Patent JP-S62261625-A (JP)
Title: Fuel injection control device
Inventor: NAGANO MASAMI
IPC: F02D41/04
Filed: 1985-11-27
Abstract: PURPOSE:To prevent the variation in an engine speed so as to obtain riding comfort, by predicting the data immediately after the present time, based on the data on the engine speed, intake air flow, etc, up to the present time, and, from the values thus predicted, determining the valve-open-period immediately after the present time. CONSTITUTION:Output signals from an air meter 3, a distributor 16, etc. are input into a control unit 15. In this unit 15, by using three pieces of past data T2, T1, and T0, where T2 denotes the ignition period at the latest-but-two ignition; T1 denotes the ignition period at the latest-but-one ignition; and T0 denotes the ignition period at the least ignition, the ignition period T after two times of ignition is predicted through the quadratic-curve-approximation. Similarly, with regard to the intake air flow, the mean intake air flow QA after two times of intake air strokes is predicted, using the three pieces of past data. Based on both T and QA thus obtained, the basic injection pulse width Tp is obtained. Than, by correcting this Tp-value, the output pulse width Ti is calculated. Next, the pulse width Ti is set to a register, and an injector 13 is kept open for a period of time Ti for fuel supply. Accordingly, the way of supplying the fuel matches the intake air stroke from now, thereby reducing the variation in the engine speed. Thus, the riding comfort can be ensured.

IPC: G11B5/706
Filed: 1985-11-27
Abstract: PURPOSE:To improve the frequency characteristics of the titled medium in the region of long recording wavelength by forming the deep layer part of a magnetic layer with a material having higher magnetic permeability than the surface layer. CONSTITUTION:A high-permeabiity layer 2 made of a high-permeability Ni-Fe magnetic alloy such as 'Permalloy(R)' is used as the deep layer close to a base 1 and forming the magnetic layer along with a magnetic recording layer 3 used as the surface layer part. Accordingly, a magnetic field corresponding to recording information is brought over to the deep layer, and a long- wavelength signal is deeply recorded. Consequently, the frequency characteristics in the region of long recording wavelength is improved, and a magnetic recording medium having frequency characteristics with excellent linearity over the range from the long-wavelength region to the short-wavelength region is obtained.

Title: Throw-away diaper
Inventor: YOSHIKAWA MASAHIKO
IPC: A61F13/494
Filed: 1988-10-21
Abstract: PURPOSE:To prevent the leakage of the thigh and the side in a throw-away diaper improved in its fitness for movement by providing a hydrophobic property in both side parts of a surface sheet, arranging two or more elastic members respectively in the lengthwise direction between an absorbing layer and both side parts of the throw-away diaper and coating the elastic member in the outermost part with the above described hydrophobic location of the surface sheet. CONSTITUTION:A diaper is prepared by placing an absorbing layer in the center of a polyethylene sheet 3 and two elastic members 4, 5 in one side within 50mm from the end of an absorber in its lengthwise direction being coated with a surface material 5 of size equal to the polyethylene sheet. The diaper is prepared by folding in the inside the absorbing layer 2 in a position 20mm from an edge part of the absorber in its lengthwise direction and adhesively mounting 50mm the central part with an adhesive agent. Here the absorbing layer 2 uses polymer of high absorptivity. The surface material uses a hydrophobic fiber such that both side parts of the hydrophobic fiber, previously forming all the surface hydrophilic by processing with alkyl phosphoric ester serving as the hydrophilic oil, is washed by hot water. Since the diaper is fitted to the thigh by this elastic member, no leakage of the thigh and the side is generated.

Abstract: PURPOSE:To make braking pressure holdable in optimum conditions irrespective of a road surface angle, by making flexible piping material in front and in the rear of a valve so as to be deformed by operation of a valve angle adjusting device and to be adjusted to the specified angle as the valve is rotated. CONSTITUTION:Each flexible piping material 25 being free of deformation is interposed in front and in the rear of a check valve 11 in the point midway in a brake pipe line 8, allowing movements of the pipe line with rotation of the valve 11. Therefore, a knob 24 is operated whereby the check valve 11 is rotated so that it is adjustable to the specified angle. In consequence, it is able what with to be set in horizontality and what with to be set in left-hand down by pushing the knob 24 from this horizontal state and to be set in right- hand down by pulling the knob 24. Thus, at a braking pressure holder, the setting angle is optionally selectable, so that an optimum angle can be set easily even in an uphill, a downhill and a flat road, thus an optimum brake holding state is securable by the setting angle.

Title: Optical fiber capable of emitting light in transverse direction
Inventor: KITAGUCHI HIROMASA
IPC: F21V8/00
Filed: 1986-11-08
Abstract: PURPOSE:To widen the light emitting area of an optical fiber and to arrange optical fiber on a plane so as to eliminate the necessity of any deep space, by cutting the end face of the fiber in an oblique direction and providing an uneven surface for refracting and reflecting light on the cut face. CONSTITUTION:The light 6 which enters an optical fiber 1 in the direction shown by the arrows advances through the fiber 1. The light is then bent at the uneven surface 3 of a notched section 2 and projected from the fiber 1 in the transverse direction. If the notched section is made to have an elongated area, therefore, the light emitting surface of this optical fiber 1 becomes larger and a larger quantity of light can be seen. When the uneven surface is worked to have a striped pattern in case of making the surface rougher and to make diffused reflection as frosted glass does in case of making the surface finer, a more effective result can be obtained. When an optical fiber is worked in such a way, its light emitting area can be made larger and easily seeable and, at the same time, no deep space is required because the optical fiber can be put in a plane without bending it.

IPC: H01L27/108
Filed: 1987-10-21
Abstract: PURPOSE:To facilitate easily the formation of a connection part with excellent controllability, by a method wherein, after only a region, in which the connection part of a side wall surface of a groove is formed, is coated with an oxidation-resistant film, and the inner surface of other groove is selectively oxidized, the oxidation- resistant film is eliminated, and the surface of the connection part is exposed. CONSTITUTION:A shallow groove 16 is formed, by selectively eliminating a PSG film 15, a poly-crystalline silicon film 14, an SiO2 film 2 and a silicon substrate 1, in the manner in which a part of an element isolation region formed on a P-type silicon substrate 1 is penetrated. By oxidizing the inner surface of the groove 16, a thin SiO2 film 17 is grown, and further a silicon nitride film 18 is deposited. By anisotropic etching, the film 18 is eliminated and left only on the side wall of the shallow groove. Then, a deep groove is formed, by anisotropically etching the SiO2 film 16 and the lower substrate. By thermally oxidizing the side wall of the deep groove, an SiO2 film 3 is formed on the inner wall, but the side surface 9' of a connection part coated with a film 18 is not oxidized at all. By eliminating the film 18, and further eliminating the thin film 17 on the region 9' surface, the silicon surface on the side wall is exposed. By forming a polycrystalline silicon electrode 4 so as to contain said surface, connection is completed.
