Title: Assembling and housing device for pile driver
Inventor: HATSUTORI KATSURA
IPC: E02D7/16
Filed: 1980-12-16
Abstract: PURPOSE: To stabilize a pile driver even during both pile-driving period and transporting period by automatically balancing the pile driver by a method in which the support arm of a back stay is used as a counter weight and the arm is turned in the horizontal direction.  
     CONSTITUTION: An auxiliary cylinder 5 is connected with a pin hole 6, a lower leader 1b is fixed, and a bolt is removed. Then, a back stay 14 is shrunk, an upper leader 1a is inclined backwards, a guide material 1c is contacted with the roller 20 of an auxliliary device for rising or falling the leader, a link bar 19 is inclined forwards, and the upper leader 1a is further brought down backwards. Since the lower end of the back stay 14 is coupled with the tip of the arm 8 by an universal coupler 15, the arm 8 is then closed toward the center of wheel (within transport limited width) while turning automatically in the horizontal direction at the frontal side of the wheel. Within the arm 8 serving as a counter weight, its center of gravity moves backwards during the pile driving period and also moves forwards during the transporting period.

Filed: 1994-07-07
Abstract: PURPOSE:To enhance quality and mass production capacity by applying an active energy ray through a minute hole to a resin layer underneath, dissolving a part of the resin layer irradiated with the active energy ray, forming a blind by a hole, and exposing part of a conductor pattern of a panel for an internal layer. CONSTITUTION:After a board is rinsed with water and an aqueous solution of 2% sulfuric acid and dried, an ultraviolet ray is applied to a desired second pattern part on the surface of an outer layer and a minute hole part, and exposure and development is performed. At this time, an unnecessary part of a positive type etching resist is dissolved and a second pattern is formed, and the resin layer under the minute hole is dissolved. As a result, only the resin subjected to the ultraviolet ray dissolves and a blind by a hole 9 generating no undercut can be formed. Next, the exposed part of a surface copper foil is eliminated by etching and the resist is removed. In this case, the copper foil of the panel for the inner layer is 35mum thick and the copper foil of an insulating sheet is 18mum thick. The blind by a hole 9 is of a small diameter to make it difficult for the etchant to enter.

Title: Field effect transistor and manufacture thereof
Inventor: TAKEDAI SEIICHI
IPC: H01L21/336
Filed: 1990-07-09
Abstract: PURPOSE:To restrain an electrical field from concentrating between a source and a drain without enhancing a short channel effect by a method wherein a pair of first conductive layers opposite to a semiconductor substrate in conductivity type is formed to cover a control electrode. CONSTITUTION:LDD N<-> layers 2a and 2b are formed on both faces of the side walls of a protrusion 1a. Furthermore, a source diffusion layer 3a and a drain diffusion layer 3b both of N-type higher than the LDD N<-> layers 2a and 2b in conductivity are formed on the surface of a semiconductor substrate 1 on the sides of the protrusion 1a and connected to the LDD N<-> layers 2a and 2b respectively. On the other hand, an insulating film 4 is formed on the surface of the protrusion 1a and the semiconductor substrate 1, and a gate electrode 5 is formed covering the protrusion 1a. As the gate electrode 4 widely covers the LDD N<-> layers 2a and 2b, an electrical field is restrained from concentrating locally between a source and a drain, so that hot carriers are prevented from occurring. Moreover, a short channel effect can be held down without shortening a channel section 1b in length.

Title: Vortex type shock absorber
Inventor: FUKUSHIMA NAOTO
IPC: F16F9/34
Filed: 1980-12-18
Abstract: PURPOSE:To prevent a surplus force of attenuation from generating, and to obtain desired characteristics of force of attenuation, by permitting the upper wall of a vortex chamber in a vortex type shock absorber to be disengaged from the circumferential wall of the vortex chamber so that said upper wall acts as a check valve. CONSTITUTION:When a piston 4 together with a piston rod 3 is moved down, a quantity of a working fluid in a cylider corresponding to the intruded volume of the piston rod 3 flows through nozzle holes 19 in a bottom valve 15 into the vortex 6 where a vortex results in. As a result, a force of attenuation corresponding to the working rate of the piston rod 3 results in, and the working fluid flows from a central hole 17 into a reserver chamber (not shown). On the other hand, a working fluid in a fluid chamber 11 flows through the central hole 17 of a piston valve 14 into the vortex chamber 6, and pushes up the upper wall 21 against a spring 25 to flow into a fluid chamber 10. Thus, as the upper wall 21 acts as a check valve, and the working fluid readily flows into the fluid chamber 10, desired characteristics of attenuation can be obtained.

Also, whether the continuation time when both the signals are detected is the time determined in advance by the counter 21 or not is checked, and when the former has exceeded the latter, it is decided that the training signal is detected. In such a way, a MODEM training signal can be detected exactly.
