Title: Precision vibration control method for table and the like on which precision instruments are installed
Inventor: HATAYAMA TAKAYOSHI
IPC: F16F15/02
Filed: 1990-03-14
Abstract: PURPOSE:To precisely control external vibration in a short time by damping vibration with large amplitude by means of both a variable spring and a variable damping device, and executing active control thereafter in such a way that vibration is changed into small displacement in vibration with a piezo- actuator driven when vibration amplitude becomes less than specified one. CONSTITUTION:A table 4 for the installation of precision instruments is supported over a foundation 1 by the use of a piezo-actuator 5 using piezo-electric elements, a variable spring 2 and a variable damping device 3. Both of the variable spring 2 and the variable damping device 3 are controlled by a control device 8 in response to signals from a detector 6 for coarse motion, which is provided over the table 4, and the piezo-actuator 5 is diven by a control device 9 in response to signals from a detector 7 for micro-motion. When external vibration is applied to the foundation 1, vibration is damped first by a passive or a semi-active control mechanism. In this case, the control device 9 is out of action, the control device 9 however is not allowed to be in operation before the vibration amplitude of the table 4 becomes 100 mum and less, micro- vibration is therefore damped by means of active control.

Title: Solid-state image pickup device
Inventor: KOUCHI TETSUNOBU
IPC: H04N5/369
Filed: 1998-03-12
Abstract: PROBLEM TO BE SOLVED: To completely transfer charges in a photodiode to a floating diffusion part, by applying the output of a potential setting means to the gate of a transfer switch means and the gate of a reset switch means, and controlling them so that optimum potential can be set. SOLUTION: A first potential setting circuit 502 sets the signal voltage of a control signal generated in a control pulse generation circuit 504 and applies it to a transfer gate 501. A second potential setting circuit 503 sets the signal voltage of the control signal generated in the control pulse generation circuit 504 and applies it to a reset gate 12. The voltage of the gate 501 of transfer MOS is controlled from a first potential setting circuit 502 independently of the voltage of the gate 12 of reset MOS. Then, optimum potential can be set. Thus, the prescribed quantity of transfer charges can be secured and prescribed sensitivity can be kept.

Title: Optical reproducing system
Inventor: NAKAGAWA SHIROU
IPC: G11B7/12
Filed: 1981-04-24
Abstract: PURPOSE:To increase the SN ratio with increased peak value of laser beam, by irradiating a laser beam for reproduction with pulse modulation in a frequency more than twice the reproduced frequency. CONSTITUTION:A signal generator 1 turns on or off a semiconductor laser with a pulse signal in 100MHz and the laser is irradiated on a recording medium 5 via optical systems 4a and 4b. After a detected light from the recording medium 5 is photo-electriccally converted at a photodetector 6, the said pulse signal component is removed at a low pass filter 8 via an amplifier 7. Since pulse modulation is given to a laser beam 3 of the semiconductor laser 2, although the energy given to the recording medium is the same at the case without pulse modulation, the peak value is greater, the SN ratio at reproduction is increased, and this system is suitable for the reproduction of a high sensitivity recording medium.

Title: Rotary drum device
Inventor: KIDO TAKESHI
IPC: G11B5/588
Filed: 1988-03-14
Abstract: PURPOSE:To enable a head to exactly track the recording marks even in case the feeding speed of a magnetic tape is optionally changed at reproduction by forming a projection at a part where the yoke of a gimbal spring is bridged and at the same time a contact is secured the yoke or a part of the yoke corresponding to the former part. CONSTITUTION:The gimbal springs 5 and 6 having projections 12 are held between the yokes 9, 10 and 10, 11 respectively. The these projections 12 are plastically deformed when the fixing screws 14 are tightened. Thus both springs 5 and 6 are adhered to the yokes 9-11 via the plastically deformed projections 12 and at the same time a drive part 3 is fixed on an upper drum 2. As a result, the areas around the bridged parts between the springs 5 and 6 and the yokes 9-11 are fixed to these yokes with no gap produced. Thus no backlash is produced when a head 4 is moved in the width direction of a magnetic tape in accordance with the tape feeding speed V2. Then the linearity and the reproducibility are improved for the shift value of the head 4 to the control current supplied to a cylindrical coil 7.

Abstract: PROBLEM TO BE SOLVED: To smooth the discharge of a product. SOLUTION: A product discharge outlet structure is provided for a biaxial kneader in which two kneading shafts are inserted through a cylindrical casing in its cylindrical shaft direction, and a material to be processed is introduced from one end upper face of the casing into the casing and a product is discharged from the other end lower face of the casing. The discharge outlet 10 is formed of a nozzle member A fitted into the casing, and the nozzle member A is divided into inner and outer members 10a and 10b with an edge 13 as a boundary, and the divided members are integrated together by fitting protruded line/channels 14a and 14b. A plurality of members 10a of different discharge outlet diameters are provided, and one member 10 of the diameter optimum for the product is used as a replacement. The discharge outlet 10 is formed of a circular section 11 and an oblong section 12, and its boundary is the edge 13. As the discharge outlet is of the circular shape, the adhesion of the product to corners is not generated. As the flow of the product to be discharged along the inner face is shut off by the edge 13, the product is passed through the larger oblong section 12, and the product is hardly in touch with the inner face of the discharge outlet 10 and also the adhesion thereon is controlled. The circular section 11 can be deformed eccentrically to the side of one kneading shaft.

Title: Pcm terminal station equipment
IPC: H04Q11/04
Filed: 1992-03-19
Abstract: PURPOSE:To send information used to prevent a call from being inputted to an exchange. CONSTITUTION:A detection circuit 3 extracts an 8-bit signal in a number 16 time slot in a number 0 frame from a PCM signal based on a timing pulse. A discrimination circuit 5 outputs a DLC signal when a level of a 5th bit, a 7th bit and an 8th bit in a received bit signal from the detection circuit 3 is all logical 1. A time slot detection circuit 4 detects signaling bits a, b, c, d of each channel of the number 16 time slot in frames whose numbers are 1-15 from the PCM signal based on the timing pulse. When the discrimination circuit 5 outputs the DLC signal, a control circuit 6 checks the signaling bits a, b, c, d and converts the signal into blocking information when the signaling bits indicate idle information. Thus, the further input of a call to the exchange is blocked and intermission of a voice signal attended with a limit of a DCME is prevented.
