Title: Optical pickup device
Inventor: KATAYAMA HIROSHI
IPC: G11B7/135
Filed: 1990-08-31
Abstract: PURPOSE:To detect the position of an objective lens with a high S/N by forming a light source as an element having an elliptical far-field pattern and making the short diameter direction of a beam spot projected from the light source onto a photodetector coincident with the radial direction of the objective lens. CONSTITUTION:For the light source constituting an objective lens position detecting means 21', a semiconductor laser 8' having the elliptical far-field pattern is used and the short diameter direction of the far-field pattern of this semiconductor laser 8' is made coincident with the radial direction of an objec tive lens 1. In this case, since the diameter of a beam spot 10 in the radial direction for detecting the maximum eccentric amount is narrowed down in comparison with the case due to a conventional optical pickup device, sensitivity is improved for detecting the position of the objective lens in the radial direc tion. Thus, the position of the objective lens can be detected with the high S/N both in a focus direction and in the radial direction.

Title: Method of producing polyamide fiber
Inventor: SATOU TAKUJI
IPC: B65H54/02
Filed: 1983-12-08
Abstract: PURPOSE:To prevent a package from variation of take-up tension according to the take-up position in a spindle drive take-up machine by traversing a spindle itself to which a bobbin is attached according to the take-up speed. CONSTITUTION:Polyamide fiber Y from a spun yarn mouth piece is intercepted and processed by an air interception nozzle 4 and hot stretched through a yarn path guide 8 by goddy rollers 5, 6 to be taken up into the form of barn with 4,000m/min or more speed through a yarn path guide 8 by a take-up unit 9 performing traverse motion. A drive motor 10 of this take-up unit 9 is controlled to give a constant take-up tension by a control board 13 consisting of a tension detector 7, a power controller 11 and a strength setter 12. And a package 15 itself is traversed by a hydraulic cylinder 14 such that the take-up speed V and traverse speed T have the following relationship; V/4,000<=T<=V/300. Thus, the yarn is not traversed and the take-up tension is not varied with the winding position of package so that phe uniform package can be obtained.

Title: Phase modulation receiver
Inventor: ONO HIROYUKI
IPC: H04L27/22
Filed: 1992-08-31
Abstract: PURPOSE:To prevent deterioration in C/N versus BER by providing a channel replacement switch and an inversion non-discrimination switch inverting a phase vector on the receiver to attain transmission of phase modulation signal without differential conversion. CONSTITUTION:All combinations among channel states of demodulated signals and phase vector states of a recovered reference carrier to be taken are inputted to a frame synchronization circuit 10 under the control of a control circuit 11 with a channel replacement switch 8 and an inversion/noninversion switch 9. The frame synchronization circuit 10 establishes frame synchronization depending on the inputted combination and sends a frame asynchronization alarm signal to the control circuit 11 in the case of asynchronization. Even when the state is asynchronous even after a series of combinations are finished, a frequency of a receiver side local oscillator is changed by one stage. The operation as above is repeated to seek the establishing point of frame synchronization.

Title: Camera and photograph printer
Inventor: TERASHITA TAKAAKI
IPC: G03B17/24
Filed: 1989-09-07
Abstract: PURPOSE:To realize a camera and a photograph printer, both of which ensure an unexposure part where photographing information is recorded for each film frame by using a current film, and recording a photographing frame with a size which is slightly smaller than the current frame. CONSTITUTION:In a photographing lens 10, the angle of photographic view is set smaller than that of an ordinary camera. A recording position on the photographic frame 20 of a photographic film 9 is deviated to the upper side from the current position; therefore, a photographing information recording area 22, in which a photographing information bar code 21 is recorded, is formed below the photographing frame 20. At the time of photographing, photographing information is inputted to a bar code signal generating circuit 32 after it is encoded by a photographing information inputting part 30 through manual operation or automatic decision. The bar code signal generating circuit 32 converts a code signal into a bar code pattern signal, and sends it to a driver 33. Interlocked with a shutter mechanism 12, the driver 33 drives a bar code recorder 35 to record the photographing information in the recording area 22, which is the unexposure part of the film 9, as the bar code 21.

Accordingly, the quarried stone can be easily formed into a shape of the natural garden stone.

Title: Load estimating method
Inventor: MOTOHASHI JUN
IPC: H02J3/00
Filed: 1998-08-19
Abstract: PROBLEM TO BE SOLVED: To prevent erroneous recognition, when attention is paid to a current balance of load and estimate with higher accuracy that a connected load is a three-phase induction motor without being effected by the changed voltage balance. SOLUTION: When a three-phase load 10 is connected to a three-phase three- wire type power distribution line, a personal computer calculates the ratio |Z1/Z2| of the positive phase/reverse phase impedance of a load. When such a ratio satisfies the estimated condition (10>=|Z1/Z2|>=4), it is estimated that the load 10 is a three-phase induction motor. Moreover, it is an additional estimation condition that the ratio |Z1/Z2| not change for the specified period.

In addition, a scraping plate 5 is provided on the inner surface of the contact adjustment ring 3. This construction is, for example, such that small blade pieces are partially stacked over the other like a camera stop to/form a through hole 6 in the center.

After checkup operation, the through hole 6 is narrowed and a hole edge part scrapes an attachment off the thermal needle 2, if the thermal needle 2 leaves the object. A heat cracking gas is sent to an HCl detector.

Title: Cover plate for range
Inventor: TAKUBO YOSHIICHI
IPC: F24C15/12
Filed: 1998-08-20
Abstract: PROBLEM TO BE SOLVED: To open/close a plurality of cover plates provided for respective burners of a range independently by securing each cover plate to the top plate of the range through a fixing means. SOLUTION: Two burners 13, 13 are arranged on the upper surface of the housing 11 of a range housing an oven 12 and a top plate 2 is applied to housing 11. A cover plate 4 having a square top plate 41 surrounded by a circumferential wall 42 is provided, at the left and right rear ends thereof, with fixing metals 6 and, at the left and right front ends thereof, with corner metals 5. A leg for keeping horizontal attitude of the cover plate 4 is projecting from the lower surface of the corner metal 5. Since two cover plates 4, 4 provided, respectively, with the fixing metals 6 are secured to the range A while being arranged in parallel, cover plates 4, 4 can be opened/closed independently and used independently and simultaneously as a shield plate 43 and a mounting plate 44.  Upper surface of the range can thereby be used effectively as a shield plate 43 when one burner 13 is used and as a mounting plate 44 the other burner 13 is not used.

Title: X-ray detector
Inventor: KUROJI HARUO
IPC: A61B6/03
Filed: 1983-12-12
Abstract: PURPOSE:To heighten X-ray utilization efficiency and improve sensitivity by arranging a spacer made of a highly insulating material having little X-ray absorption between front edges of an anode plate and a cathode plate and an X-ray incident window. CONSTITUTION:A spacer 40 is formed of a highly insulating material having little X-ray absorption while being arranged between an electrode array and an incident window 3 so as to fully cover at least the front of the electrode array. Thereby, the gaseous part is excluded between the electrode plate front edge and the rear face of the incident window, thus generating no damping of X-rays 5 due to the gas at this part, while generating slight damping thereof only at the spacer 40 and the X-rays are incident into an electrode plate separation chamber. Further, when rubber or the like, which is relatively soft and flexible, is used as the spacer, it contributes to prevent vibration of the electrode plates, thus checking a microphonic noise. Thereby, X-ray utilization efficiency can be heightened, while improving sensitivity.
