Patent JP-H0636863-A (JP)
Title: Sheath heater
Inventor: KANAZAWA SHIGETOSHI
IPC: H05B3/48
Filed: 1992-07-14
Abstract: PURPOSE:To minimize the curvature radius of bending and prevent cracking and deformation by inserting a heating wire into a metal pipe, charging an electric insulating material, and providing a linear cable in the position for conducting bending. CONSTITUTION:In the position for conducting bending of a metal pipe 1 forming a box body, a linear cable 2 is arranged instead of a conventional heating wire. Heating wires 6 arranged in an electric insulating material 5 are connected to both end parts of the metal pipe 1. As the cable 2, those having sectional areas larger than the heating wire 6 are used. Since the density in this part is equal to that of the metal pipe 1 on the outside, the bending stress added to the metal pipe 1 on the outside is minimized when the working of the same curvature radius is conducted. Thus, the cracking and deformation of the metal pipe 1 can be reduced.

Title: Diversity receiver
Inventor: FURUYA YUKITSUNA
IPC: H04B7/08
Filed: 1985-08-26
Abstract: PURPOSE:To improve the diversity effect by changing a switching threshold in accordance with the variance of a reception electric field. CONSTITUTION:A signal 101 of the antenna selected by an antenna switching circuit 1 is not only inputted to a power detecting circuit 2 but also outputted to a receiving part from a terminal 10. When the power of the reception signal is obtained by the power detecting circuit 2, it is compared with the switching threshold stored in a memory 5 by a comparator 3 as the first comparator, and the comparator 3 outputs a switching signal 103 to the antenna switching circuit 1 if the reception signal power is smaller than the switching threshold. Simultaneously, a power detection circuit output 102 is written in the memory 5 as the switching threshold. If the reception signal power is reduced gradually by this operation, the switching threshold is made smaller gradually. If the reception signal power is increased contrarily, the switching signal 103 is not generated because the output 102 of the power detecting circuit 2 is always larger than the switching threshold in the memory 5. A comparator 4 as the second comparator outputs a memory update signal 104 when the difference between the reception signal level and the switching threshold exceeds a certain value.

IPC: G02B6/12
Filed: 1988-07-27
Abstract: PURPOSE:To obtain the light guide in which light can be effectively confined by laminating a clad layer consisting of a group II-VI compd. semiconductor on a substrate and a waveguide layer consisting of a group II-VI compd. semiconductor having the refractive index larger than the refractive index of the clad layer to a part on this clad layer. CONSTITUTION:This light guide has the structure composed of the GaAs substrate 1, the clad layer 2 consisting of ZnS and the waveguide 3 consisting of ZnSe. While the refractive index of the ZnSe of the waveguide 3 is 2.34, the refractive index of the ZnS of the clad layer 2 in the lower part is 2.31 and the refractive index of the upper part is 1.0, the difference in the refractive index is sufficiently large in the direction perpendicular to the boundary. The difference in the refractive index is sufficiently large in the direction parallel with the boundary as well because of the structure in which the waveguide layer 3 having 2.34 refractive index is sandwiched by the atm. of 1.0 refractive index. Since the difference in the refractive index between the waveguide layer 3 and the circumference thereof is large, the confinement of the light in the waveguide layer 3 is effectively executed.

Filed: 1987-07-29
Abstract: PURPOSE: To efficiently cool dough materials without blowing up a part of the dough materials by providing a control means for reversing the rotation of a fan device a predetermined time after the start of kneading. CONSTITUTION: A sirocco fan 12 feeding air into a container 18 is driven, and a control means 23 for driving a motor 3 for kneading dough materials is provided in the container 18. Since the rotation of the sirocco fan 12 is reversed by the control means 23 to the normal rotation a predetermined time after the start of kneading, no air is fed into the container 18 immediately after kneading has been started. Therefore, the dough materials in the container 18 are not blown up, and since the air is fed after the dough materials have been kneaded together, the dough materials can be cooled efficiently without being blown up. Even if the rotation of the sirocco fan 12 is reversed by the normal and reverse rotation of the motor 3, kneading can always be performed.

Abstract: PURPOSE:To improve the precision of recognition by extracting and cnverting the features of a character into a binary signal, reading and converting a dictionary, arrayed by the features, and a handwritten character into binary signals, and providing a weighting mask to a similar character part while comparing other parts with said dictionary. CONSTITUTION:An image of a handwritten character 3 is picked up by a vidicon 5, whose output is converted photoelectrically; and a segmenting circuit 6 segments the character, and a feature extracting circuit 8 extracts and classifies its features through a normalizing circuit 7. Consequently, sequential matching 9 with binary-coded characters stored in a dictionary 10 previously is performed, and thus recognition 11 is performed by using the dictionary 10. Prospective characters selected in the dictionary 10 are masked by a mask processing circuit 12 and the 2nd recognition 13 is performed. For example, three sets of (AB), (AC) and (AD) having a left hand radical (A) have right-hand radicals (B), (C) and (D) which are obviously different while having less difference in left- hand radical (A). Those left-hand radical parts are mesked and only the right- hand radicals are matched. Thus, the precision of recognition is improved while a recognition rate is increased.
