Title: Head shell
Inventor: TERAMAE KAZUO
IPC: G11B33/12
Filed: 1984-05-18
Abstract: PURPOSE:To easily confirm that whether or not the present ambient temperature is the optimum to the capacity of a pickup cartridge, by providing an indicating element which changes its color according to the temperature to a head shell. CONSTITUTION:An indicating element 12 which changes its color according to the temperature is provided at the top of the head shell 8 of a pickup cartridge. Since the appropriate working temperature of the pickup cartridge is fixed, a substance which changes its color in the vicinity of 20 deg.C is used as the indicating element 12, if the appropriate working temperature is 20 deg.C. By checking the color of the element 12 before using, measures, such as raising the ambient temperature, increasing the stylus pressure, and so forth, can be taken when the ambient temperature is low. When the ambient temperature is high, the opposite measures can be taken. Therefore, the capacity of the pickup cartridge can be brought out easily to the maximum. Moreover, when various kinds of indicating elements having different color changing temperatures are used and an optimum stylus pressure indicating section 13 corresponding to each indicating element 12 is provided, the ambient temperature and stylus pressure can be controlled easily.

Title: Automatic focusing device
Inventor: KONISHI KAZUKI
IPC: G03B13/36
Filed: 1987-04-24
Abstract: PURPOSE:To obtain an automatic focusing device having high focusing rate by substantially discriminating main objects in the respective scenes from the result of range finding to plural points and at the same time focusing on the main object at high rate based on the result. CONSTITUTION:In an active distance measuring system, light beams are sequentially radiated, for example, from three light projecting elements 1a, 1b and 1c. Then the reflected light beam from the object are received in an light receiving element 3 and their focal lengths are arithmetically processed as following by an MPU 6 so as to focus. Namely, the MPU 6 computes the focusing position from the average value of three points such as the nearest point, the middle point and the farthest point if these three points are set in approximate lengths. If the farthest point is an infinity, the MPU 6 decides that it is not information shown by the main object and removes it, then computes the focusing position from the average value of two point. Since the focus is adjusted to be brought thus, the automatic focusing device having high focusing rate can be obtained.

Filed: 1991-04-05
Abstract: PURPOSE:To attain high speed processing by changing a threshold level for each main scanning line in the error spread method in which errors are distributed only in the main scanning direction and selecting a period of the threshold level change to be 2n+ or -1 so as to suppress noise with a period of the threshold level change. CONSTITUTION:A picture input 1 is given to an adder 3, in which error data are added to the input and the result is inputted to a comparator 5. A threshold level is read from a memory 12 or each line by a line synchronization control circuit 13 and the threshold level is stored in advance in the memory 12 so that a period of a threshold level change for each main scanning line is to be 2n+ or -1. The threshold level is compared with the input data at the comparator 5 and a binarized output depending on the comparison quantity is stored in a buffer memory 9 and a difference between input output data is calculated as an error by a computing element 6. The error is delayed by one picture element at a delay circuit 11 and a weight coefficient is multiplied with the error by a weight circuit 7 and the product is inputted to the adder 3, in which the result is fed to a succeeding picture element. Thus, it is not required to provide an error buffer memory, the circuit configuration is simplified and the processing is quickened.

Title: Sliding contact material
Inventor: FUJISHIMA SUSUMU
IPC: C22C5/00
Filed: 1983-06-08
Abstract: PURPOSE:To improve the wear resistance of a conventional sliding contact material consisting of Pt, Pd, Ag and Cu by adding specified amounts of Sb and one or more among In, Ti, Tl and Zr to the contact material. CONSTITUTION:An alloy material having a composition consisting of, by weight, 0.1-1% Pt, 42-44% Pd, 39-41% Ag and 15.5-17.5% Cu has been widely used up to now as a sliding contact material, especially as a material for a brush contact. A brush contact of the alloy material shows, however, inferior wear resistance during sliding along a commutator and causes the generation of noise. In order to improve the wear resistance, 1-10% Sb and 0.3-3% one or more among In, Ti, Tl and Zr are added to the alloy material without changing the ratio in the composition. 0.01-0.5% Fe group metal may be further added.

Title: Magnetic bubble chip used for both major/minor loop and single loop
Inventor: NOGAI KENGO
IPC: G11C19/08
Filed: 1978-08-22
Abstract: PURPOSE: To ensure the use of the same chip for both the major/minor loop and the single loop just by changing the flowing way of the control current for the transfer gate.  
     CONSTITUTION: Plural units of minor loops m... are distributed in parallel to one unit of major loop M, along with installation of bubble generator G, replicater S, bubble detector D and bubble eraser A each. The loop features the major/minor loop, and two-way transfer gate Ts is formed between the major loop and each minor loop. When the loop is used as the major/minor loop, the control pulse is  flown to gate Ts only at the transfer action. While the control current is flown  every time and in synchronization with the driving waveform in case the loop is  used as the single loop chip. As a result, the bubbles can be shifted serially like the  single loop chip. Furthermore, the cost can be reduced since one divice can be used  for both purposes.

Abstract: PURPOSE:To suppress the generation of a noxious component in exhaust gas, by varying the fuel cut time at deceleration according to the degree of deceleration. CONSTITUTION:The degree of opening THtheta of a throttle valve is read at a step 100. A deviation DELTATHtheta between the preceding and the present degree of opening of the throttle valve is found at a step 102. The degree thereof is determined at a step 104. The larger the deviation DELTATHtheta is, the higher is the degree of deceleration, and if it is determined at the step 4 that the deviation DELTATHtheta is equal to or more than DELTATHtheta1, the fuel cut time corresponding to the deviation DELTATHtheta is calculated at a step 108. This permits the suppression of the generation of a noxious component in exhaust gas.
