IPC: G02B6/12
Filed: 1991-12-24
Abstract: PURPOSE:To provide a compact and low loss multi-branch waveguide device. CONSTITUTION:The multi-branch waveguide device is obtained by forming a Y-branch waveguide 4 and a slab waveguide 6 by the diffusion of metallic Ti. The waveguide 4 is provided wish a waveguide part 4a constituting an input port and waveguide parts 4b, 4c connected to the incident end face 6a of the waveguide 6. When signal light is made incident upon the part 4a, the signal light is branched by the waveguide 4 at the rate of 1 to 1. Two branched beams are made incident upon the waveguide 6 through a pair of waveguide parts 4b, 4c and the incident end part 6a. An inference pattern is formed in the waveguide 6 due to the two branched beams. Consequently bright and dark stripes are arranged on the projection end face 6b of the waveguide 6 at a prescribed interval to divide the signal light into 16 parts.

Title: Impulse hammer apparatus
Inventor: ARAKAWA MASAO
IPC: G01M7/08
Filed: 1996-12-24
Abstract: PROBLEM TO BE SOLVED: To obtain an impulse hammer apparatus by which an always precise constant impact force is given to an object to be measured and by which the transfer function of a vibration system can be identified with high accuracy by a method wherein an elastic support means is arranged in the central part of the shaft of a hammer and a step cam of a rotation adjustment type is arranged at the base end of the shaft. SOLUTION: An impulse hammer apparatus is set in such a way that the head of a hammer 1 hits a prescribed place at a model 2 when the head is swung. Then, when a step cam 9 of a rotation adjustment type is operated, a shaft 8 is moved around a leaf spring 10 (an elastic support means) by the step cam 9. That is to say, the head of the hammer 1 is moved to a direction separated from the model 2 against the elasticity of the leaf spring 10. Then, the base end of the shaft 8 becomes free in a step part (a) at the step cam 9, the hammer 1 is swung due to the restoring force of the leaf spring 10, and the model 2 is hit at a prescribed impact force. After that, when the step cam 9 is turned, the head of the hammer 1 is separated again. In this manner, the model 2 can be hit at an always precise constant impact force.  In addition, the cycle of a hammering operation is adjusted to a prescribed value due to the rotation of the step cam 9.

Title: Tv frequency band radio wave absorbent body
Inventor: YAMAMOTO TAKESHI
IPC: H01Q17/00
Filed: 1989-12-29
Abstract: PURPOSE:To enable an absorbent body to be easily provided and to absorb a TV frequency band radiowave of wide band by a method wherein the imaginary number component peak value of the complex magnetic permeability of a molded body, whose main material is composed of a binder and magnetic particles which are in a specified dry weight ratio, is so set as to be lower than a TV frequency band. CONSTITUTION:A binder and magnetic particles or a binder, magnetic particles, and carbon fiber are used as main materials, and the main components are set to be in the mixing ratio by dry weight 5-25% of binder: 75-95% of magnetic particles. If the magnetic particles are above 95% by weight, a molded body is hard to set, and if below 75%, the molded body is inferior in intrinsic performance. The reason why magnetic particles are set high in compounding ratio is that an imaginary number component mu'' of a magnetic permeability is enhanced and a real number component mum'/mum'' of a magnetic permeability is set small in value. By this setup, a large molded body can be easily formed, so that a radiowave absorbent body of this design can be prevented from deteriorating in radiowave absorbing property due to the gap between panels.

Title: Digital camera
Inventor: YAMAMOTO SHIGEAKI
IPC: H04N5/225
Filed: 1999-12-02
Abstract: PROBLEM TO BE SOLVED: To suitably output a through image from a monitor even during the time of charging by stabilizing a clock. SOLUTION: When a strobe 42 is charged, the frequency of a system clock outputted from a clock generator 40 is reduced from 30 MHz to 15 MHz. The lowest warranty voltage that the system clock of 15 MHz is outputted stably is lower than the lowest warranty voltage that the system clock of 30 MHz is outputted stably. Thereby, even when the battery voltage is lowered suddenly during the time of charging of the strobe 42, the clock is outputted stably. Thus, through image processing is performed suitably even during the time of charging.

Then all the peripheral devices 5 to 7 are arbitrated, to decide a peripheral device to acquire the right to use the bus. The peripheral device having obtained the right transfers instructions or data. Other peripheral devices must decode and accept the instructions or data. If they are in an acceptable state instructions or data are processed, but if they are state which cannot be accepted, NACK is sent in the next bus cycle.
