Title: Dust core excellent in frequency characteristic
Inventor: YURI TSUKASA
IPC: H01F1/22
Filed: 1987-03-23
Abstract: PURPOSE:To hold the fixed AC initial magnetic permeability up to a high-frequency region by a method wherein in a dust magnetic core based on pure iron powder or iron alloy powder, its powder form is specified to heighten a magnetic characteristic such as the AC initial magnetic permeability and the density of a magnetic flux. CONSTITUTION:Pure iron powder or iron alloy powder and an insulating binder are used to form a dust magnetic core. At the time, the powder is made into flat powder having average value not less than 3.0 of the value of the ratio of the maximum diameter l to the thickness (b) l/b and not exceeding 350 mesh. Refining of magnetic core forming powder reduces an eddy-current loss of the magnetic core so as to improve a frequency characteristic. On the other hand, in the flattening of powder, the longitudinal direction and the thickness direction of flat powder are easy to be matched with the right-angled direction and the horizontal direction respectively to the pressure direction at the time of pressure molding and accordingly, the void among the compact composing powder is small compared with that of a compact of the conventional indefinite and spherical powder. That is to say, the dust density is increased, a magnetic characteristic such as the AC initial density is heightened while holding the fixed AC initial magnetic permeability up to a high-frequency region.

Title: Control device for hydraulically-operated type transmission
Inventor: FURUKAWA HIDEO
IPC: F16H61/68
Filed: 1995-03-02
Abstract: PURPOSE: To prevent worsening of fuel consumption through prevention of the occurrence of surging and to simplify an oil pressure control circuit by providing an oil pressure regulating means to regulate the feed of an oil pressure to a frictional engagement element and a slide control means to control the friction engagement element to a slide engaging state through an oil pressure regulating means during non gear shift. CONSTITUTION: In control, even during non gear shift, the slip of the hydraulic clutch Cη, the speeds of which are established, of hydraulic clutches C1, C2, C3, and C4R is controlled. In this case, a value QJUA equivalent to a feed oil pressure is first increased to a high value and secondly, the value is gradually decreased. At a point of time when it is detected that a slide amount is reduced to a value lower than a given value, the value is returned to an increase and controlled to a given slide amount. As noted above, since the hydraulic clutch Cη is slid to absorb surging, the lockup clutch L of the torque converter may be controlled only to two positions of the one being complete engagement and the other being complete disengagement, and constitution of an oil pressure control circuit is simplified.

Filed: 1986-03-27
Abstract: PURPOSE:To make a distortion element stably separable from the inside of a magazine where it is aligned vertically, by installing a chamfer in a partition plate at the downstream side in a work flowing direction. CONSTITUTION:This device is provided with a pusher 4 which extrudes each work 2 being stacked and aligned in a magazine 3 and whose section is made into a chevron shape, having a convex part 4a insertable into a concave part of a partition plate 1a.

Abstract: PURPOSE:To contrive substantial improvement in indexing and mounting accuracy by a method wherein a cylindrical body in which a plurality of pellets are laminated and housed, is used. CONSTITUTION:When the pellet-mounting part 22' of a lead frame 22 is fed intermittently at a point below a cylindrical body 16, the entire cylindrical body 16 is lowered to the lower dead point where the pellet 15 of the lowest layer  will be approaching the fused solder 24 on the mounting part 22'.

Filed: 1992-02-18
Abstract: PURPOSE:To achieve appearance as an extremely dark object image which exists on a bright plane and then facilitate visual recognition according to the difference in contrast by casting light coaxially with the direction of observation. CONSTITUTION:When a surface smooth projecting object is observed from a direction which is vertical to a plane by casting light coaxial with the direction of observation, it is observed as an extremely dark object image which exists on the bright plane within the observation visual field since a vertical incidence light which impinges on the plane is reflected in the direction of a light source while light is reflected on the object due to surface smoothness but the light axis of the reflection light is not regular and nearly does not return to the direction of light source. In this device, a half mirror 2 is provided at an optical system of a monochrome television camera, an illumination light from a light source 5 is bent at right angle and is observed via the half mirror 2 from the direction of light axis of illumination light.
