Title: Oil seal member
Inventor: KUDOU MATSUKIKU
IPC: F16J15/3252
Filed: 1986-01-31
Abstract: PURPOSE:To prevent an abrasion loss in the seal lip of an oil seal ring and improve sealing quality through the prevention of the seal lip from being overheated. CONSTITUTION:The seal lip 15b of an oil seal ring 15 is slidably in contact with the external surface of a rotary shaft 12 in a posture inclined to the lengthwise direction of said shaft 12. When the rotary shaft 12 rotates, therefore, the contact part 15c of the seal lip 15b and the external surface of the rotary shaft 12 gives a reciprocating motion within a certain range in an axial direction and frictional heat occurring at said part 15c is dispersed. Concurrently, an abrasion loss in the contact part 15c of the seal lip 15b is reduced because of the oil content of an oil film generated between the seal lip 15b and the external surface of the rotary shaft 12 due to a wedge effect.

Title: Noise shaping circuit
Inventor: AKAGIRI KENZO
IPC: H03M7/30
Filed: 1990-01-31
Abstract: PURPOSE:To attain a noise shaping processing not affected by ON/OFF of emphasis by controlling the characteristic of a noise filter in response to an output de-emphasized after preemphasis. CONSTITUTION:An output of a pre-emphasis circuit 10 is fed to a control circuit 42, which is provided with a de-emphasis circuit 41 whose characteristic is correspondent with that of the pre-emphasis circuit 10. Then the filter characteristic of a noise filter 30 is controlled by a coefficient control circuit 40 in response to the output of a de-emphasis circuit 41. Thus, the spectrum shape of the signal whose high frequency characteristic is emphasized by preemphasis is restored to the original spectrum shape by the de-emphasis and the filter coefficient is controlled based on the signal of the original spectrum shape. Thus, a reproduced sound with excellent listening sense not affected by on/off of the emphasis is obtained.

IPC: G06F3/0354
Filed: 1990-01-31
Abstract: PURPOSE:To miniaturize a data input device and to improve its portability by constituting this data input device in ball-point pen type structure, detecting the density or flow velocity of ink at the periphery of a ball in four directions with four sensors, and transferring X-axial and Y-axial motion components to an outside. CONSTITUTION:The four sensors Xa and Xb, and Ya and Yb detect the density of the ink 11 between a shaft 10 and the ball 12. When the ball is in a stationary state, the density of the ink detected by the sensors at four positions are uniform. When the device is moved, the ball 12 in contact with the surface of paper is rotated o draw a line. At this time, the four sensors detect the density of the ink and sends their outputs to an arithmetic means 1. The means 1 calculates the motion components in both the X-axial and Y-axial directions of the motion of the data input device according to the density data. Then a transfer means 2 converts the arithmetic data to format which enables an external device such as a computer to recognize the data and then transfers the converted data. Consequently, the device is miniaturized and improved in portability.

IPC: H04B7/26
Filed: 1994-02-18
Abstract: PURPOSE:To clearly identify whether the error is due to a cause outside the service zone or due to interference by another system by judging a telephone call circuit state based on the comparison between the number of slot errors and average values of received levels in the measurement block. CONSTITUTION:An antenna 31 of a master set B receives a transmission signal S10 from an antenna 11 of a slave set main body A, and a radio communication circuit 32 converts the signal into a base band signal S14 and it is given to a reception data processing section 34. Then the processing section 34 gives a control signal S14 to a control section 38 and gives digital audio signal 16 to an ADPCM section 35. Then an error discrimination section 39 discriminates a status of a telephone line based on the comparison between a slot error number and a received average level for a measurement block to discriminate the error. The status is fed to the control section 38, which gives each information to an error data processing section 41 and a level data processing section 42, in which the information is processed internally. Thus, the control section 38 identifies whether the occurrence of error is due to a cause at the outside of the service zone or due to interference by other system.

Abstract: PURPOSE:To reduce the influence of a discrepancy between the lattice constant of an active layer and the lattice constant of clad layers at their operation by a method wherein the lattice constant of the active layer, the lattice constant of a p-type clad layer and the lattice constant of an n-type clad layer are constituted under specific conditions at the time when an electric current is applied and at the time when it is not applied. CONSTITUTION:When the lattice constant of an active layer is designated as A, the lattice constant of a p-type clad layer is designated as Ap and the lattice constant of an n-type clad layer is designated as An, the relationship of either Ap<A<An or Ap>A>An is kept at the time when an electric current is applied and at the time when it is not applied; their respective lattice constants at the time when the electric current is not applied are set in ranges of ¦Ap-A¦/A<=3X10<-3> and ¦An-A¦/A<=3X10<-3>. For example, an n-buffer layer 2 of n-GaAs is grown on an n-type substrate 1 composed of Si-doped GaAs at a substrate temperature of 750 deg.C in order to prevent that a defect such as a dislocation or the like on the surface of the substrate 1 is propagated to clad layers. An n-clad layer 3 of n-InGaAlP, an active layer 4 of InP an a p-type clad layer 5 of p-InGaAlP are grown sequentially on it. In addition, a p-cap layer 6 of p-GaAs is grown on it.
