Title: Forming device for optical waveguide type diffraction grating
Inventor: INOUE SUSUMU
IPC: G02B6/12
Filed: 1995-04-17
Abstract: PURPOSE: To provide an optical waveguide type diffraction grating forming device capable of forming a grating of a desired grating interval with a simple constitution. CONSTITUTION: An optical fiber 1 is the optical fiber having a Ge added core and the refractive index of a part irradiated with a laser beam whose wavelength is near a wavelength 240nm can be raised. The laser beam generated from a pulsive laser light source 4 is made to be a slit-shape through an optical system 5 to be projected on the core of the optical fiber 1. However the optical fiber 1 is moved by an automatic stage 2, output pulses corresponding to the moving amount are applied to a frequency divider part 6 by a linear encoder 3. The laser beam is projected on the fiber 1 by allowing the frequency divider part 6 to output an output signal according to the value set in a frequency dividing ratio setting part 8 and by making a laser driving part 7 operate intermittently.  Thus, the part having a large refractive index can be partially formed, and a Bragg diffraction grating can be formed.

Inventor: KARASAKI TOMIO
IPC: G01N21/59
Filed: 1980-07-04
Abstract: PURPOSE:To enable the detection of the spacing of the samples in the electrophoresis pattern by obtaining the data outside the fixed range of density fluctuation, even if there are discrepancies between the samples or differences of electrophoresis movements, after providing an optical slit at the center line of the first sample. CONSTITUTION:The point P where the density is the highest is searched by scanning along the center line of the first sample A of the multitest samples. Then the sample carrier is moved toward the X-axis and it is stopped at the middle point R between the samples B and C. Central point S of the sample B is obtained by determining the density fluctuation of sample (maximum and minimum points) and the difference of the maximum and minimum values (amount of variation) is obtained after discarding the values of excessive fluctuation, and then the range of sample B is determined from the data under the fixed value and it is made the middle point. The overall density of sample B can be measured by returning the sample carrier to the central point S and then to the starting point O along the Y-axis. When the sample is shifted toward the Y-axis, the measurement can be performed by using another slit with its opening along the Y-axis.

Title: Radio communication equipment with small power
Inventor: YOKOTA TAKAHIRO
IPC: H04W84/12
Filed: 1987-04-14
Abstract: PURPOSE:To remarkably contrive the reduction of the power consumption during the operation of a small power radio communication equipment by using a 1st detection signal from a 1st detector so as to operate a bit synchronization comparator of a signal processing section and using the 2nd detection signal of a 2nd detector to operate a discrimination code comparator. CONSTITUTION:In receiving a carrier signal lower than a 1st level L by a receiver 3, neither the signal processing of the received data nor transmission is executed and in receiving a carrier signal higher than the 1st level L but lower than a 2nd level H by the receiver 3, a transmitter 4 is not started. Then the 1st detection signal CS-L of a 1st detector 31A starts only a bit synchroniza tion comparator 62A to decide the propriety of the bit synchronization clock of the demodulated data, and when it is decided to be correct, the processing is finished at that time, and when it is decided to be incorrect, the data is stored as a disturbing wave. Since a signal processing section 6 applies no signal processing to discriminate its own station, the power consumption of the receiver is reduced.

Abstract: PURPOSE:To simplify information processing by a control means by distributing the drive force of an engine in case where signal values from a front wheel revolution sensor and a rear wheel revolution sensor are different from each other and/or where signal values from a front side buffer sensor and a rear side buffer sensor are different from each other. CONSTITUTION:Only front wheels 10 of a all-wheel drive vehicle 2 are in driven status when the vehicle 2 is in a basic status, such as running at a constant speed. When different signal values are received from a front side buffer sensor 42 and a rear side buffer sensor 46, a control means 32 outputs a control current corresponding to the input difference to an oil pressure unit 30, thus a wet-type multiple disc clutch 24 is operated to connect an output shaft 18 to a rear side drive shaft 28, thus resulting in four-wheel drive. In this case, the torque ratio between the side of the front wheels 10 and the side of rear wheels 16 is adjusted to 100:0 to 50:50 according to the input difference. When a front wheel revolution sensor 34 and a rear wheel revolution sensor 38 produce difference rpm signal values, the torque ratio between the side of the front wheels 10 and the side of the rear wheels 16 is adjusted to 100:0 to 50:50 according to the difference in rotational speed in the similar way.
