Title: Laser device
Inventor: WAKATA HITOSHI
IPC: H01S3/137
Filed: 1990-02-21
Abstract: PURPOSE:To enable the high-accuracy adjustment of a wave-length which permits etalon to transmit by projecting a light from a light source into the etalon and controlling a wavelength which permits the etalon to transmit based on a strength of a reflected light from a reflecting plane of the etalon. CONSTITUTION:A part of a laser beam 29a from an He-Ne laser 26 which has transmitted through a beam splitter 27 passes through a total reflecting mirror 3 and enters into a etalon for rough adjustment 5, and then it is reflected by a reflecting plane of the etalon. Then, an intensity of the reflected light is detected by a light sensor 30. Meanwhile, a part of laser beam 29b which has been splitted by the splitter 27 is irradiated with the etalon 5 and is reflected by its reflecting plane. An intensity of that reflected light is detected by a light sensor 30b. The outputs of the sensors 30a and 30b are introduced to a control mechanism 31 and a gap length of the etalon 5 or its angle to a beam 7 are modulated so as to make an output difference between the sensors 30a and 30b zero. As a result, the center transmission wavelength of the etalon 5 becomes a predetermined wavelength.

Title: Measurement of local displacement
Inventor: TAGUCHI YASUYO
IPC: G01B21/00
Filed: 1988-02-26
Abstract: PURPOSE:To measure a minute local displacement accurately, by bringing a displacement sensor in which a number of sensor contacts are arranged at a fixed interval with two conductor points of a test object to judge conductivity between the test object the sensor contact. CONSTITUTION:In a displacement sensor 2, a number of sensor contacts 6a-6n each with a fixed contact width h2 are arranged on one surface of an insulator base 5 linearly at a fine fixed interval. On the other hand, the width h1 of conductor points 3a and 3b is slightly larger than the contact width h2. Since sensor contacts 6i and 6j can be identified according to a distance l between the conductor points 3a and 3b by measuring an electric resistance between a test object contact 8 and the sensor contacts 6a-6n, the distance l between the conductor points 3a and 3b of the test object 1 can be determined. Here, when a local displacement DELTAl occurs between the conductor points 3a-3b, sensor contacts corresponding to the conductor points 3a and 3b are shifted to 6i and 6j+1. Thus, the local displacement DELTAl can be determined by identifying the sensor contacts 6i and 6j+1.

Title: Communication equipment
Inventor: NAKAMURA MITSUHIRO
IPC: H04N1/44
Filed: 1994-03-14
Abstract: PURPOSE:To select whether immediately outputting a document to be handled by cipher communication or not by selecting either an immediate output function or a confidential output function making possible arbitrary outputting. CONSTITUTION:When it is decided that a key corresponding to a designated key number is not registered, a display part displays a key error and while observing the picture, a user conducts the key operations of an operation part 6. When the erasure of received data is judged, the data are cleared and processing is returned later. When it is desired to leave the received data remaining according to the will of the user or when the immediate output is not selected at the time of confidential box registration, the received data are automatically stored in a confidential box 5 without being made into plane sentences. In this case, when an operation is conducted to output the content of the confidential box 5, a control part 1 recognizes the confidential output, decides whether any cryptographic key is registered or not and decides whether that cryptographic key is matched or not and when it is matched, the data are outputted by a printer part.

Title: Floating decimal-point addition/subtraction device
Inventor: NAKANO HIROSHI
IPC: G06F7/485
Filed: 1990-02-22
Abstract: PURPOSE:To increase the rounding processing speed in this floating decimal-point addition/subtraction device by predicting an OR from the mantissa parts of a number to be computed and an operand instead of securing the ORs of all bits lower in order than a rounding bit without having any reliance on the bit width of a computing element. CONSTITUTION:The row zero detecting circuits 8 and 9 detect the bit length having countinuous 0 from the lowest-order bits to the mantissa parts outputted from a register 3 for the number to be computed and an operand register 4. Then the mantissa part corresponding to the smaller exponent is shifted to the right so as to allow the bit length of the mantissa corresponding to the smaller exponent to be matched with an exponent. When the bit length having continuous 0 is smaller than the bit length which is lost at the right shift of the mantissa, the value is equal to 1. Otherwise the value is equal to 0. For this purpose, the spilt bits are used. Thus it is possible to predict the ORs of all bits lower in order than a rounding bit and to increase the rounding processing speed when an operation is carried out with the spilt bits added to the ranks lower than the rounding bit.
