Patent JP-H0332120-A (JP)
Title: Radio repeater
Inventor: SUZUKI MASAHIRO
IPC: H04B7/212
Filed: 1989-06-28
Abstract: PURPOSE:To adjust the time axis between a slave station and a relay station without intervention of a master station by providing a transmission timing designation means designating the information at which talking channel the time axis is to be adjusted to the slave station. CONSTITUTION:A timing designation circuit 20 at a relay station 50 designates the information at which talking channel of a radio line the time axis is to be adjusted to the slave station. When the time axis code is sent from a slave station 60 through the said talking channel in response to the designation, a time axis code detection circuit 12 detects the time axis code and a time axis difference detection circuit 14 detects a difference between the time axis of the slave station 60 and the time axis of its own relay station. Then when a discrimination circuit 26 discriminates it that the connection of a radio line is not made between the its own relay station and the master station 40, the circuit 26 sends a data relating to the difference of the time axes detected by a transmitter 10 to the slave station 60. Thus, even when the radio line between the relay station 50 and the master station 40 is not interconnected, the time axis between the slave station 60 and the relay station 50 is adjusted.

Filed: 1979-12-20
Abstract: PURPOSE: To decrease the flaws of a magnetic disc by making the displacing direction of a head support and the displacing direction of a blocking part same, slowly releasing the blocking of the head support and allowing the magnetic head to contact with the disc or detach therefrom at a low speed.  
     CONSTITUTION: When a plunger solenoid 15 is energized, a plunger 2 is attracted. In this case, the plunger 2 is slowly attracted by the air damper effect of a tyrelike damper 27. Therefore, the head 2 allows to contact with a flexible disc 1 at a low speed. When the solenoid 15 is deenergized, air is gradually sucked into the air chamber of the compressively deformed damper 27, and said damper 27 gradually restores the original shape. Therefore, air damper effect is created and the plunger 22 slowly resets. In this way, the contacting and detaching of the head 2 with and from the disc 1 are accomplished slowly by the damper effect of the tyrelike damper, the flaws produced in the disc 1 are decreased.

Title: Control device for rolling mill
Inventor: MARUYAMA AKIO
IPC: B21B37/00
Filed: 1989-06-30
Abstract: PURPOSE:To control rolling mills with high accuracy by selecting an optimization standard according to the conditions for working a base material for rolling, determining the controlling variables to be supplied to respective control sections from the distribution ratios of the controlling variable corresponding to this optimization standard and controlling the respective control sections, such as roll speed, by this controlling variable. CONSTITUTION:Only one optimization standard is selected from the respective optimization standard flows when the data on the working conditions is applied to an optimization standard selecting section 1. If, for example, the data on the working conditions of a high carbon content of the base material is applied, the hardness of the base material is high and, therefore, the power horse distributions between respective rolling stands are preferably optimized and this optimization standard flow 2 is selected. The distribution ratios of the controlling variables to be applied to the control sections of the respective stands to optimize the horse powers to be applied to the respective rolling stands are stored in a distribution ratio memory section 3. A controlling variable computing section 4 reads the distribution ratios of the controlling variables from the memory section 3, substituted the same into a prescribed mathematical model and determines the controlling variables to be supplied to the control sections of the respective stands. The computation of the high accuracy is possible in this way and the rolling quantity is improved.

Title: Scraper device for belt conveyor
Inventor: NOBUNAGA HIROSHI
IPC: B65G45/12
Filed: 1987-07-06
Abstract: PURPOSE:To enable the change in the contacting angle of the edge of a scraper due to the expansion and contraction of a belt to be reduced by applying a deflecting force to a parallel crank mechanism forming a parallelogram by means of a deflecting force providing means, so that the edge can be abutted on the return course of the belt conveyor. CONSTITUTION:Receiving the spring deflecting force of a spring member 24, an edge 22 is abutted on the return course 18b of a belt conveyor to exert a shearing force, thus the adhered substance on the return course 18b hits the edge 22 and is scraped down from the return course 18b. Next, the belt conveyor expands or contracts due to the variation in the amount of material having been thrown on the forward course 18a so as to be conveyed, and the variation in the tension having been given to the belt conveyor 18, or the like. However, since a spring deflecting force is exerted toward the belt 18, the edge 22 of a scraper device 10 follows up with the expansion and contraction of the belt 18, and oscillates together with a connecting link 28, so that the abutment with the belt 18 can be maintained. Even if the belt 18 is elongated by use extending over a long period of time, the abutment of the edge 22 on the belt 18 can be maintained in the same manner.

Title: Integrated semiconductor laser
Inventor: OSAWA JUN
IPC: H01S5/00
Filed: 1985-07-31
Abstract: PURPOSE:To reduce an operating current by forming a crest-shaped gain distribution by a crest-shaped current distribution which is maximized on a central waveguide in a current distribution, and increasing the mode gain for a basic array mode to become higher than the array mode of higher order. CONSTITUTION:A current blocking layer 21 having a striped separator 22 of narrower width than the width of the entirety with a center line at the center of the array made of P<+> type InP. Since a P-N junction between an N-type InP power clad layer 2 and the P<+> type InP layer 21 is reversely biased, a current flows only to the separator 22 to be narrowed to the vicinity of the center of the array. When the width of the separator 22 and the thickness of the layer 2 are suitably selected, the lateral current distribution of the layer 3 and hence the gain distribution can be formed in a crest shape. Thus, the lateral mode can be controlled to the basic mode to obtain a high output integrated semiconductor laser having narrow emitting beam.
