Title: Method for machining electron gun parts
Inventor: ENDO SATORU
IPC: H01J9/14
Filed: 1986-07-09
Abstract: PURPOSE:To attempt to improve machining accuracy of a sloped cylinder by making thinner the neibourhood of a part corresponding to the root on a low cylinder side by means of coining process, and applying burring process thereafter so that a thinner plate part remains at the root on the low cylinder side. CONSTITUTION:A thin sheet 12 with sheet thickness (t)' is formed by arranging an waste hole 11, eccentrically to a cylinder central axis Y by the fixed amount S, on a semi-finished electrode 10 moulded into a vessel shape in advance, and applying thereto coining process, concentrically with the cylinder central axis Y, within the limit of an outer diameter D'. Then, coining residues are absorbed in the waste hole 11, making the waste hole diameter smaller into 11(a). After that, a burring under hole 13 is provided while making it eccentric so much as S to the cylinder central axis Y, namely concentric with the waster hole 11, and a burring process is applied to the edge of the hole to complete a moulding of a sloped cylinder 14. At this juncture, the amount of slope of the edge 15 of the cylinder 14 against the cylinder central axis Y can be established easily by fixing eccentric amount S of the burring hole 13, and the rising dimension of a low cylinder 16 relative to that of a high cylinder 17 can also be fixed easily to a required value by changing the dimension of the burring hole 13.

Title: Abnormality detecting system for circuit device
Inventor: KAWADA MASAHARU
IPC: G01R31/28
Filed: 1980-11-14
Abstract: PURPOSE:To make it possible to detect the abnormality of a device, by making such an arrangement that rectangular wave signals are put out at a constant cycle when the device is operating normally, and, when the signals are at the levels of 0 and 1, counting and resetting are performed by respectively different counters. CONSTITUTION:When a circuit device 21 is in a normal condition, 2-position control signals are issued from CPU, etc., that is, rectangular wave signals b1 of a constant cycle 2T2 are continuously put out at equal intervals in conditions of 0 and 1. In first counter circuit 22a, counting is conducted when the output b1 of the device 21 is 1, the counter is reset when the output is 0, and pulses of a built-in constant-cycle pulse oscillator are counted when the counter is in operation. On the other hand, second counter circuit 22b operates conversely to the counter 22a. It is possible, by doing so, to allow counting of either counter to reach above a given value, b2 or b3 of an abnormal signal to be put out to outside and an abnormal signal b4 to be put out through an OR circuit 23, even at the time of occurrence of such an abnormality that a signal b1 keeps holding 0 or 1.

Title: Two-color development method by one-component type magnetic toner
Inventor: TASHIRO JIYUNICHI
IPC: G03G15/01
Filed: 1979-12-11
Abstract: PURPOSE: To form two-color images through two times of development by the use of a one- component type magnetic toner by setting the absolute value of the latent image potential for the  background potential of one latent image so as not to exceed twice the lower limit of the latent  image potential at which the toner can be stuck and forming the electrostatic latent images.   
     CONSTITUTION: This relates to a method of forming the electrostatic latent images of 3-value  levels suited for positive development and reversal development and developing these by using a  one-component type magnetic toners of two colors, wherein the absolute value of the latent image  potential for the background potential V 2  of at least one latent image is so set as not to exceed  twice the lower limit value of the latent image potential at which the toner can be stuck, by making use of the fact that unless the latent image potential exceeds the specific lower limit value the  images are not developed, then at the time of developing the one electrostatic latent image, the  development bias potential VB 3  of the high level latent image is set between the potential of the  other electrostatic latent image differing in charging polarities, for example, the low level latent  image potential V 1  and the background potential V 2 , and the two-color images are formed by two  times of development.

Title: Sector mark detector
Inventor: FUJITA TATSUMI
IPC: G11B20/10
Filed: 1989-06-21
Abstract: PURPOSE:To improve the sector mark detection precision by outputting a sector mark detection signal at the time of coincidence between inputted data and each pattern of a sector mark and stopping the counting operation of each counter with a reset signal at the time of not giving an enable signal to the counter from another counter of the preceding stage. CONSTITUTION:When data indicating a regular sector mark is inputted, respective counters A to N of a detecting counter part 21 count prescribed numbers a' to n' of bits of inputted data '1' or '0' to output enable signals to counters of succeeding stages. Consequently, counters which receive enable signals continue the counting operation though the reset signal is inputted from a reset generating counter part 23, and the sector mark detection signal is outputted by the counter N of the last stage. If data other than the regular sector mark is inputted, the sector mark detection signal is not outputted by the reset signal from the reset generating counter part 23 because enable signals are not outputted from respective counters A to N of the detecting counter part 21. Thus, the precision of sector mark detection is improved.

Abstract: PURPOSE:To improve the exactness of a head weight adjustment by packing the interfused bodies of the expanded hollow microballs formed by expansion of thermally expandable microballs which contain a foaming agent and are formed of a thermoplastic resin as the outside shell component into the internal space of the head. CONSTITUTION:A prescribed amt. of the thermally expandable microballs 2a which include the foaming agent (e.g. isobutane) and are formed of the thermoplastic resin (e.g. vinylidene chloride/acrylonitrile copolymer) as the outside shell component are packed into the internal space 1a from a forzel hole, 1b of the head 1. The microballs 2a are expanded by heating to pack the internal space 1a with the interfused bodies 2 of the expanded hollow microballs 2b. This method is not only the revolutionary technique in terms of the exactness and workability of the adjustment of the head weight but also much superior to the conventional polyurethane foam packing system in terms of the quality, performance and reliability of the resulted product.

Title: Laminated inductor
Inventor: SUZUKI YASUO
IPC: H01F17/00
Filed: 1998-06-09
Abstract: PROBLEM TO BE SOLVED: To improve reliability of a laminated inductor, by reducing fluctuation of the L-value caused by deviated printing of a conductor pattern and, at the same time, ensuring connection between conductor patterns or between the conductor patterns and external electrodes. SOLUTION: A laminated inductor is constituted by alternately printing and laminating electric insulating layers 1 and conductor patterns 2 upon another, and forming coil patterns superimposed in the laminating direction by successively connecting the end section of each conductor pattern 2 to each other and the beginning and the end of the coil patterns 2 to external electrodes 3 and 3. Each coil pattern is formed by combining a U-shaped pattern 2-2 with an I-shaped pattern 2-3. When the combination of the I- and U-shaped patterns is used, the characteristics of the coil is stabilized, because the influence of deviated printing on the cross section becomes smaller and fluctuation of the L-value is suppressed.
