are started on a receiving side, and a difference image. CONSTITUTION:When a pan and a tilt are started, a signal from a code input terminal 15 is decomposed to a pan/tilt parameter and image data by a separating circuit 16. The extracted pan/tilt parameter is decoded by a pan/tilt parameter decoding circuit 21, and simultaneously, a second switch 22 is connected to the side of a fourth terminal 24. As a result, a second pan/tilt circuit 25 generates a signal brought to pan or tilt by using the pan/tilt parameter with respect to the decoding signal before the pan and the tilt are started. Accordingly, the sum of the signal brought to pan or tilt, and the image signal inputted from the code input terminal 15 and obtained by the separating circuit 16 is calculated by an adder 17. In such a way, a decoding signal brought to pan or tilt is obtained in a decoding signal output terminal 18.

Abstract: PURPOSE:To ensure the function of a hood lock provided to a resin bulkhead even though an impact which can slightly deform a bumper is exerted. CONSTITUTION:A hood lock 6 provided at the upper end of a resin bulkhead, for locking the front end of a front hood 17 is connected to a cross member 2 of a vehicle body frame F through the intermediary of a metal stay 12. Even if a small impact which cannot deform the cross member 2, is exerted to a bumper 5, the hood lock 6 does not lose its function since the stay 1,2 does not pull the hood lock 6. If a large impact is exerted so as to break the bulkhead 4, a front hood 17 is prevented from being opened since the hood lock 6 is restricted by the cross member 12 through the stay 12.

Title: Amber color phosphor
Inventor: MEGUMI KOUICHI
IPC: C09K11/08
Filed: 1983-05-30
Abstract: PURPOSE:To provide a single-component phosphor in amber color with a high luminance which consists of a specified Ca-Mg-Mn-S compsn. and causes no Cd pollution. CONSTITUTION:The phosphor is represented by the formula, where x is 0.3-3.8 (mol) and y is 0.35-1.0 (mol). In the area where Mn is in high concn., marked lowering of phosphorescence takes place. In this case, a desired chromaticity coordinate is obtained in the area where attenuation of the phosphorescence is low and the luminance is increased with a consistent color tone, if Mn concn. is lowered by addition of Mg. When Mg is added while Mn concn. is maintained constant, attenuation of the phosphorescence is lessened, although the phosphorescence energy effect is decreased slightly. A preferred condition to obtain a high-luminance phosphor is to choose a combination of Mg and Mn concns. corresponding to the luminance along curve 12.
