Title: Wire rod alignment device
Inventor: KAWASAKI SEIJI
IPC: B65G65/44
Filed: 1987-02-21
Abstract: PURPOSE:To align wire rods one by one toward the predetermined direction in a condition free from overlapping and entanglement by providing a direction alignment means at the last end of an alignment face. CONSTITUTION:Wire rods 2 discharged aslant from a hopper 4, overlapped and entangled with each other, are temporarily separated into independent pieces in the course of sliding down along the first and second guide plates 9 and 10. Then, the wire rods 2 while being lowered onto the alignment face 11A of an alignment unit proper 11, are aligned into a single layer free from entanglement via plate springs 17 and 17A. Furthermore, a balance between an air jet propulsion force from an air jet nozzle 22 and the weight of the wire rods 2 are used to align forcibly the wire rods 2 in a proper direction at the last end of the alignment face 11A, and each rod is separately arrayed toward the predetermined direction for transfer to a feed part. According to the aforesaid constitution, wire rods of small diameter and large length can be aligned so properly as to be free from overlapping, entanglement and irregular direction.

Title: Expanded communication system
Inventor: KAMATA HIROSHI
IPC: H04W56/00
Filed: 1991-03-05
Abstract: PURPOSE:To reduce the time by inserting a specific code of a master set to a radio line connection request data and sending the resulting data. CONSTITUTION:When a slave set 1 sends a data in a radio wave from a district where reception areas of master sets D1, B2 are overlapped, the data is sent to the master sets D1, B2. Although the master set reads a header of a reception data and is going to connect the master set and a line according to a master set call code sent in a radio wave from the slave set 1, when the master set call code is a call code of a master set C, since the radio line with the master sets D1, B2 is not connected, the slave set 1 changes the master set call code into a call code of a master set D and sends the code in a radio wave and the code is sent simultaneously to the master sets D1, B2, then the header is read to stop the line connection with the master set B2 and only the master set D1 corresponding to the master set call code is connected to the radio line with the slave set 1 for the data communication. Thus, the radio line connection time is reduced.

Abstract: PROBLEM TO BE SOLVED: To enhance the rigidity of a shaft part of a racket frame and to improve a swinging-through property by embedding a metallic pipe or strip-like reinforcing plate into at least the shaft part and mounting a weight member having a specific gravity higher than the specific gravity of a fiber reinforced resin at a face part. SOLUTION: The tube 1A of the racket frame for tennis consists of the face part 1a, the shaft part 1c and a grip part 1d. After a prepreg is disposed on the outer periphery of the tube 1A, the reinforcing plate 5 made of a βtitanium alloy is so disposed as to extend from the flank at the top end of the grip part 1d through the shaft part 1c to the rear end of the face part 1a. The reinforcing plate 5 is further covered by the prepreg and then the tube 1A is expanded and heated in a metal mold to cure the prepreg. The prepreg is subjected to deflashing after parting from the mold, by which a racket frame product is obtained. As a result, adequate strength and rigidity are imparted to the racket frame and the durability to repetitive fatigue is improved.

Title: Discrete time type controller
Inventor: YOSHIKAWA NORIO
IPC: G05B21/02
Filed: 1986-02-26
Abstract: PURPOSE:To prevent the overshoot due to the over-integration and to omit the need to set again the anti-reset value by setting the ratio between the gain of a controlled system model obtained by estimation of a parameter and the set value at the initial integration value of the deviation of the PID control in a steady state. CONSTITUTION:The parameter of a controlled system model is estimated for each sampling interval based on the data on both manipulated variable and controlled variable and replaced by a parameter estimating means. Then the ratio between the controlled system gain obtained by said parameter estimating means and the set value is set at the initial integration value of the deviation of the PID control or its similar control algorithm when the deviation between the controlled variable and the set value is less than a prescribed level. In other words, a discrete time type controller 2 supplies the controlled variable continuously to a controlled system 1 through a sampler 3 samples the controlled variable after A/D conversion and supplies the output of a PID/ASC (adaptive switching control) controller 4 which calculates the manipulated variable by a prescribed algorithm based on the deviation from the target set value to the controlled system 1 via a holder 5 which holds the output of the controller 4 for a sampling period after D/A conversion.

When it is required to deodorize the composted product, a porous material (e.g. an artificial carbonization product) is used. The media having various kinds of shapes such as a cross shape and a spherical shape can be used. The four side surfaces and bottom surface of the composting tank shown in the figure are surrounded with concrete walls 1, and a longitudinally transferable stirrer 2 is disposed on the upper surface to till the raw material to be composted. The media 6 for promoting the oxidation and the decomposition are dispersed and mixed in an amount of >=20vol.%. Air-releasing nozzles 5 are disposed on an air-charging pipe 4, and the raw material is brought into contact with and oxidized with air or oxygen. A weight-selecting machine, etc., is used for removing the media for promoting the oxidation and the degradation.

Abstract: PURPOSE:To obtain a PV element array characterized by few cross talks, by forming island-shaped, low carrier concentration region on the surface of a high carrier concentration substrate of HgCdTe, forming diodes therein, and providing a P<+> region between the diodes. CONSTITUTION:An HgCdTe substrate 11 and Hg are heat-treated in an ampul, and P<+> type is obtained. An insulating film 12 is deposited on the substrate 11, and opening regions 13 are formed. The device is heat-treated together with Hg in the ampul, and P-type regions 14 are formed. After the insulating film 12 is removed, a resist layer 16 and an Al film 17 are formed on each diode forming region 15. After patterning intense light is projected, and high- impurity P<+> type layers 18 are form. Impurities are implanted in the region 15, and N<+> layers 19 are formed. Since the diffusion length of carriers 20a, which are generated by incident infrared light hnu between the diodes is short, the carriers do not contribute to a signal. Of the carriers generated beneath the diode, the carriers 20b, which are diffused toward the neighboring diode, are recombined in the region 11. Therefore cross-talk is not generated.

Filed: 1983-03-10
Abstract: PURPOSE:To enable a high-speed measurement of spatial distribution of equivalent non-linear parameter for ultrasonic medium with a simple construction by deconvoluting phase information obtained from the demodulated received signals. CONSTITUTION:The sum of the time (x1/C0) until a pumping wave reaches the position of a wave to be measured from the transmission of the pumping wave and the time (z1/C0) required until the wave being measured first reaches a vibrator XB from the phase modulation thereof with the pumping wave is represented by t1. An output VR of a receiving amplifier 7 begins to undergo a phase modulation in time t1 from the transmission of the pumping wave and a phase modulated output is produced continuously for the time t2=z2/C0 during which the wave being measured phase modulated by the pumping wave has passed by the section to be measured. A phase detector 8 compares output of an oscillator 2 with VR in the phase and the phase of VR is outputted as function of time phi(t), hence as function of the coordinate (z). The output is inputted into a filter 9 and thus, an equivalent non-linear parameter (B/A)l is obtained as function (B/A)(t) of time.
