Abstract: PURPOSE: To separate a signal which is sensitive to a noise from environment where there are many noises by providing two earth planes which put a plane where a signal that is sensitive to a noise is sent in between and connecting the two planes around the plane to form a Faraday cage. CONSTITUTION: A printed-circuit board 10 is completely enclosed by a Faraday cage. A 1st plane 11 is mounted on the board 10 and connected to a 2nd earth plane 12 placed on the bottom of the board 10 by means of plural vias 13. The vias 13 are substantially placed around the two planes 11 and 12 in the same way. The Faraday cage consists of the two planes 11 and 12 which effectively separate a pair of signal lines 14 and 15 from the outside interference, and the connection vias 13. Dielectric materials which constitute the planes 11 and 12 and the signal lines 14 and 15 are separated by insulation planes 16 made by means of a usual technique. Thereby, a signal which is sensitive to a noise can be separated from environment where there are many noises.

Title: Facsimile signal transmission system
Inventor: OKANO MICHIAKI
IPC: H04N1/17
Filed: 1979-02-15
Abstract: PURPOSE: To secure the high-speed transmission for the facsimile signal by giving expansion to  some high frequency component in one scanning line of the facsimile signal.   
     CONSTITUTION: The minimum duration T 1  of the black or white signal plus duration T 2  of the  subsequent white or black signal are detected, and then the detection is given to the presence or  absence of integer N which can satisfy the conditions of (2N+1)T 1 ≤T 2 . And in case N exists,  duration T 1  is expanded by NT 1 , and this correction signal is transmitted in the speed of (N+1)  times as high as the speed when no N exists. In other words, the original is scaanned in the fixed  speed at scanning part 11, and this scanning output receives the binary-coded sampling with the  pulse sent from clock pulse generator 12 to be memorized in memory device 13. Device 13  performs the alternate writing and reading with every line through 1-line memories 13a and 13b.  These actions are controlled by control parts 14 and 15. On the other hand, the scanning output  is sent to signal duration detection part 16 to detect the scanning width and then to decision part  17 to give decision to the presence or absence of positive integer N. After this, the scanning output is sent to control part 15 and then to signal expansion part 19 through OR circuit 18 for expansion. At the same time, the velocity control is given to part 11 in correspondence to the expansion, thus realizing the high-speed transmission of the facsimile signal.

Title: Processing liquid supply unit
Inventor: OTANI MASAMI
IPC: G03F7/16
Filed: 1994-01-13
Abstract: PURPOSE:To deliver stagnant bubbles along with a processing liquid while reducing the pressure drop. CONSTITUTION:A flow accelerating member 100, comprising a fluororesin rod, is inserted into the pipe part (vertical pipe part) of a processing liquid supply tube 2 extending substantially vertically to a substrate W and the vertical pipe part of a horizontal pipe part communicating therewith substantially horizontally. The flow accelerating member 100 is caulked flatly at the forward end part thereof so that it is not discharged downward, along with the processing liquid, through a nozzle 1. The flow accelerating member 100 reduces the cross-sectional area of channel at the vertical pipe part of the processing liquid supply tube 2 as compared with other parts thus increasing the flow rate thereat. Consequently, bubbles stagnant in the processing liquid are delivered along with the processing liquid through the nozzle 1.

Title: Semiconductor device
Inventor: AKIYAMA TAKESHI
IPC: H01L23/36
Filed: 1996-01-31
Abstract: PROBLEM TO BE SOLVED: To obtain sure electric contact between a plate and a radiating plate and at the same time to prevent a radiating property from being deteriorated without receiving the influence of a flash and a burr by providing a very fine protruding part for carrying a current in the vicinity of the mounting part of the plate on a radiating plate. SOLUTION: A semiconductor package 10 ensures a sufficient radiating property and is grounded through a plate 2 by bringing the surface of the plate 2 made of metal exposed on the other side into surface contact with a radiating plate 3 and at the same time mounting it to the radiating plate 3 by a screw 6. A very fine protruding part 12 for carrying a current is specially provided in the vicinity of the mounting part 4 of the plate 2 on the radiating plate 3. Therefore, even when a flash and a burr are generated in the surface of the plate 2 at the time of sealing with a resin, point contact can be surely achieved by the protruding part 12 for carrying a current. Moreover, it is prevented that the plate 2 is too much separated from the radiating plate 3 and a radiating property is lowered by the very fine protruding part 12.

Title: Brake force control device for automobile
Inventor: YOSHII HIROSHI
IPC: B60G17/027
Filed: 1986-01-27
Abstract: PURPOSE:To obtain a proper braking force corresponding to the weight of a load by raising a push up member as a wheel shaft rises relative to a body frame under the heavy load, and activating a control valve by means of a rod spring. CONSTITUTION:In no load operation, a wheel shaft 4 is moved downwards to a great extent away from a body frame 1 by the resilience of a leaf spring 2 so that a rod spring 1 restrains the control force on a rear wheel 3 without pushing the piston 12 of a control valve 10. In light load operation, the rise of the wheel shaft 4 relative to the body frame 1 is greater due purely to the sag of main spring 7, and thus the pressing force of the bar spring 16 on the piston rapidly increases so as to provide controlling force on the rear wheel 3. On further increase of load, the main spring 7 acts together with a subspring 8 which results in the lack of control force on the rear wheel 3. At that time, the rod spring 16 is pushed by means of a push member 20 so that the push force is increased. As a result, even if operated under heavy load, a proper control to the rear wheels 3 can be controlled properly.
