Title: Color picture tube
Inventor: SHISHIDO AKIRA
IPC: H01J29/07
Filed: 1984-02-15
Abstract: PURPOSE:To obtain a mechanically strong and less doming shadow mask by making the front and rear surface holes of the openings of a shadow mask equal in size. CONSTITUTION:A front surface hole 3a and a rear surface hole 3b are each made, for example, hemispherical and approximately equal in size. In this condition, when the thickness of a shadow mask plate, the radius of an opening 2, and the radius of the front surface hole 3a are fixed, theta can be made larger as compared to the case of an existing shadow mask, providing a tolerance to the occurrence of reflected electron beams and light exposure. When the radius of the opening 2, the radius of the front surface hole 3a, and theta are fixed, the shadow mask plate can be made thick and mechanically strong and the doming can be reduced; thus the picture quality can be improved.

Title: Sleeve type gas spring
Inventor: COTTER JONATHAN P
IPC: F16F9/02
Filed: 1999-02-03
Abstract: PROBLEM TO BE SOLVED: To provide a gas spring having characteristics, that is it is compact, it can produce a strong force and it can have a long use life. SOLUTION: A sleeve type gas spring in a turret index-feed type press machine incorporates an annular piston which is operatively associated with an annular piston and a reciprocating punch tool, and defines a part of an annular gas chamber for receiving a pressurized gas. When the punch tool and the piston are moved to an extended position by a ram in the press machine, the volume of the gas chamber is decreased so that the pressure in the gas chamber is increased, and accordingly, during retraction of the ram, the piston and the punch tool are moved to a retracted position by the pressure of the gas in the gas chamber. Accordingly, the contraction force of the sleeve type gas spring can be simply changed by changing the pressure of the gas in the gas chamber.  Further, the gas spring has an extremely long use life, and can be simply recharged therein with gas, and a seal which is even worn out excessively, can be simply replaced with new one, thus it is possible to simply repair the gas spring.

Title: Transmission power amplifier circuit
Inventor: TAKENAGA KOTARO
IPC: H03F3/24
Filed: 1991-01-29
Abstract: PURPOSE:To compensate the temperature of a transmission power amplifying transistor TR by detecting the temperature of this TR to apply the detection voltage to a DC amplifier circuit and using the output as the reference voltage of a bias stabilizing power source. CONSTITUTION:A positive temperature detecting element 6 is closely brought into contact with a transmission power amplifying TR 1 to always detect the temperature of the TR 1. In the case of a normal temperature, the temperature detected by the element 6 is converted to a voltage and is converted to a low impedance by a DC amplifier 8 for the purpose of facilitating the control and is inputted to a DC amplifier 7 and is used as the reference voltage output to operate a stabilizing power source 5. When the temperature of the TR 1 rises, the voltage detected by the element 6 rises, and the reference voltage drops, and the bias voltage drops also, and the output of a power amplifier is reduced. When the temperature of the TR 1 is reduced, the output of the power amplifier rises by the opposite operation. Thus, temperature compensation of the power amplifier is possible. Variable resistors 9 and 10 are adjusted to obtain the temperature compensation characteristic most suitable for the TR 1.

IPC: E01C11/02
Filed: 1998-02-09
Abstract: PROBLEM TO BE SOLVED: To provide an expansion joint to sufficiently absorb approach between the end parts of bridges due to elongation of a bridge and an earthquake, and having excellent vehicle runability. SOLUTION: An expansion joint spanning between bridges H and H positioned facing each other has a groove extending at an orthogonal direction to the direction of a bridge axis and having elastic members 1 formed in an upper and under surfaces. An elastic part between an approaching groove 10 on the upper surface side and a groove 11 on the under surface side forms a deformation part 12. When the bridges H and H approach and part from each other, the width of the groove on the upper surface side is contracted and expanded along with shear deformation of the deformation part 12. In this case, a compression deformation part 13 further easily deformed than the constituting material itself of the elastic member 1 is arranged at the elastic member 1 part separated away from the groove 10 on the upper surface side based on the groove 11 on the under surface side.

Abstract: PURPOSE: To determine the property of water without subjecting it to frequency scanning, by detecting a pulse which has been applied to a solution to be passed through an insulating tube, and subjecting to Fourier conversion an induction voltage output obtained by the mentioned detection operation.  
     CONSTITUTION: A solution 4 is passed through an insulating tube 1 which is provided on its outer circumferential surface with parallel-arranged plate type excitation electrodes 2 and a detection coil 3. An impulse or a step pulse is applied to the excitation electrodes 2 and detected by the coil 3 to obtain an induction voltage output. This output is then subjected to Fourier conversion in a data processing section 9 consisting of a preamplifier 6, a primary amplifier 7 and a Fourier conversion unit 8, so as to be divided into frequency components (including resonance frequency). The permittivity of the solution is determined in a low density region thereof, and the conductivity in a high density region. Both the permitivity and conductivity are determined in an intermediate density region. The property of the solution is then evaluated. The pulses in use mentioned above are an impulse far shorter than the reciprocal of the resonance frequency, or a step pulse which rises extremely rapidly.
