Abstract: PURPOSE:To improve reproducibility of an epitaxial growth layer at the III-V group semiconductor growth device according to the open tube diffusion technique by a method wherein a source boat divided into plural small cells is used, and small holes are provided at the lower parts of dashboards of the boat. CONSTITUTION:The III group elemtnts 24-27 of Ga, etc., for example, are filled up in the quartz boat 22 divided into the small cells with the dashboards 23 adding the prescribed quantity of impurity as occasion demands, and the boat is accomodated in a reaction chamber and is made to react with the V group gas material of AsCl3, etc., for example, to make it to grow epitaxially. The small holes 28 are provided at the lower parts of the dashboards 23 of the boat 22, and the source elements 24-27 in the fused condition are made as possible to transfer between the respective small spaces when reaction is to be performed. Accordingly even when growth is performed repeatedly after the source materials are filled up, because the surface area of the source and concentration of impurity in each small cell can be held at a constant, reproducibility of the growth speed and concentration of impurity of the growth layer can be improved.

Abstract: The apparatus for use in endoscopy and laparoscopy has a hand grip (1), and a shaft (2) enclosed by a movable tube (3). At the end of the shaft is a locking mechanism to fix a holder for the wound healing, or wound sealing material, for a surgical instrument. The locking mechanism consists of two arms (6), of different lengths, joined to form a 'U' shape. On the longer arm, of the locking mechanism, is an indentation (7) into which a round piece, on the holder, fits exactly. The shaft has a kink in it which produces an offset position for the manipulation area, compared to the operating area.

Abstract: PROBLEM TO BE SOLVED: To efficiently store the appearing frequency of a symbol string necessary for calculating composite probability. SOLUTION: Nodes 100 to 106 of a tree structure are provided with memories 120 to 126 for storing the appearing frequency of symbols necessary for calculating composite probability. Then, the numerator of probability is stored in the memory of a node and the denominator of probability is stored in the high-order memory of a node. At the time of calculating the composite probability that a following symbol B appears continually after a preceding symbol A, the nodes 101 and 104 are tracked from a route 100 to obtain the value of the numerator c (A, B) of probability from the memory 121 and the value of the denominator c (A) from the memory 124. With respect to the following symbol B, the node 102 is tracked from the route 100 to obtain the value of the numerator c (B) of probability from the memory 125 and the value of the denominator N from the memory 126.  N is the total number of the symbols.

Abstract: The input signal of one of the plural channels is converted by a converting circuit into frequency components which are separated into tonal components and noise components in a signal comment separating circuit. The tonal components and the signal components are encoded by a tonal component encoding circuit and a noise component encoding circuit, respectively. The amount of bytes allocated to the noise components in the respective channels is determined by a byte allocation circuit based upon time changes of the sum of the scale factors of the respective channels.

Abstract: In order to reduce the information contents of a sound signal, for example a speech signal, the sound signal is divided into adjacent frequency ranges and the signals then obtained are consecutively integrated over short time intervals to short-time-spectrum signals. Subsequently, a histogram of the short-time-spectrum signals is formed for each frequency range and said histograms are divided into a given number of equal-area portions. The boundaries of said portions, which are referred to as quantiles, represent the characteristic values. The amplifier noise or the noise of the complete recording arrangement as well as a difference in sound energy level during when different sound signals are processed can then be eliminated at least in respect of their effect.

IPC: E03C1/304

Abstract: The improved pipe flushing device comprises an elongated, elastomeric, hollow tubular member having a middle portion free to expand radially under water pressure. The rear Inlet end of the tubular member is fitted with a hose connector, while the narrow front outlet end of the tubular member contains a valve which opens upon expansion of the middle portion. The valve has a cage bearing a rear plate closure, and open sides and front. The rear plate is received in a transverse groove in the outlet, which groove is of a greater length than the thickness of the plate. The cage is gripped and held in a fixed position while the tubular member is in the relaxed unexpanded state. However, when the device is inflated by water pressure from a water hose connected to the inlet connector while in a water pipe, the middle portion thereof expands to meet the wall of the pipe. When the expansion is complete, the cage moves back in the outlet, the plate moving resrwardly in the groove to cause a mechanical vibration in the tubular member and water pipe. Waterthen by-passes the plate and passes through and out of the cage as a jet to break up a sewage clog. Upon expulsion of the jet, the middle portion contracts and the valve moves forward and closes, again causing sonic vibrations in the tubular member and water pipe. The expansion and contraction of the tubular member rapidly alternate to rapidly pulse water jets and vib ate the pipe to unclog the pipe.
