Abstract: PURPOSE:To prevent the generation of cracks on an Si film pattern when it is recrystallized by a method wherein a thick non-single crystal Si film is left between patterns by performing a controlled etching thereon, and the remaining Si film is removed after recrystallization. CONSTITUTION:An insulating film 12 is formed on a substrate 11, and the non- single crystal Si layer having the thickness of several tens of times or thereabout of the film 12 is deposited on the film 12. Then, a resist pattern is formed on said Si layer, element forming regions 14 are formed by performing a controlled etching thereon, and a non-single crystal Si layer 13a is left between the regions 14. Subsequently, after the regions 14 are fused and recrystallized by projecting an electron beam, the layer 13a is removed. According to this method, as the layer 13a is left when the region 14 is fused, the exfoliation of the region 14 from the film 12 and the generation of cracks in the region 14 can be prevented.

Filed: 1983-08-31
Abstract: PURPOSE:To measure a film thickness in on-line by applying wavelength characteristics to obtain the film thickness of an object to be measured, whose optical constant is known and only film thickness is changed, immediately in accordance with the wavelength of extinction. CONSTITUTION:A white light which is irradiated from a light source 10 and has continuous spectral components pass a monochromatic light selecting unit 20, and only a monochromatic light having a designated wavelength is irradiated to an object S to be measured. This wavelength is selected by a wavelength selecting signal from a film thickness measuring device 30. The monochromatic light irradiated to the object S at an angle phi of incidence is reflected at the angle phi of reflection. A detector 40 detects this reflected light through an analyzer 41 and outputs a light quantity signal corresponding to the quantity of this reflected light. The film thickness measuring device 30 detects a wavelength lambda, where the quantity of light is zero, in accordance with this light quantity signal and uses this wavelength lambda to operate a formula and obtains a film thickness (d) of the object S. The variation of the extinction wavelength lambda is observed while repeating wavelength sweep to obtain the film thickness (d) continuously.

Title: Manufacture of patterned film for polyester decorative laminated board
Inventor: NIWAYAMA AKIRA
IPC: B29D7/00
Filed: 1982-09-14
Abstract: PURPOSE:To obtain the film capable of reappearing fine unevenness cheaply and excellent in properties of repeated use and frame stick by a method in which after an image has been given on one surface of the film by using contractive resin, unevenness is formed on the opposite surface of the film on account of the contraction of said resin.

Next, only the part of said film applied with resin 2 is protruded by expansion to the surface opposite the surface with the image applied, by the contraction caused to occur on account of drying and curing the resin, whereby uneven surface is formed, and thus the patterned film 3 for decorative laminated board may be produced.

Filed: 1990-06-19
Abstract: PURPOSE:To prevent a test mode from being erroneously set when a power source is turned on by connecting a power source ON reset means to an external the inverse of RAS input means and connecting the delay means of the power source ON reset means to an external the inverse of WE input means. CONSTITUTION:When the power source is turned on, a power source VCC is fluctuated from an OV level to a VCC level and while receiving this fluctuation, power source ON reset signals POR1 and POR2 are respectively fluctuated form an L level to an H level. Then, an internal the inverse of RAS signal, internal the inverse of CAS signal and the internal the inverse of WE signal are fluctuated to the H level, and reset is started. Continuously, the signal POR1 is fluctuated from the H level to the L level earlier than the POR 2, and the internal the inverse of RAS signal and the internal the inverse of CAS signal are fluctuated to the L level after completing the reset. Further, since the signal POR2 is fluctuated from the H level to the L level, the internal the inverse of WE signal is fluctuated to the L level after completing the reset. Thus, the test mode is not set when completing the reset.

Title: Spark ignition gas internal combustion engine
Inventor: MORI SHUNICHI
IPC: F02B43/00
Filed: 1991-06-06
Abstract: PURPOSE:To improve the safety to ignition of blow-by gas by blowing inactive gas into a crank case when the concentration of flammable components in the blow-by gas leaking to the crank case is an easy-to-be-ignited concentration. CONSTITUTION:Blow-by gas blowing through into a crank case 14 as an engine 11 is operated, is discharged out of the engine 11 through a blow-by gas discharge tube 32. A flammable gas concentration sensor 34 detects a concentration of flammable components in the blow-by gas flowing through the blow-by gas discharge tube 32, and outputs a detection signal to a controller 40. When it is determined based on the detection signal that the blow-by gas is within a flammable concentration range, the controller 40 controls valve opening action for an solenoid switching valve 39 to let an inactive gas cylinder 36 with the inside of the crank case 14. Inactive gas is thus sent to the crank case 14 to decrease the concentration of the flammable components in the crank case 14, thereby safety to ignition of the blow-by gas is improved.

The noise signal is full-wave-rectified, compared at a comparison circuit 10, where an output of a high or low level is obtained with a rectified voltage level. Every time a monostable mltivibrator 11 is operated, the output is inverted. This output switches a changeover switch 13. When the changeover switch 13 is opened, a reference voltage of a comparison circuit 5 depends on 4A, 4C and a light emitting diode 1A is driven so as to obtain an optical output corresponding to the reference voltage.
