Title: Mode synchronous laser device
Inventor: TAKADA ATSUSHI
IPC: H01S3/083
Filed: 1990-02-05
Abstract: PURPOSE:To form a mode synchronous laser device for stably generating an optical pulse by disposing a period transmission type optical filter having transmission properties of a period equal to the driving frequency of optical modulating means in a light circulation passage in a laser oscillator. CONSTITUTION:In order to circulate a light between an optical amplifying medium 1, optical modulating means 2 and a period transmission type filter 6 in a ring type laser resonator, mirrors 7, 8, 9 are respectively disposed between the medium 1 and the means 2, the medium 2 and the filter 6, and the filter 6 and the medium 1, and an output pulse light is output from the mirror 7. Since the filter 6 having transmission properties and a period (f) equal to a driving frequency is inserted into the resonator, only a group of phase- synchronized vertical mode is output without loss of the filter 6, the other two groups are subjected to strong loss, and not almost output. Accordingly, since only the phase-synchronized mode is selectively oscillated at an interval of the period (f), a stable optical pulse can be obtained.

Title: Production of aromatic polyphosphate polymer
Inventor: KOBAYASHI ETSUROU
IPC: C08G79/02
Filed: 1979-03-05
Abstract: PURPOSE: Halogen-containing aromatic polyphosphate polymers are made to react with a compound with an active hydrogen atom to replace the chlorine with the residue of the compound, thus producing said aromatic polyphosphate polymers capable of forming self-extinguishable materials by adding to various kinds of high-molecular materials.  
     CONSTITUTION: Almost equal amounts of phosphorus oxychloride and an aromatic diol as hydroquinone, 1,1-bis(4,4'-hydroxyphenyl)cyclohexane, are made to react to form an aromatic polyphosphate of formula I (Ar is aryl; n is 2 or more integral number), which is consequently made to react with a compound bearing an active hydrogen of formula II (R is the residue except the active hydrogen), as methanol or phenol, in an organic solvent as dioxane. Then the solvent and the unreacted compound are removed by distillation to obtain the aromatic polyphosphate of formula III which is derived from the polymer of formula I by substituting the chlorine atoms with the residue of compound II.

Abstract: PURPOSE:To ensure an easy attachement and detachement of a photoreceptor to/ from the copier main body, by providing a guide mechanism to the lowr casing to give a guidance to the photoreceptor from the supporting position to the open-side end of the casing when the photoreceptor is attached and detached. CONSTITUTION:To detach the photoreceptor 4 from the support mechanism 20 that performs the maintenance and exchange, the knob 28 is held and then pulled toward the arrow mark at the front side and against the elastic force of the holder spring 31. Thus the flat part 32a of the 2nd flange 32 is detached from the end part of the photoreceptor 4 and also from the taper part 32b. In such way, the end part of the photoreceptor 4 secures a gap to the flange 32, and thus the photoreceptor 4 is supported artificially. Thus the other end part of the photoreceptor can be detached from the 1st flange 26 with some distance. As a result, the photoreceptor 4 is released from the mechanism 20 and then supported automatically at the guide mechanism 40 provided at the prescribed area, i.e., at the lowr part of the mechanism 20.

Filed: 1983-02-17
Abstract: PURPOSE:To reduce feedback capacitance between a gate and a drain by forming an insulating section shaped by partially oxidizing a gate electrode film to approximately the central section of the gate electrode film. CONSTITUTION:An N<-> layer (c) functioning as a drain is formed on an N<+> type Si substrate (a), and P type well regions (d) serving as channel regions are formed to the layer (c) and N<+> type well regions (e) functioning as source regions in the regions (d). A gate oxide film (g) is formed between the regions (d) and (d), and a gate electrode film (h) is formed on the upper surface of the film (g). In a vertical type MOSFET shaped in this manner, the area of the electrode film opposite to a drain region is reduced because an insulating section (i) is formed in a predetermined region at approximately the central section of the film (h). Accordingly, feedback capacitance between a gate and the drain is reduced, and the speed of switching can be increased.

Abstract: PURPOSE:To enable analysis of dust such as specification of a dust source by determining the components of a foreign matter through detecting a dust with specific components by the use of an excitation filter. CONSTITUTION:A white light is directly impinged from a light source 3 onto a wafer 2 by a mirror 4 and an irradiation hole 8 without passing through an excitation filter 5. In this case, when an inspection stage 9 is moved in the XY-direction, the scattered light (first reflected light) of dust stuck at a specified place on the wafer 2 is received and detected by a photoelectric converter 6. Continuously, the white light from the light source 3 is caused to go via the excitation filter 5 so that the excitation light of only a wavelength required for excitation is applied onto the wafer 2. The scattered light (second reflected light) of dust by this excitation light passes through the mirror 4 and only a fluorescent image is taken out therefrom by a cut-off filter 10. The fluorescent image is the image of only an organic dust to be received and detected by the photoelectric converter 6. The organic dust is detected by means of the white light and excitation light.
