Title: Crystallization of semiconductor thin film and manufacture of thin film semiconductor device
Inventor: HAYASHI HISAO
IPC: H01L21/20
Filed: 1999-08-06
Abstract: PROBLEM TO BE SOLVED: To unify crystallinity when crystallizing a semiconductor thin film of a large area by overlapping laser light radiation region. SOLUTION: In a shaping process, laser light 50 emitted from a source 51 of laser light is shaped into laser light 50 having a specified radiation region and a specified intensity distribution. In a reading process, the laser light 50 is repeatedly radiated on a semiconductor thin film 2 formed beforehand on a substrate 1 by scanning so that the radiation regions may be partly overlapped. By these two processes, the semiconductor thin film 2 is crystallized. At that time, the laser light 50 is so shaped that a cross-sectional intensity distribution of the laser light 50 in the direction in which the radiation region is scanned may be of a projecting shape, in which its peak is located closer to the front end than the middle part between the front end and the rear end with regard to the scanning direction.  To be more specific, the laser light 50 is so shaped that the intensity RL at the front end of the radiation region is reduced by at most 30% from the intensity PL at the peak, and the intensity TL at the rear end of the radiation region is reduced by at least 5% from the intensity PL at the peak.

Title: Information recording and reproducing device
Inventor: TOKUMARU SHUNICHI
IPC: G11B19/02
Filed: 1993-09-09
Abstract: PURPOSE:To reduce loss in recording time for dubbing by providing a speed control means by which a storing speed to a re-storing means is made variable based on the detection result of a means for detecting a storage quantity on a reproducing side and a recording side. CONSTITUTION:A storage quantity in a shock proof memory 15 on a reproducing side is detected by a controller 16. If the storage quantity in the memory 15 is less than the usual stored quantity C', an instruction is generated by a microcomputer 8 to a frequency converter circuit 9 and a reproducing speed is increased. Then, an incompressible reproducing signal stored in the memory 15 is compressed in a recording reproducing part and stored in a memory 5. Then, the storage quantity of the memory 5 is detected by a controller 4. In this instance, if the storage quantity of the memory 5 becomes larger than the usual stored quantity C, an instruction to the circuit 9 is generated by the controller 8, lowering the frequency of a servo circuit 19 to reduce the reproducing speed. After that, more than the stored quantity C' inclusive and up to the maximum stored quantity B' are stored. Then, after the stored quantity of the memory 15 becomes B', an instruction to the circuit 9 is generated by the microcomputer 8, raising the frequency of a servo circuit 12 and increasing the recording speed.

Abstract: PURPOSE:To enable leveling-off of multiple layers of a toner on a photosensitive layer into single layer by disposing successively a hopper, doctor and impressing device in the moving direction of a moving body. CONSTITUTION:Minus corona is impressed by the 1st high-voltage power source 10 to the 1st corona electrifier 9 to electrify the entire surface of ZnO 8b as a photosensitive material to minus. When a moving body 8 moves, a doctor 11 scrapes down the conductive toner 6 on the body 8 thereby leveling off the toner to 2-3 layers.

IPC: G01N31/12
Filed: 1988-09-08
Abstract: PURPOSE:To quantitatively analyze minute C and/or S contents of a metal without a dedicated baking in a shorter time required for baking. CONSTITUTION:A heating tool 1 is used where a columnar block 11 consisting of a conductive material having a high melting point like graphite is enclosed in a quartz vessel 12 and an internal space 13 is made vacuum.

Abstract: PURPOSE:To easily switch to an infrared video movie by irradiating infrared rays from an infrared ray light emitting means and photographing at a dark place and inserting an infrared ray removing means in front of an image pick-up means and photographing at a well-lit place. CONSTITUTION:When a camera mode change-over switch 5 is pushed up to the upper side and it is turned to a regular mode, an infrared ray removing filter 9 interlocks with the camera mode change-over switch 5 and is inserted between a lens 8 and a CCD image pick-up element 10. Consequently, light to enter from the lens 8 passes through the infrared ray removing filter 9, forms an image on the CCD image pick-up element 10 and at this time, an infrared ray light is not lit up. On the other hand, when photographing in an infrared movie mode at the dark place, by pushing down the camera mode change-over switch 5 to the lower side, the infrared ray light is lit up and the infrared ray removing filter 9 is removed from the front of the CCD image pick-up element 10. Thus, a distinct picture can be easily obtained at the dark place.

Abstract: PURPOSE:To make the center of gravity of a vessel body eccentric to rotate the vessel body to obtain rotary power by forming, in the vessel body, upper and lower end chambers and an intermediate chamber housing a float and raising the float by circulating water in each chamber. CONSTITUTION:After a vessel body 3 is inclined and kept through a rotary shaft 4, water W in a lower chamber 6 is pumped up through pipes 30, 31 to an upper chamber 5 by a pump 29 at first. Next, an upper valve plate 23 is opened to drop the water contained in the upper vessel 5 in to an intermediate chamber 7 to raise the float 8 by the buoyancy of the water W. Then, a lower valve plate 24 is opened to drop the water contained in the intermediate chamber 7 in to the lower chamber 6. After that, the water in the lower chamber 6 is pumped up in the upper chamber 5 again. The center of gravity of the whole vessel body 3 is thereby positioned high than the rotary shaft 4 to rotate the vessel body 3 by 180-degree in a inclining direction. As aforementioned, the vessel body 3 is intermittently rotated every 180-degree. The rotary shaft 4 is thereby rotated to drive a generator.

As a result, the transistor 214b receives the control of the current, the current is made to flow through the transistor 214b rather than through the current mirror source 212b. Then, when the current no longer changes essentially, the transistor 214b is turned 'off'.
