IPC: E04B1/61
Filed: 1999-03-02
Abstract: PROBLEM TO BE SOLVED: To provide an extruded shape suitable for the frictional agitation welding by the rotation of a rotary body. SOLUTION: In a structure body, end parts of a welded part of hollow shapes 50, 60 have outwardly projecting thick-walled parts 56, 66. Two thick-walled parts are butted to each other to form a trapezoidal shape. Rotating bodies 70, 70 are inserted in the thick-walled parts 56, 66, and rotated and welded with each other. A large diameter part 71 of the rotary body 70 is rotated in a condition where it is located outward of the extension of the external surfaces of general plates 51, 52, 61, 62.

Title: Measuring unit for sedimentation velocity
Inventor: SHIRAISHI TAKASHI
IPC: G01N15/05
Filed: 1979-05-01
Abstract: PURPOSE:To perform the measurement with good accuracy without personal opinion of measuring personnel, by measuring the sedimentation speed such as blood through the use of linear photo electric conversion element. CONSTITUTION:The blood 1 is set to the measuring tube 1. When the sedimentation is started, only the part of blood plasma which transmits much light is appeared near the upper liquid surface. Since this part transmits light well, the light from the light source 5 is received at the photo electric conversion element group 4, and the boundary position between the part having lower transparency including much solid content such as red corpuscle and the part almost consisting of the liquid such as blood plasma only can be detected. Since this signal is picked up as an electric signal, the automation of calculation can be made.

Therefore, even when the toner patch is irradiated with the light at the time of detecting the concentration, the light is prevented from being absorbed in the transfer intermediate body. Thus, the transfer intermediate body and the black toner patch are accurately discriminated and the concentration is accurately detected in the case of forming the black toner patch on the transfer intermediate body.

Title: Crystal oscillator
Inventor: TAKEUCHI TAKASHI
IPC: H03B5/32
Filed: 1987-03-10
Abstract: PURPOSE:To obtain a crystal oscillation which does not generate a feed-back oscillation and is stable by fixing the output of a crystal oscillator to an L level, H level or high impedance until a signal from a timer circuit is received, in the crystal oscillator having a crystal oscillating circuit, plural amplifiers and the timer circuit in the internal part of an IC. CONSTITUTION:When a power source 17 rises, the power source is supplied to the whole of a circuit. For a drain terminal 9 of a crystal oscillating circuit, the crystal oscillation is gradually grown and a time (t) passes after the power source rises, and then, the amplitude is grown up to the power source voltage. Since the output is fixed at an L level during the time (t), the noise due to the action of the output is not fed back to the oscillating circuit. When the time (t) passes after the power source rises, a timer circuit 8 switches a timer circuit output 12 from the L level to an H level, a NAND gate 12 opens the gate and thus, a crystal oscillating frequency is outputted. Since the output is operated, the noise is fed back to the crystal oscillating circuit and a drain amplitude is grown up to the power source voltage, and therefore, the influence of the noise is not received.
