Title: Matrix optical waveguide switch
Inventor: TAMARU NAOYUKI
IPC: G02B6/12
Filed: 1992-06-24
Abstract: PURPOSE:To improve the surface accuracy of the inside surfaces of grooves generated at the time of working the grooves by coating the inside surfaces of the grooves with a resin having the same refractive index as the refractive index of the cores of waveguides. CONSTITUTION:This optical waveguide switch has the plural optical waveguides for input light signals intersecting with each other and the discrete grooves 1 for cutting the waveguide cores in the respective intersected parts of the optical waveguides for output light signals perpendicularly to the optical waveguide forming surface. The inside surfaces of the grooves 1 are coated with the UV curing resin having the refractive index as the refractive index of the cores of the waveguides to form fresh side wall surfaces 21. The coating of the side wall surfaces with the UV curing resin is executed by a method of, for example, filling the UV curing resin into the grooves 1 and a liquid pool 2 and sucking out the UV curing resin by a nozzle connected to a vacuum pump. The amt. of the UV curing resin remaining on the side wall surfaces within the grooves is controlled by adjusting the viscosity of the UV curing resin and the position of the nozzle at this time. Since the side wall surfaces of the grooves are coated with the UV curing resin in such a manner, the fine ruggedness is masked and the irregular reflection on the surfaces is prevented. The low-loss matrix optical waveguide switch is thus obtd.

Title: Memory error detecting and correcting circuit
Inventor: KATAGIRI HIDEKI
IPC: G06F12/16
Filed: 1986-07-14
Abstract: PURPOSE:To improve error detecting capacity by providing an error detecting and correcting circuit for reading out a data of a long read-out period in order to detect and correct an error, correcting the error at the time of detecting a bit error of a memory, and rewriting the data by putting an error detected and corrected code thereto. CONSTITUTION:In an error detecting and correcting circuit 12, when a memory data input/output bus 5 is opened, a data of a long read-out period T2 is read out by a shorter period T3 (T1<T3<T2) than said period T2, an error is detected and corrected, and said data is rewritten in a memory circuit 7 as a data with an error detected and corrected code. Accordingly, by such an error detecting an correcting circuit 12, even if an error is generated in the data of the long read-out period T2, it is not left unattended during a long period T2, therefore, the probability by which a bit error is further generated in the same word becomes extremely low, and its error detecting and correcting capacity is roughly equalized to a data of other short read-out period T1. In such a way, the reliability of the data becomes high.

Title: Production indicator
Inventor: NAKAMURA YASUHIDE
IPC: G05B19/418
Filed: 1990-06-27
Abstract: PURPOSE:To enable a production indicator to be diverted to other vehicle types and productive information to be read without stopping the production indicator by disposing a means for reading memory information in the non-contact manner at the proximity of a guide chute for guiding the production indicator having a memory means received in a circular case. CONSTITUTION:A production indicating board 41 is composed of a circular case 42, a remote ID 43 as memory means and resin 44. The remote ID 43 has a function capable of reading and writing production indicating information from the outside in the non-contact manner. A memory information reading means 61 is disposed near a guide chute 31 of a production indicator 21. When the production indicating board 41 rolls on the guide chute 31 to enter a medium wave band, the medium wave W2 is sent from the remote ID43 to an antenna unit 62 by the inductive coupling of the medium wave W1, and the received productive information is transferred to a control section 64 through an interface 63. Thus, since the mechanical location of the production indicating board is dispensed with, Defective reading due to positional deflection can be prevented, and further a reading time can be shortened.

Abstract: PURPOSE:To save the consumption of silver solder in an economical way, by using silver solder wire and a flange with multiple convexes formed on it when sealing and joining the edge of an insulator container to a metal flange with silver solder in a vacuum. CONSTITUTION:When the edge of a container 1 made of an insulator, such as ceramic, is to be sealed and joined to a metal flange 4a with silver solder 9 in a vacuum chamber, multiple convexes are formed at a proper space on the outer fringe of the flange 4a so as to provide gaps between the flange 4a and the silver solder 9. The silver solder wire 9 and the flange 4a are put on a metalized layer 7 of a container 1, and the silver solder 9 is heated above its melting point to seal the container 1 which is being exhausted through the gaps between the convexes 10 and the silver solder 9. According to this constitution, the silver solder 9 is prevented from flowing out and its consumption is much saved by use of the silver solder 9 of a simple form.

Title: Pressure control valve
Inventor: MURATA HIROSHI
IPC: F16K17/10
Filed: 1982-09-24
Abstract: PURPOSE:To prevent reduction of performance due to power loss during low pressure control by installing a sealing member in the sliding part between the inner hole of a main valve and the small diameter part of a valve piece and allowing both the main valve and the valve piece to move in an integrated form. CONSTITUTION:A sealing member 9 is installed onto the small diameter part 11b of a valve piece 11 which is slidably inserted into the inner hole 4C of a main valve 4. During low pressure control, the pressure in a discharge circuit 2 which corresponds to the difference between each pressure receiving area of a valve seat 3 and a valve seat 14 is applied onto the valve piece 11 and the main valve 4. When said pressing pressure exceeds the pressing pressure of a spring 17, the valve piece 11 and the main valve 4 are shifted leftward by the resistance of the sealing member 9, and further the valve piece 11 is shifted together with the main valve 4 by the differential pressure generated before and behind the throttle 16 of the discharge circuit 2, and thus reduction of performance due to pressure loss during low pressure control can be prevented.

Title: Air-fuel ratio learning control method for internal-combustion engine
Inventor: ABE SHINICHI
IPC: F02D41/00
Filed: 1983-09-12
Abstract: PURPOSE:To prevent degradation of the driving performance and the specific fuel consumption of an engine, by executing learning control when an intake throttle valve and the engine load are feedback controlled under specific conditions and the atmospheric pressure is higher than a predetermined value. CONSTITUTION:A control circuit 61 executes learning of values to be learnt when an intake throttle valve and the engine load are feedback-controlled under specific conditions and the atmospheric pressure is higher than a predetermined value. For this purpose, judgement is made at first that the throttle valve is not in its idling position, and then judgement is made whether the pressure PM in an intake pipe has entered into learning region or not. In case that the judgement is YES, learning of values to be learnt is executed when the air-fuel ratio is under feedback control, the temperature THW of engine cooling water becomes higher than a prescribed value, the atmospheric pressure PMA becomes higher than a prescribed value and an air-fuel ratio feedback correction factor FAF is skipped. By employing such a method, it is enabled to reduce the number of bits of memory and the number of words of a program and to prevent degradation of the driving performance and the specific fuel consumption of an engine due to errors of learnt values.
