IPC: G06T1/00
Filed: 1984-06-06
Abstract: PURPOSE:To obtain a specified detection accuracy regardless of variations in the quantity of light due to intense noise without cutting back the amount of information by dividing optical detection output from the surface with expected deficiency into two areas to check defects by comparison of the quantity of light therefrom. CONSTITUTION:The right side of a defect like a dent of an object 1 to be inspected is lighted slantly at such an angle as causing total reflection and an image data thereof is taken in with a TV camera for a software processing with a CPU. Right and left masks 8a and 8b are set in the image of the object 1 corresponding to the surface with an expected deficiency. The average quantity of light in a T-shaped mask 10 comprising blocks No.1, 3, 4 and 6 is calculated concerning the mask 8a having 16 blocks 9 and then, sequentially the average quantity of light is calculated up to the mask 10 covering blocks No. 10, 13, 14 and 16 to extract the maximum thereof as data A. Likewise, the average quantity of light of the mask 10 concerning the mask 8b is calculated to extract the minimum thereof as data B. The comparison of data A and B enables the identification of accepted and rejected products as a specified detection accuracy.

Title: Insertion to external auditory miatus type headphone
Inventor: KOMAKI SHIYOUJIROU
IPC: H04R17/00
Filed: 1982-07-05
Abstract: PURPOSE:To obtain good characteristics both in sound pressure and sound quality by making the diaphragm breathing spherical form. CONSTITUTION:A film diaphragm 12 is a spherical body called a breathing sphere. It changes its radius and axial length that is, expands and contracts, and emits nearly ideal spherical wave. A driving section 13 is a member to drive the diaphragm 12. A frame 14 supports directly the diaphragm 12 and driving section 13 when inserted to the ears and prevents attenuation of sound caused by direct contact of the diaphragm with external auditory miatus.

Filed: 1983-06-30
Abstract: PURPOSE:To obtain a fixing roller stable in inside condition, free from change with the passage of time, high in mass productivity and excellent in temperature distribution by making the inner surface of a fixing roller having built-in heat source of an anodized metal. CONSTITUTION:After making well-known chemical polishing process on the inner face of a fixing roller made of Al manufactured by drawing etc., the surface of Al is oxidized to make an alumite layer 1' by well-known alumite processing. A stable roller small in scattering of internal reflection factor, free from change with time can be obtained by the roller 1. The reflection factor of internal radiant heat can be controlled by changing the thickness of the layer 1'. In this case, good result can be obtained by making the thickness of the layer 1' 3-15mu. Thus, the quantity of radiant heat received by a temperature fuse 11 from a heater 5 is nearly constant. Accordingly, change of temperature of the fuse 11 is influenced by temperature of the roller 1 instead of radiant rays from the heater 5.

Abstract: PURPOSE:To make it possible to carry out a high precision position detection by installing magnetic resistance elements in motor driving devices and feeding back the positions of doors detected by the magnetic resistance elements. CONSTITUTION:A door 11 carries out changeover of an air intake port. Air taken in is heated by a heater 8, and is cooled depending on the opening degree of a door 21 to a suitable temperature by a cooler 9. Thus, the air is ventilated through respective blow-off ports by the opening or closing of doors 31, 32 and 33. Motors 1a, 2a and 3a are contained in motor driving devices 1, 2 and 3, and magnetic resistance elements 1b, 2b and 3b are provided therein. Signals of a sensor 6 and an operating switch 5 enter into a control circuit 4d, and a positional signal is emitted therefrom. The position of this signal is compared with the current position. When the former position deviates from the latter, the motor 2a is driven by a drive circuit 4a, and the door 21 is moved to a predetermined position to control the temperature of air. The positional signal knowing the current position detects a magnetic flux variation due to the rotation of the motor by the magnetic resistance element 3b, and is detected as a rotational pulse.Hence, it is possible to know the current position. With respect to the doors 11, 31, 32 and 33, similar procedures are carried out.
