Title: Stria measuring instrument
Inventor: ISHII TOMOYUKI
IPC: G01N21/958
Filed: 1993-04-02
Abstract: PURPOSE:To accurately measure striae by rotating a sample of optical quartz glass, etc., against a point light source and an optical path, such as a screen, etc., and making the striae in the sample parallel to the optical path. CONSTITUTION:The light having passed through a pinhole 8 passes through a sample on a sample mount table 9 and forms a variable-brightness image on a photographic paper table 10 relevant to a screen. When the variable- brightness image is indistinct due to out-of-focus, the locking means 9c of the table 9 is released and the table 9 is rotated until the image projected on the base 10 becomes distinct. When the distinct image is obtained, the table 9 is fixed to a supporting base 9a by means of the locking means 9c and, at the same time, an incandescent lamp 6 is temporarily turned off. Under such a condition, photographic paper is set on the table 10 and the photographic paper is exposed to the light from the lamp 6 for a fixed period of time so as to print the variable brightness on the paper by again turning on the lamp 6. From the distinct variable-brightness image printed on the paper, the internal striae of the quartz glass, etc., are measured.

Title: Thin-film multielement magnetic head
Inventor: KOSHIMOTO YASUHIRO
IPC: G11B5/31
Filed: 1981-06-27
Abstract: PURPOSE:To obtain a thin film head having high accuracy, high sensitivity and a large allowance current, by securing a specific angle theta to the traveling of an opposite medium for the substrate plane of a multielement magnetic head and at the same time specifying the repetitive interval of a magnetic head to a track pitch. CONSTITUTION:A substrate plate 3 forming a multielement magnetic head is set so as to secure an angle theta of inclination (theta<=30) to the traveling direction of a magnetic recording medium (toward an arrow mark). Under such conditons, a head core 1 is formed. The repetitive interval CP of the head 1 is set as CP= TP/sintheta to the track pitch TP of the recording medium, and at the same time almost right angles (80-100 deg.) are secured for the gap of the head 1 to the traveling direction of the mangetic recording medium. In such a way, a multielement magnetic head having a high recording current value, high reproducing sensitivity is obtained in a simple way and with high accuracy although the pitch TP is reduced.

Title: Adjusting method for control parameter for controller
Inventor: TANAKA TAITARO
IPC: G05B13/02
Filed: 1994-04-13
Abstract: PURPOSE:To adjust a control method with the simple method by calculating the value of the control parameter corresponding to the sensitivity and cycle of critical vibrations when only an integration gain is increased and when only a proportional gain is increased. CONSTITUTION:Concerning the adjusting method for control parameter at the time of I-PD control to a gas turbine 4 as a controlled system, for example, first of all, a static gain is measured by a static characteristic test. Next, the sensitivity and cycle of critical vibrations at the time of increasing only an integration gain KI of an integration element 1 and the sensitivity and cycle of critical vibrations at the time of increasing only a proportional gain Kp of a proportional element 2 are measured. Then, the optimum adjusted values of the integration gain KI, proportional gain Kp and differentiation gain Kp are calculated corresponding to these measured results. Thus, while using the simple method similar to the critical sensitivity method of Ziegler Nicols, the control parameter can be adjusted at the optimum value even concerning any controlled system to which this critical sensitivity method can be applied.

Title: Artificial land type residence
Inventor: HIGASHIHATA YASUO
IPC: E04H1/00
Filed: 1992-04-21
Abstract: PURPOSE:To improve the safety of each residence against its collision at the time of an earthquake in an artificial land type residence where a detached house is built as a secondary structure on a multilayer artificial land floor which is a primary structure and composed of a pillar, a beam and a floor. CONSTITUTION:The floor part 3a of the second floor of a house 3 is abutted (or supported in a contacting state) upon the pillar on an artificial land through a shock eliminating member 4. Horizontal force acting on the house 3 (secondary structure) at the time of an earthquake is dampedly lessened by the shock eliminating member 4. Thus, since the extreme collision force of the house 3 does not act on the pillar 1 of a primary structure, and the impulsive force of the house 3 is lessened to be weak, the earthquake resistant safety of the whole of the artificial land is not damaged, and the uneasy feeling of an inhabitant in the house 3 is therefore not thoughtlessly increased to obtain good living comfortableness in the house 3.

IPC: G11B27/36
Filed: 1984-05-18
Abstract: PURPOSE:To display with switching accurately both output level at reproduction and the number of skipped music at a skip music selection mode with a small number of display elements by using a common display element. CONSTITUTION:A changeover switch 5 is set at A when a display element is actuated for the display of a reproduction level. Thus a level detecting circuit 7 turns on the display elements 6 successively in response to the detected level. The reproduction level is displayed by the number of display elements 6. Then the switch 5 is changed to a terminal B to actuate an automatic skipping music selection circuit 9. A music interval detecting circuit 8 delivers a pulse every no-sound part (music interval) of a reproduction output. Then the circuit 9 turns on successively the display element 6 up to a prescribed count number with the pulse signal given from the circuit 8. Thus the number of skipped music is displayed with high accuracy.

Title: Current limiting type non-contact ignition device
Inventor: FUJINO HIROYO
IPC: F02P3/05
Filed: 1985-05-15
Abstract: PURPOSE:To prevent oscillation of constant electric current by working current- limiting transistors for controlling the base current for a power transistor in the active area within the current limiting section of the current limiting type non-contact ignition equipment. CONSTITUTION:When alternating current signal Vp from an electromagnetic pick-up coil 4 turns from positive to negative, output from a control circuit part 5 becomes large, turning off a transistor 19 and turning on a power transistor 22. Then, voltage decline at the primary current detecting resistor 15 steps up, and when declining voltage at a resister 12 in the standard voltage circuit (8, 11, 12, 17, 18) and the resister 15 becomes almost equal, the transistor 20 is turned off and a transistor 21 is turned on. Due to this, the transistor 21 draws the base current of the power transistor 22, thereby putting current limiting function into full play, but if the drawing of base current goes too far, power decline portion at the resister 15 diminishes, thereby turning on the transistor 20. At this time, however, the current flowing through the resister 16 also flows through the base for transistor 21, resulting in avoidance of switching actions on the part of the transistor 21.

IPC: G01D5/347
Filed: 1987-04-24
Abstract: PURPOSE:To detect a length high in resolution by detecting alight beam which has transmitted through slits arranged on a screw-like disk. CONSTITUTION:Slits are arranged on the periphery of a screw-like disk 2, and by placing this disk 2 between, a light source 1 is placed on one side, and a detector 3 is placed on the other side. When the disk 2 is brought to a screw rotation, a light beam which is emitted from the light source 1 and has transmitted the slits is detected by the detector 3, and from a count value of its output, a moving extent of the screw-like disk 2 is derived. That is, by the product of this count value and the resolution obtained by dividing the pitch length of the disk 2 by the number of slits on one round, a value of the length is measured.
