Title: Light wavelength converter
Inventor: TAKESHIGE KUNIHIKO
IPC: G02F1/37
Filed: 1990-11-30
Abstract: PURPOSE:To produce a polarization inversion area having enough depth to the depth of waveguide by inversing the polarization direction of the surface of a substrate having optical waveguides by the second-order period and making the width of the inversion area 3/4 of the period. CONSTITUTION:LiNbO3 is used for a substrate 1, on which SiO2 is deposited and a striped pattern is formed to have the second order period and the width 3/4 of the period. By subjecting this substrate 1 to heat treatment near the Curie temp., an area 3 in which polarization is inversed is formed just under the SiO2. Then the SiO2 is removed and three-dimensional optical waveguides are formed perpendicular to this striped pattern to complete production of the optical wavelength converter. The depth of the polarization inversion area 3 depends on the width x of this area. Thereby, the obtd. polarization inversion area has enough depth and gives an output about 2.3 times as the output from an element having the third order period. Thus, the obtd. wavelength converter has high efficiency.

Title: Signing and authenticating system
Inventor: NISHIOKA GENJI
IPC: H04L9/10
Filed: 1992-12-18
Abstract: PURPOSE:To shorten and accelerate time required for a calculation processing and to improve safety by placing a cryptological assumption on a discrete logarithm problem on a link and reducing the frequency of power raising calculation required for a signing or authenticating processing. CONSTITUTION:In the signing processing, a signature (x) for a document (m) is prepared from one's own secret information by using a signing person side device 200 and information (m, x) is sent through a communication channel 400 to a confirming person side device 300. A confirming person checks the propriety of the received signature and confirms the propriety of the received document (m) at the confirming person side device 300 by using the open information of a certifying person. In this case, the signing person prepares the signature (x) for satisfying the function of x<4>-4f(m)x<2>+4nu=0 (mod N) obtained by using one-directional hash function (f) or x<4>-4mx<2>+4nu=0(mod N) for positive constants nu and N which are the open information of the signing person. Thus, since the frequency of the power raising calculation is less, signing and authenticating can be efficiently performed.

Title: Camera using film provided with magnetic storage part
Inventor: TAMAMURA HIDEO
IPC: G11B15/10
Filed: 1989-12-28
Abstract: PURPOSE:To make automatic loading normal and to prevent a magnetic head from being abraded and a film surface from being damaged by providing a head retreat means and keeping the film surface and the magnetic head from coming into contact with each other at the time other than the time of writing or reading out information. CONSTITUTION:When an automatic loading(AL) action is started, a head bottom plate 1 and a presser bottom plate 12 are retreated in a direction that they separate from a film 56. When an exposing action is finished, the head bottom plate 1 and the presser bottom plate 12 move, so that the magnetic head 10 is brought into contact with the magnetic storage part of the film 56, and rollers 3 and 5, 14 and 16 are pressed to the surface of the film 56 so as not to sag the film 56 with specified force, then the magnetic head 10 is driven through a magnetic recording circuit 109 to write the desired information in the magnetic storage part. In the case of detecting that the winding of one frame is finished, thereafter, the head bottom plate 1 and the presser bottom plate 12 are restored. Thus, such a trouble that the automatic loading is not normally performed, that the magnetic head is abraded or that the film surface is damaged by the magnetic head is prevented.

Title: Circuit breaker
Inventor: KAMINO SHUNEI
IPC: H01H71/10
Filed: 1990-11-30
Abstract: PURPOSE:To instantaneously open a circuit against overcurrent and also automatically restore a linkage mechanism after heating into a state whereby the action of reclosing the circuit is possible by providing a linkage mechanism between a means for closing and opening the path between fixed contacts and an electromagnet for forcibly opening contacts during shortcircuit, and providing the linkage mechanism with functions of self retention and self restoration. CONSTITUTION:When a large current is generated in a main current path an electromagnet 30 for forcibly opening contacts during shortcircuit is instantaneously put in action to push a switching control lever 17 downward via a projecting bar 31 and a linkage mechanism so as to release a fixed contact 10 and a moveable contact 8. When the main current path is shut off the electromagnet 30 for forcibly opening contacts during shortcircuit is demagnetized and the projecting bar 31 returns to its upward position. In this case, the linkage mechanism keeps its position by itself while the contacts are released. When the switching control lever 17 is pushed down by a spring release mechanism which is actuated by the action of an overcurrent reacting device which has detected an overcurrent, a lever 113 is released into a powerless state so that the linkage mechanism is restored.

Title: Mass flowmeter
Inventor: YUUSHIFU EE FUSEIN
IPC: G01F1/84
Filed: 1992-12-18
Abstract: PURPOSE: To enhance measurement results by a method wherein a Coriolis pipe is loaded by at least one reinforcing spring which increases strength for an excitation mode. CONSTITUTION: A Coriolis pipe 1 is arranged in a compensation cylinder 5. The pipe 1 is loaded by a reinforcing spring 6 which increases strength for an excitation mode. This spring 6 is engaged with a center part of the pipe 1. This is because strength for the excitation mode of the pipe 1 is increased so that strength for a Coriolis mode of the pipe 1 is not influenced. Thereby, the vibration number of vibration of the pipe 1 in the excitation mode is sufficiently definitely distant from the undesired vibration, in short the vibration number of vibration which becomes a barrier, and influences of this type of barrier vibration are suppressed.

Title: Single mode ultrasonic wave generation and object thickness measurement utilizing the same
Inventor: YAMANAKA ICHIJI
IPC: G01B17/02
Filed: 1990-11-30
Abstract: PURPOSE:To selectively generate a desired mode ultrasonic wave with high efficiency by irradiating an energy beam focused to the wavelength of a desired mode ultrasonic wave to an object and scanning it at a speed equal to a phase speed. CONSTITUTION:When a pulse beam from a laser 1 is focused by a collimeter 2 into a rectangular form and radiated to the surface of an object 5 through a beam deflector 3 and a lens 4, the laser 1 is triggered in accordance with a synchronous signal from the deflector 3 and a laser pulse which travels on the object 5 at a high speed is obtained. If a rotational polyhedron is used as the deflector 3, the sweep rate of the beam on the object 5 can be controlled by the change of the rotating speed to a value approximate to the phase speed of a desired mode ultrasonic wave. The beam width can be controlled by the change of the focus distance of the lens 4 or a distance from the object 5 to an appropriate value. It is thus possible to determine the frequency of a ultrasonic wave generated and measure the thickness of the object from a relationship between the frequency and the phase speed.

Abstract: PURPOSE:To normally control a motor by determining arrival of a motor rotating speed at a steady range when a difference between maximum data and minimum data of data of plurality of times calculated at each predetermined timing stored in a storage means is a predetermined value or less. CONSTITUTION:When data regarding the rotating speed of a motor 10 is calculated at a predetermined timing, data of past predetermined times stored already in a storage means of a controller 14 are sequentially shifted by one, and data calculated this time is stored in a latest data storage area. Then, when data corresponding to a center of large and small values of data of past predetermined times stored in the storage means for storing latest data is determined to fall within predetermined range, a difference between the maximum data and the minimum data of the data of the predetermined number of times stored in the storage means is calculated. If the difference is a predetermined value or less, it is decided that the speed of the motor 10 arrives at the steady range.
