Abstract: PURPOSE:To reduce the burden of an inspector and to inspect the mirror of a plate-like plate material by forming a light source to a linear shape, and providing a photodetecting member having two pieces of linear photodetecting parts by placing an incident position of a reflected light between. CONSTITUTION:As for a light source 2, a white fluorescent lamp of 20W, etc., are used, and its length is selected suitably by a relation of width of an object 1 to be inspected and length of a photodetecting member 3. Also, in the member 3, photodetecting parts 3a, 3b are installed so as to be opposed by placing an incident position of a reflected light between, when the surface of the object 1 is completely specular. Light beams from both ends 2a, 2b of the light source 2 are reflected by two points 1ae, 1be on the object 1, and made incident on an arbitrary point 3e, therefore, data related to a state of a line between the point 1ae - the point 1be is overlapped and obtained. In the same way, a light beam from each point of the light source 2 is reflected by each point on the object 1 and made incident on each point of the member 3. If there is a defect on the surface, a halo which expands in the incident surface direction is made incident on both the photodetecting parts 3a, 3b, and made incident on plural areas of a silicon photodiode placed linearly in the direction vertical to the incident surface, therefore, a detection of a defect is executed.

Title: Preparation of decorative stainless steel
Inventor: NAKAMURA YUUZOU
IPC: C23F1/00
Filed: 1980-08-21
Abstract: PURPOSE: To form a decorative pattern having various glosses by a method wherein a pattern is printed on the surface of stainless steel with frits having different characteristics and, after baking, etching or polishing treatment is carried out to remove a part of the frit coating thickness.  
     CONSTITUTION: A surface of stainless steel is subjected to buff polishing and, by using a frit with high acid resistance and a frit with low acid resistance, a pattern with an appropriate picture pattern is printed. In this case, a coloring agent may be added to the frit with high acid resistance. The resultant printed stainless steel is baked to form a coating layer and, thereafter, a part free from the coating layer is etched by a FeCl 3  solution or polished by buff polishing or the like. Next, the treated stainless steel is immersed in a 10% HCl solution to remove only the frit with low acid resistance. The resultant part is made transparent and a metal gloss of the stainless steel is remained and a part of the frit with high acid resistance forms a opaque colored picture pattern part and a part completely free from the coating becomes a satin finished surface corroded by FeCl 3  and, thereby, a beautiful picture pattern is formed.

Title: External part for watch
Inventor: MORITA YOSHIO
IPC: C23C28/02
Filed: 1981-07-23
Abstract: PURPOSE:To decrease thickness of plated layer of precious metal and reduce cost in manufacturing plated articles of precious metal as decorative external parts by forming a foundation plated layer of Cr and then plating precious metal after activation. CONSTITUTION:In plating precious metal such as Au, Pd, Rh etc. on the surface of a decorative external part made of brass etc., Cr plating of 0.1-1mu thick is made beforehand as foundation plating, and the surface is activated by immersing in hydrochloric acid or electrolysing in hydrochloric acid. Then, it is plated with a thin layer of precious metal such as Au, Pd, Rh etc. 1-2mu in thickness. Since the foundation layer is Cr plated, corrosion resistance and decorative value are not lowered even if the thickness of precious metal plated layer is a half of conventional thickness and thus cost down can be achieved.

Filed: 1989-05-10
Abstract: PURPOSE:To enhance the processing efficiency of a device by changing a superordinate address of address sent out to plural registers for a superordinate address sent out by a latching means, coupling it with a subordinate address of addresses sent out by a processor and sending it out to plural registers. CONSTITUTION:A switching means 13 changes a superordinate address of addresses sent out to plural registers 3 - 5 by a processor 1 for a superordinate address sent out by a latching means 11, couples it with a subordinate address of addresses sent out by the processor 1 and sends it out to plural registers 3 - 5. Therefore, even if the superordinate address for discriminating the registers 3 - 5, respectively is fixed and sent out by the processor 1, the switching means 13 changes this fixed superordinate address for a superordinate address sent out by an address sending-out means 10. Accordingly, when in accordance with the address sent out by the processor 1 in order to bring a memory 2 to access, the superordinate address for discriminating the registers 3 - 5, respectively is set in advance to the address sending-out means 10, the processor 1 can select a desired register. In such a way, the processing efficiency of the device can be enhanced.

Filed: 1998-04-27
Abstract: PROBLEM TO BE SOLVED: To enhance the position detecting capability of a position detecting mechanism which uses a reflection sensor. SOLUTION: A position detection control part 50 feeds a control signal S51 to drive the light emitting diode 11 of a reflection sensor 10 for a certain period at intervals of predetermined periods to perform pulse drive. The pulse drive can increase a current flowing in the light emitting diode 11, resulting in increase in amount of light radiated.

Title: Device and system for reading coordinate
Inventor: MORITA YOSHIYUKI
IPC: G06F3/046
Filed: 1996-05-10
Abstract: PROBLEM TO BE SOLVED: To reduce the power consumption of the coordinate reader or coordinate read system. SOLUTION: A detection line 13 is laid at a sensor line part of a tablet 1. When a coordinate indicator 2 which produces a magnetic field is put close to the tablet 1, an induced signal is generated on the detection line 13. A coordinate indicator detecting circuit 15 detects the approach of the coordinate indicator with the induced signal and outputs its detection signal s3 to a tablet control circuit 16. Consequently, the tablet control circuit 16 places a coordinate calculating circuit 14 in operation mode, so a coordinate value is detected thereafter when the coordinate indicator 2 is on the tablet 1. When the coordinate indicator 2 is put away from the tablet 1, the coordinate calculating circuit 14 enters low-power-consumption mode under the control of the tablet control circuit 16.
