Title: Parity error detection system
Inventor: KUBO NAOTO
IPC: H04L1/00
Filed: 1988-12-29
Abstract: PURPOSE:To execute descrambling in one descrambling circuit without switching scramble patterns at a reception side by generating any descramble patterns, which correspond to plural types of scramble patterns at a transmission side and respectively have the same number of '1' in a parity interval. CONSTITUTION:In an intermediate repeater station 1, after a received signal a+s is demodulated in a demodulator 2, the frame synchronization of the signal a+s is obtained in a frame synchronizing circuit 3. The signal a+s from the frame synchronizing circuit 3 to reach a modulator 4 is modulated and after that sent to the station of the succeeding stage. Since descramble patterns d1 and d2 are set so that both d1 and d2 can have the same number of '1' in the same parity interval, regardless of the coincidence/noncoincidence between a scramble pattern (s) of the signal a+s sent from the transmission side and the descramble pattern d1, a descramble circuit 5 outputs a signal (b) having the same parity number as that of data (a). Consequently, accurate interval parity counting can be executed only by equipping the station 1 with one descrambling circuit 5.

Abstract: PURPOSE:To manufacture a collector suitable to a lead accumulator having a high energy density by etching a lead or lead alloy foil stuck to an acid resisting film into a collector form, and making a negative electrode plate thinner than a positive electrode plate by etching. CONSTITUTION:A laminated film of a lead or lead alloy foil 4 and an acid resisting film 3 having polyethylene as an outer layer is prepared, an etching resist 5 is formed on the lead or lead alloy foil side surface of the laminated film, etching is conducted by use of a mixture of acetic acid, hydrogen peroxide and water, and the resist is then removed by caustic soda aqueous solution or a solvent such as trichlene. Thereafter, the etching resist is again formed only on a positive electrode collector 1, a negative electrode collector 2 is etched to make the negative electrode collector 2 thinner than the positive electrode collector 1, and the resist is removed to make the positive and negative electrode collectors 1, 2. Thus, the volume ratio and weight ratio of the active material to the whole battery are largely improved, and the energy density of the battery can be enhanced.

Title: Transmission
Inventor: JIEIMUZU RIN HOURUMAN
IPC: F16N7/38
Filed: 1995-11-30
Abstract: PROBLEM TO BE SOLVED: To efficiently distribute lubricant to several types of gears and bearings in a vehicle transmission by arranging a pump in a housing. SOLUTION: Lubricant is absorbed inwardly from an oil reservoir formed at the lower part of a transmission housing 14 by the rotation of an inside member 82 and an outside member 81. The lubricant is then passed through a channel 61 to a grooved hole at the entrance of a pump, formed through a bearing holding plate 70, and absorbed into the pump 80. The lubricant moves from a port 63a through a third channel 63 up to an internal passage and flows into a hole formed in an internal wall 14b of a transmission housing 14 in the axial direction. The lubricant is supplied to the entrance of a lubricant release pipe 12, pushed from the entrance through a first release leg and jetted from the hole into an region of engagement of gears of main portions with one another.  The jetted lubricant drops from the engaged gears due to its gravity and stays in the oil reservoir formed at the lower part of the transmission housing 14. The lubricant is thus efficiently distributed.

Title: Single mode optical fiber directional coupler
Inventor: ISHIKAWA TOSHIHIKO
IPC: G02B6/28
Filed: 1987-12-29
Abstract: PURPOSE:To improve the extinction ratio of an optical fiber directional coupler to the ratio much higher than the extinction ratio of the conventional coupler by constituting the input/output ends of said coupler as coil type optical fiber polarizers and operating these polarizers to maintain the absolute single polarization plane. CONSTITUTION:The optical fiber input/output ends of the optical fiber directional coupler 8 are wound at the prescribed bending radius where the absolute single polarization wavelength region exists to constitute the coil type optical fiber polarizers 9. The bending losses of the elliptic jacket type polarization maintaining optical fiber 2 are such that one of the incident waves at the axes of polarization intrinsic to the two directions (X polarized wave and Y polarized wave) is a low loss and the other is a high loss. Only the incident waves of the low loss, therefore, propagate in such coil type optical fiber polarizers 9 formed by winding the optical fibers at the prescribed bending radius so that the polarizers operate to maintain the absolute single polarization plane. The stresses in the polished part are thereby eliminated and the loss of the large extinction ratio of the elliptic type polarization maintaining optical fiber 2 is obviated.

Title: Phase modulation method and apparatus
Inventor: DONARUDO SHIYUMADERU
IPC: G02B6/00
Filed: 1989-12-26
Abstract: PURPOSE: To provide larger phase modulation to signal energy of a given quantity by transmitting electromagnet radiations into an etched optical fiber and elongating or compressing this optical fiber in a longitudinal direction. CONSTITUTION: For example, a submersible acoustic sensor is immersed into a soln. contg. acoustic signals. The periodic changes of the pressure appearing in the acoustic signals expand or contract a soft thin film 7-9. The etched single mode optical fiber 8-9 is elongated or contracted in compliance with the expansion or contraction of this thin film 7-9. The electromagnetic radiations propagating the inside of the core of the fiber 8-9 are, therefore, modulated. The single mode fiber is elongated or contracted in the longitudinal direction by using the one signal energy in such a manner, by which the changes are induced in the optical distance of the optical fiber. As a result, the phase modulation of the larger quantity of the light propagating in the core is obtd.

Title: Curve formation and correction on computer display
Inventor: NEWELL MARTIN E
IPC: G06T11/80
Filed: 1997-12-05
Abstract: PROBLEM TO BE SOLVED: To form and correct the curves on a computer display by mapping the free control point of a curve against a point set on a line for demarcation of a correction curve, projecting the value of the correction curve at each point for the calculation of an enlargement/reduction ratio, and multiplying the enlargement/reduction ratio by the displacement of a selected point for the decision of displacement of the free control point. SOLUTION: A curve is demarcated by plural control points, and each control point is identified as a fixed control point, a selection control point or a free control point. Then the displacements of plural selected points are received. The free control point of the curve is mapped to a point Tp set on a line (t). A correction curve IC (t) is demarcated on the line (t). The point Tp is projected to the value of the curve IC (t) with t=Tp satisfied for detection of a scale factor, i.e., an enlargement/reduction ratio, and this ratio is multiplied by the displacement of a selected point for decision of displacement of the free control point.

Title: Fuel injection quantity controller for diesel engine with supercharger
Inventor: TAKAICHI KAZUHIKO
IPC: F02D23/02
Filed: 1987-12-29
Abstract: PURPOSE:To make good engine starting performance securable by installing a fuel limiting lever release mechanism which leads atmospheric air into a vacuum actuator at the time of starting increment requirement. CONSTITUTION:When supercharging pressure is less than the setting one, a maximum injection quantity is regulated to a specified rack position by regulation of a fuel limiting lever 41, through which an oversupply of fuel is prevented from occurring for a while till the supercharging pressure goes up. When a key switch 70 is operated to a start contact point 72 hereat, a pressure switch 45 keeps up its OFF state, but since both switch parts 76a, 76b and a rotary switch 79 all come to an ON-state, a solenoid part 66 is energized with current and thereby atmospheric air is led into a vacuum chamber 53 from an inlet part 61 by a selector valve 42. With this atmospheric air, a vacuum actuator 40 operates and the fuel limiting lever 41 rotates, and thus a governor lever 7 is rotated to the fuel increment side. Consequently, a starting increment spring 28 is effectively serviceable so that a fuel starting increment at the time of engine starting is thus secured.
