Title: Manufacture of semiconductor element
Inventor: KUNIO TAKEMITSU
IPC: H01L27/00
Filed: 1984-12-26
Abstract: PURPOSE:To enable the manufacture of the semiconductor element of a substrate for SOI with a photoresist process omitted by making only the par, which is to be a semiconductor element region of a polysilicon film, single crystal by beam annealing and fabricating a semiconductor on the remaining single crystal silicon after removing the polysilicon film which has not been made single crystal by etching. CONSTITUTION:Only the element region 6 on an SOI substrate (Si substrate 1) is heated by laser beams 5 by using a laser annealing device so as to fuse a polysilicon film 3 of the element region 6 and make it single crystal. After removing a reflection preventing film 4 by etching, the SOI substrate subjected to laser annealing is immersed in the mixed etching solution and is etched till the polysilicon film 3 id removed. Thus only the element region 7 which has been made single crystal can be left o an SiO2 film 2 on an Si substrate 1. Then a semiconductor element is fabricated on the remaining single crystal silicon.

Title: Frame synchronization system
Inventor: MINATO DAISAKU
IPC: H04J3/06
Filed: 1984-12-27
Abstract: PURPOSE:To economize the titled system by aligning framehead signals by the frame aligning part at the end of the transmission line, then removing the synchronizing circuit for each state frame from the transmit interface part furnished in the transmittal connecting line in the exchange station. CONSTITUTION:A read counter 44 causes a frame aligning circuit 33, by the time signal CLK in the exchange, to synchronize the outputs of the frame, and directs an MF synchronizing circuit 46 to take in the status signal (ST-) of each frame. The MF synchronizing circuit 46 synchronizes multiframes (MF) under the informing by the read counter 44, and likewise takes in the state signal (ST-) of each frame that is ordered in the prescribed position from the transmit signal on a link 15, as well as temporarily stores the signal in a buffer memory circuit 48, then transmits to the controlling part via a signal line ST. Therefore, the circuitry conventionally provided to take out each signal in the state frame in matching with the order of the controlling actions of the exchanger and output to the buffer memory circuit, is made unnecessary. In such a way, the state signal is taken out only by synchronizing the multiframes. As a result, the transmit interface part of the exchanger is economized.

Title: Pipe joint
Inventor: SHIMADA HARUMI
IPC: F16L33/22
Filed: 1989-10-25
Abstract: PURPOSE:To reduce a quantity of working by installing a nipple with both large and small diametral hole parts, a socket free of detachment with this nipple and decreasing its inside diameter toward the side of an opening, a sleeve slidable on the outer circumference of the small diametral hole part of the nipple, and a collet capable of contracting its diameter when it slides in the axial direction inside the socket, respectively. CONSTITUTION:When a hose is connected to a pipe joint, an edge of the hose H is inserted into space between an outer circumferential surface of a sleeve 3 and an inner circumferential surface of a collet 4 till it comes into contact with a step part of a nipple 1. When internal pressure is added to the hose H, the sleeve 3 is moved to the side of the opening 20 with the hose H and the collet 4 together. An outer circumferential surface 40 of the collet 4 contacts with a taper surface part 21, the collet contracts its diameter, and the hose H is clamped between the inner circumferential surface of the collet 4 and the outer circumferential surface of the sleeve 3. When an outer sleeve 24 is put back to the side of the socket 2 against a spring 27, the hose is thus separable. With this constitution, working of the small diametral hole part can be done by outer turning and the taper surface part by drawing of a pipe material, respectively.

Title: Piston
Inventor: SANADA AKIRA
IPC: F16J1/00
Filed: 1985-12-12
Abstract: PURPOSE:To reduce slapping noise of a piston by dividing the piston into a crown part for attaching pistion rings, and a skirt part for installing the piston, and by connecting the both parts to a connecting rod by means of a piston pin. CONSTITUTION:With a crown part 1a connected via a piston pin 3a movably to a skirt part 1b, compressive forces of air are received with the crown part 1a and the skirt part 1b receives only lateral pressures. Accordingly, since the lateral pressures are received with the entire side surface of the skirt part 1b and the piston slides not in a tilted condition, the sliding becomes smooth to reduce slapping noise of the piston.
