Title: Resin-made optical circuit board and its manufacture, and domestic electric appliance using the same
Inventor: TAKEYA NORIAKI
IPC: G02B6/122
Filed: 1990-09-17
Abstract: PURPOSE:To obtain the inexpensive optical circuit board which has superior optical characteristics and large mechanical strength by constituting a clad part in two-layered structure of a substrate and a skin layer covering its surface. CONSTITUTION:The clad part is constituted in the two-layered structure of the substrate 1 and the skin layer 2 which covers its surface; and the substrate 1 of the clad part is formed of a material which has larger mechanical strength and higher heat resistance than the skin layer 2, which is formed of a material which has a lower refractive index than a core part 1. Consequently, only the skin layer positioned at the periphery of the core part is considered as to the low refractive index of the clad material 1 and an inexpensive material which is easily obtained in consideration of mechanical strength and heat resistance can be selected as the substrate material of the clad part 1 without considering the refractive index. Namely, the mechanical strength and heat resistance of the clad part of the optical circuit board are obtained with the substrate and the optical characteristics are realized with the skin layer; even when inexpensive fluororesin of several mum order in actual use is used for the skin layer, the price is made lower than before.

Abstract: PURPOSE:To accurately recognize the echo fault generated in a telephone exchange by providing a burst signal duration detecting means and a signal level measuring means or the like to a receiver side equipment so as to measure the receiver echo level quantatively in two-wire line. CONSTITUTION:A control section 33 of a receiver equipment detects a burst signal from an output signal of an amplifier 31, gives a level 1 as a selection control signal when the signal amplitude is a prescribed level or over to a signal selection section 32, which cuts off a signal passing during the level 1. Then a selection signal output 36 from a variable attenuator 35 and a comparison signal output 37 being a branched output of the amplifier 31 are given to a level meter 39 via a switch 38 and the attenuator 35 is adjusted so as to make the deflection of the meter 39 equal by switching the switch 38. As a result, even if the switch 38 is switched, the meter 39 shows no change in deflection, the sum of the gain of the amplifier 34 and the gain of the attenuator 35 is a relative level of echo. Thus, the echo level is measured quantatively and the echo fault is accurately recognized.

Title: Method for generating file
Inventor: SASAKI TOYONARI
IPC: G06F12/00
Filed: 1993-10-04
Abstract: PURPOSE:To discriminate the text/binary of a file without troubling a user and to avoid a fault on use by deciding the system of data to be written, writing a discriminator in a prescribed system and writing data by the decided system after the discriminator. CONSTITUTION:The first records of the respective files are the discriminators showing the system of data. In the case of a text, 'TEXT' is written, and 'BINA' in the case of a binary. In the case of the file by the text, the number of data is written by the text in a second record. Data is written in third and subsequent records. In the case of the file by the binary, an integer value showing the number of data is written into the second record and real number data are written by the binary in the third and subsequent records. Thus, the system of data subsequent to the discriminator can be judged based on the discriminator written in the prescribed system and the file can be opened by the same method.

Title: Device for preventing centrifugal ejection of grindstone and the like
Inventor: OKAMOTO MASAHIRO
IPC: B24B41/04
Filed: 1985-11-04
Abstract: PURPOSE:To aim at preventing the risk of a grindstone due to the inertia force of the grindstone upon breakage of a grindstone rotary shaft, by fastening coupling members at both ends of the grindstone rotary shaft with the use of headed bolts through the intermediary of thrust bearings, and by attaching a grindstone device to the coupling members. CONSTITUTION:A grindstone shaft 20 is rotated by a built-in motor 41. A grindstone 35 has a holding device 34 attached to a first coupling member 27, and is rotated by a shaft 20. When the rotary shaft 20 is broken, the shaft will come to an abrupt stop. The grindstone 35 is to rotate by an amount larger than that of the shaft due to its inertia force, and therefore, the mating surface of the first coupling member 27 is separated. At this time the force to rotate the grindstone is prevented from being transmitted to a headed bolt 31 due to the provision of a thrust roller bearing 33 disposed therebetween, and therefore, the bolt 31 is never twisted off. Accordingly, it is possible to prevent the grindstone 35 from being ejected while it is rotated.

Filed: 1992-09-17
Abstract: PURPOSE:To simplify the structure of a device and increase a detection range by providing a plurality of light-intercepting elements in the symmetrical position to the center line of a direction finding device so as to be inclined outwardly. CONSTITUTION:This direction finding device has a plurality of light-intercepting elements 1, 2 in the symmetrical position to its center line C. The light- intercepting elements 1, 2 respectively have a circular light-intercepting surface and at the same time are so provided as to be inclined outwardly by an angle (theta) to the line C. The direction finding device is mounted on an airframe with the line C accorded to its shaft to receive the reflected light R of laser L radiated to a target T from the ground. When the direction of the target T is displaced from the line C, for instance, the light-intercepting area of the element 2 becomes larger than that of the element 1, so that a difference in the output is produced with a difference in a quantity of light to the elements 1, 2. The outputs of the elements 1, 2 respectively are amplified by the respective amplifiers 3, 4 and then compensated for in calibration circuits 5, 6. The difference in output between the elements 1, 2 is sought in a signal processor 7, thereby making it feasible to find the direction of the target T (angle to the line C).
