Title: Formation of mono-crystal semiconductor layer
Inventor: HOGARI YASUAKI
IPC: H01L29/78
Filed: 1978-09-27
Abstract: PURPOSE: To facilitate obtaining of mono-crystal layer by forming non-crystalline semiconductor layer on a surface of insulative layer disposed on insulative substrate or semiconductor substrate and contacting seed crystal of mono-crystal therewith and heat-processing to mono-crystallize.  
     CONSTITUTION: An insulative layer 2 resistable against high temperature of 1100°C such as SiO 2 , Al 2 O 3 , Si 3 N 4  is deposited on a Si substrate 1 and a multi-crystal Si layer 3 is deposited thereon in thickness of 1000W5000Å. Then, acceleration voltage for ion impacting is selected in order that 80% of thickness from the surface of the layer 3 is made non-crystalline and ions such as Ar, Ne, B and P are impacted. Then two mono-crystal Si pieces 5 are contacted with one part of the surface of the layer 3 and between them high electric current is applied in short time so as to mono-crystallize the layer 3 just under the Si pieces 5 and it is effected on whole layer 3 in short time and all layer 3 is mono-crystallized 35. Thus, formation of mono-crystal layer is simplified and defect of crystal practically becomes no harm degree.

Title: Porous liquid absorbing sheet and its manufacture
Inventor: TABUCHI KUNIHIRO
IPC: A61F13/00
Filed: 1990-05-09
Abstract: PURPOSE:To prevent the back flow of a body fluid once absorbed, prevent the shape destruction of a sheet, and provide a liquid absorbing sheet keeping the soft touch for long by adhering a rear face film to the bottom ends of the projections of a surface side film having a number of tapered projections. CONSTITUTION:A surface side film 1 has a number of tapered projections 3, and a rear face side film 2 is adhered to the bottom ends of the projections 3. The inner surface of the projection 3 forms a tapered hole 4 extending through, and the part other than the tapered holes 4 is enclosed by the films 1, 2, and forms a closed air chamber 5.

Title: Self-driving method of truck
Inventor: TATSUMI HIROSHI
IPC: G01R13/22
Filed: 1983-07-04
Abstract: PURPOSE:To set easily a driving target and to improve greatly the working efficiency by keeping the differences of angles formed by the straight lines connecting markers and left and right image sensors and center line of a truck within a set range respectively. CONSTITUTION:Markers 6 and 7 are set on a virtual driving target (lc) with a prescribed distance (y) secured between them. The images of markers 6 and 7 are projected to a pair of image sensors 4 respectively. These sensors 4 detect the right-left displacement distance to optical axes (lb) of those images. Based on the result of this detection, each camera 5 calculates successively at the angles theta1a, theta1b, theta2a and theta2b formed by markers 6 and 7 respectivly through an automatic controller. Then an automatic controller controls an automatic steering device to a driving device 1 so as to maintain relations theta1a-theta1b<=epsilon1 and theta2a-theta2b<=epsilon2 in terms of the absolute values of said angles. Thus the direction and the right-left position can be corrected for a truck body A.
