Title: Method for attaching internal diaphragm into steel tube
Inventor: NAKAJIMA HIROSHI
IPC: B23K9/235
Filed: 1996-02-21
Abstract: PROBLEM TO BE SOLVED: To provide such a method for attaching an internal diaphragm into a steel tube that welding is excellently performed without leaking any molten metal outside by obtaining a sufficient gap to easily and smoothly insert and automatically burying the gap, in the case of inserting the internal diaphragm into the steel tube. SOLUTION: The internal diaphragm 40 is inserted without generating catching and clogging by utilizing the gap S produced between the outer surface 42a of a backing material and the inner surface 3a of the steel tube due to the heat expansion of the steel tube 3. The gap S is automatically buried due to cooling and contracting of the steel tube 3, the inner surface 3a of the steel tube is abutted to the outer surface 42a of the backing material, and the side 40 of the internal diaphragm is combined to the steel tube 3. A welding space is formed so as to be sealed with the inner surface 3a of the steel tube, the internal diaphragm 40 and the backing material 42, whereby welding is performed without leaking any molten metal.

IPC: H01H1/66
Filed: 1997-02-03
Abstract: PROBLEM TO BE SOLVED: To prevent generation of a radiation electromagnetic wave noise by a mechanical collision between contact point metals by covering a surface of fixed contact points or a movable contact point of a high voltage relay housed in a vacuum vessel or a vessel in which inert gas is sealed, with a nonmetallic conductive layer which has high resistance and absorbs a mechanical shock.

Title: Stability control method for secondary pitch prediction filter
Inventor: TADA YASUHIKO
IPC: H03H21/00
Filed: 1986-02-17
Abstract: PURPOSE:To maintain the effect of secondary pitch prediction sufficiently and to suppress oscillations caused by a secondary pitch prediction filter by detecting the coefficient of the secondary pitch prediction and performing switching to primary pitch prediction at the time of the value of the coefficient is in an unstable area. CONSTITUTION:The output of an adder 16 is delayed by M and M+1 through a delay device 17 and supplied to the secondary prediction filter 18 in an predicting and encoding circuit at the time of the secondary pitch prediction. the transfer function P2(z) of the filter 18 is expressed by P2(z)=beta1Z<->M+beta2Z<->M<-1> after (z) conversion. In such a case, beta1 and beta2 are coefficients of pitch prediction and M is a pitch period. Then it is decided whether or not the coefficients beta1 and beta2 are in a stable area, i.e. whether or not ¦beta1¦+¦beta2¦<1 and when it is decided that a coefficient deviates from the stable area, a value calculated from an autocorrelation function f(M) = is used as the coefficient to obtain the function of the primary pitch prediction filter. Consequently, the filter is made to function as the primary pitch prediction filter occasionally, the filter operates stable on the whole without losing the features of the secondary pitch prediction filter.

Abstract: PURPOSE:To make it possible to simultaneously record the same line to the same positions of the front and back surfaces of recording paper, by making it possible to move one set of thermal heads in synchronous relation to each other so as to held recording paper between both heads. CONSTITUTION:Recording paper 12 is set between front and back side thermal heads 6, 10 by utilizing a paper presser 13 and, succeedingly, a page feed counter is reset and recording or control data is subsequently received in a predetermined data form from the interior. It is judged whether the page feed counter is zero, that is, the surface data of the recording paper 12 is being received. If said data is during reception, it is judged whether the received data is a page feed control code and, when said data is the page feed control code, the value of a page feed counter is set to +1. When said data is not the page feed control code, data to be recorded on the surface side of the recording paper is registered in a surface page buffer memory. By this method, two thermal heads are moved along the front and back surfaces of the recording paper in synchronous relation to each other and the recording data present in the buffer memory can be recorded and, therefore, recording can be performed to the same positions of front and back surfaces without shift.

Title: Sheet paper separating and conveying device
Inventor: ORIGASA FUMIHIKO
IPC: G06K13/067
Filed: 1985-02-22
Abstract: PURPOSE:To prevent duplication feed of sheet paper by providing control means to alter rotating force of the return roller. CONSTITUTION:When 2 sheets of paper 2a, 2b are picked up and duplication feed of the tissue occurs, the thickness of the paper 2a, 2b are detected by the detector 39, and the detected value is sent to the rotation force control circuit of the return roller 22. When a duplicate feed detection signal is sent to the control circuit, the controller increases the rotating force of the roller 22 to a value proximate to the friction between the pick roller 20 and the paper sheet 2 and the separation force of the sheet paper 2 is increased. In this way the overlapped-sheet 2b is pushed back to the hopper side by the roller 22 and duplicate feed is cancelled. Normally, even in case of duplicated feed of tissue where perforations catch or is wet, etc. increasing the surface friction coeff., with only a slight separation the friction between sheet of paper is drastically lowered and ensuing large separation force is not required.
