IPC: F16C33/24
Filed: 1987-04-08
Abstract: PURPOSE:To increase the surface rigidity of the captioned bearing by manufacturing the bearing from a composite which mainly consists of plastics and which is compounded with ceramic particles. CONSTITUTION:A plastic bearing is made up of a composite in which ceramic particles having a mean particle diameter of 100mum or smaller are mixed into a synthetic resin in 50-80wt.% Since the mean particle diameter of the ceramic particles is 100mum or smaller, the surface of the bearing is smooth. In addition, the hardness of the particles consisting of ceramic is high enough, and the compounding ratio is kept at as high as 50-80wt.%, which is a maximum that can be held by the synthetic resin. Therefore, the surface rigidity of the bearing can be increased.

Abstract: PURPOSE:To form a lining layer in a desired thickness, by such a simple method that an expansible and contractible bag body is fixed to the leading end of a wire material passed through a pipe. CONSTITUTION:In performing lining, the longitudinal wire material 1a of a wire passing jig 1 is inserted into a pipe 65 in the direction shown by the arrow A along with first and second supply pipes 62, 63.

Title: Reference frequency generation device
Inventor: UJIIE HITOSHI
IPC: G04R20/00
Filed: 1997-04-03
Abstract: PROBLEM TO BE SOLVED: To generate a more accurate and stable reference frequency by allowing an estimation operation part being installed at an operation means for frequency control to receive the detection signal of a temperature in a device and correcting a frequency fluctuation due to a temperature fluctuation quickly. SOLUTION: An ambient temperature detection means 60 detects a temperature in a device and sends the temperature signal to an operation means 13 for controlling frequency. An estimation operation part 22 being installed at the operation means 13 for controlling frequency receives temperature data Tdnew from the ambient temperature detection means 60 and inputs temperature data Tdold that was subjected to temperature correction and was executed last time and then obtains the temperature difference between the both. When the temperature difference exceeds a specific temperature difference Tddiff , a condition is shifted from a normal control state to a temperature correction control state. Then, a relatively fast frequency control is performed to a degree for following a temperature change.  Therefore, a frequency can be corrected even for a short frequency fluctuation accompanying a temperature fluctuation in a device, thus generating a further accurate and stable reference frequency.

Title: Amplifying circuit
Inventor: KIKUCHI AKIRA
IPC: H03F3/20
Filed: 1980-06-23
Abstract: PURPOSE:To achieve an output without distortion, by suppressing the nonlinear change of the circuit power supply determining the signal current. CONSTITUTION:Taking currents flowing transistors (TR) Q1, Q2 as I1, I2 and the voltage on the emitter output line of the TRQ1 as VA, the relation of equations (1), (2) is obtained, where VBE1, VBE2 are the base-to-emitter voltages for the TRs Q1, Q2. From equations (1), (2), the current I2 is expressed as equation (3). Since the current ratio I1/I2 of the TRs Q1, Q2 is always constant alpha, by the reaction of a current Miller circuit 1, VBE1-VBE2 is constant gamma, and the current I2 is expressed as equation (4). That is, the current I2 is independently of the VBE of each TR and the nondistortion signal can be obtained by introducing an output in response to the current I2. Further, in the current Miller circuit 2, when a current which is 1/alpha of the current flowing to the TRQ1, the current flowing to the TRQ6 is equal to the I2, no flowing current fo the voltage source-B2 is present, and the voltage source due to the current change can not be fluctuated.

Title: Crt displayer
Inventor: UENO MASAJI
IPC: G09G1/16
Filed: 1979-07-06
Abstract: PURPOSE: To make possible to visualize faint signals effectively and appropriately by modulating brightness in inverse proportion to the level of received signals.  
     CONSTITUTION: An input signal is amplified by an amplifier 1 and applied to the electrode of a CRT 2, and the bright line is deflected in proportion to the amplitude of the received signal. An arranging circuit 3 arranges the waveform of a received signal, produces a positive or negative DC voltage proportional to the magnitude of the signal, and when modulating the brightness of the Braun tube 2 with this voltage, changes the brightness in inverse proportion to the voltage level, i.e., inversely as the magnitude of the received signal and thus modulates the brightness of the CRT2 so that it becomes brighter when the received signal is weaker.
