Title: Nonmagnetic ceramics
Inventor: NAKAMURA TSUNEHIKO
IPC: G11B21/21
Filed: 1993-09-30
Abstract: PURPOSE:To obtain nonmagnetic ceramics having excellent processability, an equal thermal expansion coefficient to that of magnetic materials and a low hardness, by mixing MnO and fine particles of CaTiO2 at a prescribed molar ratio. CONSTITUTION:Nonmagnetic ceramics are produced by mixing (A) 91-99 mole% of MnO and 9 to 1 mole% of CaTiO3 having less than 2mum of average particle size. Since MnO having high thermal expansion coefficient is mixed with CaTiO3 of a low coefficient and the average crystal particle size of the latter compound is adjusted to less than 2mum, the resultant coefficient can be made almost equal to that of the magnetic film and the like. Further, the hardness is lower than that of Mn-Zn ferrite. Consequently, when the sliding face of the head where Mn-Zn ferrite is sealed by melting on the nonmagnetic ceramics is mirror- finished the reading and writing ability of the head can be prevented from being lowered because the gap on the Mn-An ferrite part becomes convex.

IPC: F01L13/08
Filed: 1989-09-20
Abstract: PURPOSE:To facilitate machining and assembling by a method wherein a camshaft is formed integrally with a cam and a wheel, a weight and a stay are supported by a support shaft integrally formed on a side surface of the wheel, and a spring is fitted compressively between the weight and the stay. CONSTITUTION:At a starting time, a weight 20 is placed at an imaginary-lined position due to the elastic force of a spring 23 and at a stationary rotating time after the start the weight 20 oscillates around a support shaft 15 in opposi tion to the spring 23 to take a continuous-lined position. At the starting time, since a release pin 16 is protruded from the base circle G of a cam 13 to push up a tappet, a load at the starting time is reduced, and at the stationary rotating time the release pin 16 due to the oscillating movement of the weight 20 turns a cam part which enters the base circle G and the tappet is fitted slidably to the cam 13 so as to allow the stationary rotation of an engine. The support shaft 15 is integrally formed on a cam shaft 11 together with a cam gear 12 and the weight 20 as well as a stay 21 is fitted to the shaft 15 to be sustained by a clip 22.

Filed: 1986-10-15
Abstract: PURPOSE:To detect the leak place of an exhaust system rapidly, certainly and easily, by providing the exhaust system for evacuating a vacuum treatment container and a detection means for detecting the leakage of the exhaust system. CONSTITUTION:A rising pipe 4 and a falling pipe 6 are immersed in the molten steel 28 in a ladle 30 and a vacuum tank 2 is evacuated to allow the molten steel 28 to rise in the vacuum tank 2. Herein, wen inert gas is introduced into the rising pipe 4, the molten steel 28 containing gas bubbles rises in the rising pipe 4 while the molten steel 28 on the side of the falling pipe 6 falls and the molten steel 6 is successively exposed to the vacuum atmosphere in the vacuum tank 2 to allow degassing to advance. When leakage due to cracking is generated in an exhaust pipe 16 by secular change, the open air is sucked in the exhaust pipe 16 to generate vibration in the exhaust pipe 16. This vibration is detected by a vibration sensor 24 to be supplied to a signal processing part 26 and the presence of a leakage place is detected.

Title: Flywheel device
Inventor: NAKAJIMA TOSHIO
IPC: F03G3/08
Filed: 1985-10-31
Abstract: PURPOSE:To protect a casing securely and effectively by absorbing the energy of a broken and scattered rotary body by a rotatable protective ring when a force more than a certain value is applied to said rotary body. CONSTITUTION:A protective ring 22 is rotatably engaged with a casing 21 by means of a leaf spring 23 which is insertedly engaged with the groove 21b of the casing 21, and a stepped part 21a, while an abnormality detecting sensor 25 is insertedly engaged with a hole 22a with both ends of it being connected to a control circuit. If the rotation of the rotary body reaches an unusually high speed of rotation due to the failure of a control unit and the like, the rotary body is broken and scattered due to centrifugal force, being brought into contact or colliding with the protective ring 22. However, the protective ring 22 is rotatable, and is rotated by this contact or collision, absorbing the breaking energy. Furthermore, due to the cut-off of the abnormality detecting sensor 25, dynamic brake is applied to the rotary body, lowering the unusually high-speed rotation. Accordingly, the casing 21 can be protected securely and effectively.

Title: Strip line filter
Inventor: YAMANE KENICHI
IPC: H01P1/203
Filed: 1991-08-29
Abstract: PURPOSE:To obtain the simple and reliable strip line filter with few number of productions by putting a copper sheet which is worked to a resonator pattern shape between two dielectric substrates and adhered by the specific method and forming ground electrodes by plating on the outer peripheral surface of the dielectric substrate. CONSTITUTION:A copper sheet 3 is put between two dielectric substrates 1 and 2, and the copper sheet 3 and the two dielectric substrates 1 and 2 are adhered by the direct bond copper method. Ground electrodes 4 are formed by plating on the outer peripheral surface of the dielectric substrates 1 and 2 removing the part where an I/O terminal 5 formed on the copper sheet 3 is projected, to construct the strip line filter. Accordingly, the I/O terminal 5 is integrally formed by the copper sheet 3, which is projected from the dielectric substrates 1 and 2 and easily connected with the other circuit. Further, the strength of the terminal is powerful enough. Since the resonator pattern is constructed by the copper sheet, it can be formed more easily than forming it by the thick film printing on the dielectric substrates 1 and 2.

Title: Navigation apparatus to be mounted on vehicle
Inventor: KAIHATSU YUJI
IPC: G10L13/04
Filed: 1994-10-11
Abstract: PURPOSE: To set a destination safely and easily even while a vehicle is running by recognizing a word generated correspondingly to the destination among registered points. CONSTITUTION: A driver preliminarily registers a destination for a vehicle to a point-registering means 103, and sets a name of the registered point by a name-setting means 104. When the name is not set, a word and the point are arranged to correspond each other at an initialization step. In setting a course, when the name of the destination or the initially set word is uttered, a voice-recognizing means 105 recognizes the name or word and a course-setting means 102 sets a course including the point corresponding to the recognized word as the destination under the control of a control means 106. For example, an address of the driver's home is registered at 103 and a name 'home' is set at 104. After the setting, when the driver sounds 'home', a course wherein a corresponding point to the sounded 'home' is a destination is set at 102.  In this manner, a complicate setting operation of steps is totally elimnated. Moreover, the driver needs not to look at a screen to set the destination and therefore the driver can concentrate his or her attention on driving, thereby improving safety.

Title: Manufacture of optical wave guide
Inventor: OTSUKA REI
IPC: G02B6/134
Filed: 1986-10-16
Abstract: PURPOSE:To form an optical waveguide which has an uniform and smooth edge similar to an edge formed with a photomask and to reduce the propagation loss of light by forming a 1st mask of a material which is insoluble in a proton exchange solution on a substrate, forming a 2nd mask thereupon, and providing a resist layer thereupon. CONSTITUTION:The edge of the 1st mask 2 is made extremely uniform and smooth by etching similarly to the edge of the mask by a photoprocess, and the line width of the mask is similar to the resist layer. The line width of the resist layer 14 by the photoprocess is determined by the intensity and time of exposure and the time of development, so the line width of the resist can be made invariably constant by fixing them. Consequently, the line width of a proton exchange layer 5 is held constant and further the propagation loss of the manufactured optical waveguide is reduced.
