Title: Color signal processing circuit for vtr
Inventor: TANAKA KENTA
IPC: H04N9/83
Filed: 1989-12-19
Abstract: PURPOSE:To make a control loop stable in a short period of time by limiting a lower level so as to prevent a control voltage of a voltage controlled oscillator from being decreased from a prescribed value in a frequency control loop in a circuit frequency-converting a color signal at the reproduction of a VTR. CONSTITUTION:A detection output of a phase comparator 7 detecting a phase difference between a chroma signal demodulated in a chrominance subcarrier fsc and a stable frequency signal from an oscillator 6 is fed to an automatic phase control filter 8 via a lower limiter 20. The output of the filter 8 is fed to an operational amplifier 10 and fed to a plus side input terminal of a subtractor 9. The operational amplifier 10 compares the output of the filter 8 with the level of a constant power supply 11 and gives the comparison output to a minus side input of the subtractor 9 via an upper limiter 30. The output of the filter 8 and the output of the limiter 30 are subject to subtraction processing at the subtractor 9 and the subtraction output is fed to a voltage controlled oscillator 12. Thus, the control voltage of the voltage controlled oscillator 12 is controlled within a prescribed range and even when a video tape not recorded with the video signal is reproduced, the circuit is made stable in a short period of time.

Title: Ceramic bearing unit
Inventor: MOMOSE HIROTSUNE
IPC: F16C33/12
Filed: 1988-12-28
Abstract: PURPOSE:To support an axis to a specified position, which is subjected to thrust load and radial load by making up a bearing out of the inner race of a convexly curved surface in outer shape and of an outer race which has a concavely curved surface as an inner circumferential one, housing its inner race rotatably while its recessed surface is made to be a sliding one, and thereby firmly fixing a bearing unit via a mounting hole provided for a housing. CONSTITUTION:An inner races 1 is rotatably housed in an outer race 2, and the outer race 2 is firmly fixed onto a housing 3 so that it can not be rotated. A convexly curved surface 1a formed on the outer circumference of the inner race 1 comes mutually in contact with a concavely curved surface 2c formed on the inner circumferential surface so that a sliding surface is thereby formed. The resultant load F of thrust load Fs and radial load Fr is applied to a shaft B, being transmitted to the inner race 1 so that the projected surface 1a of the inner race 1 comes in contact with the recessed surface 2c of the outer race 2 so as to be slid at a position corresponding to the acting direction of the resultant load F. In this case, component force is developed owing to the resultant load F in the tangential direction of the recessed surface 2c, the component force acts in such a way that the inner race 1 is energized to the direction of an axial center 4 so that the race may be consistent with the axial center.

Title: Attachment structure for magnetic head
Inventor: KANEKO TAKUYA
IPC: G11B21/16
Filed: 1991-12-13
Abstract: PURPOSE:To secure the satisfactory attachment strength of a magnetic head by forming a bend part to a spacer to press the side face of a head arm. CONSTITUTION:A base end part of a spring arm 12 containing a magnetic head 11 at its tip part is fixed by the laser welding to a spacer 14 which is attached to a head arm 13 by calking. The spacer 14 includes a bend part 15 which presses at leas one of both side faces of the arm 13. In such a constitution, the part 15 of the spacer 14 presses the side face of the arm 13 in addition to the conventional calking. Thus the pressure of the spacer 14 can supplement the insufficient attachment strength of the head 11 due to an insufficient calking margin. Then the satisfactory attachment strength is secured for the head 11.

Title: Photometric apparatus
Inventor: OTSUKA HIROSHI
IPC: G03B7/099
Filed: 1992-12-09
Abstract: PURPOSE:To obtain a photometric apparatus which can measure the low luminance by logarithmically compressing/converting photo currents obtained by a photoelectric converting element and accumulating the currents in a capacitor. CONSTITUTION:When a MOS transistor Q1 is driven in an area where a sub threshold current flows, a photo current IP output from a photodiode (photoelectric conversion element) P1 becomes a logarithmically compressed current and accumulated in a capacitor C1. The load of the capacitor C1 is reset by a transistor Q4. A transistor Q3 performs the integral control of the capacitor C1. Accordingly, an integrated value of the photo current IP is logarithmically compressed to be a voltage VO at a connecting point between a source of a transistor Q2 and the capacitor C1. The dynamic range is made wide because of the logarithmic compression. Moreover, since the voltage accumulated in the capacitor C1 or photometric value is calculated, it becomes possible to measure the low luminance. A narrow spot can be measured with good accuracy.

Title: Airtight structure
Inventor: YOSHIDA RYOICHI
IPC: E04H3/14
Filed: 1994-12-01
Abstract: PURPOSE: To form an airtight structure into a reasonable shape as a pressure vessel, to ease construction, and to shorten the period for construction. CONSTITUTION: A low pressure room is provided with an airtight room 1, a lower part supporting body 3, which extends over leveling concrete 2, a curved construction part 4, which is curved and erected on the body 3 in the width direction so as to form the airtight room 1 and extended in the longitudinal direction, and a wall structure part 5 standing at both ends of the lower pressure room, so that the low pressure room is used as a low-pressure training room. The curved structure part 4 is formed by filling a gap between an inner plate 42 and an outer plate 43 with concrete 44. Since the principal part of the air- tight structure consists of curved ones, the shape of the structure is reasonable one as a pressure vessel. The lower supporting part is flat, giving good usability.  In addition, since both inner and outer plate bodies serve also as a form for the concrete, construction work can be completed easily and quickly.

Abstract: PURPOSE:To identify the equipment of a transferred frame sent from its own node while being circulated in a ring LAN without the revision of the frame itself by identifying a transfer frame between LANs and storing the destination of the transfer frame. CONSTITUTION:When a reception control section 34 detects a token, the reception control section 34 informs the acquisition of the token to an MPU 20 and the transmission right of a LAN II by a bridge 1 is acquired. The MPU 20 accumulates and stores the sender address SA of a transfer frame as an identifier (SA) of the transfer frame to a sender address management table 39. The transfer frame sent from the bridge 1 to the LAN II is fetched by a node 5, reaches the bridge 1 again while being circulated through the LAN II and is received by a frame receiver 33. The MPU 20 activates the sender address management table 39 to decide whether or not the sender address SA of the reception transfer frame is stored in the sender address management table 39 to eliminate the frame.
