Title: Optical power branching device
Inventor: ONO ATSUSHI
IPC: H04B10/29
Filed: 1990-03-08
Abstract: PURPOSE:To attain branching as required and to make the branched optical power constant and to relax the limit of a multi-stage connection number by variably controlling a control voltage to a directional coupler optical device inserted in an optical transmission line. CONSTITUTION:A directional coupler optical device 6 is inserted to an optical transmission line so that optical transmission lines 5A, 5B are connected respectively to an input terminal 61 and a 1st output terminal 63. The directional coupler optical device 6 varies a rate of output to 1st and 2nd output terminals 63, 64 in response to a control voltage given externally. Then a branch rate control circuit 7 controls the directional coupler optical device 6 at application of power so that the light from the input terminal 61 passes as it is to the 1st output terminal 63. Moreover, the branch rate control circuit 7 controls the directional coupler optical device 6 so that the power of the branched light from the 2nd output terminal 64 is a prescribed value. Then the limit of multi- stage connection is relaxed, the branched optical power is made constant and branching as required is attained.

IPC: G05B11/36
Filed: 1990-03-08
Abstract: PURPOSE:To attain the change of the set value via an on-line system by designating previously the set value to be changed in a prepared set value area and then transferring totally this set value area to the same area of a function generator. CONSTITUTION:A changing set value area 3 is prepared in a function generator 1 and an area transfer instruction 4 is carried out. Thus the set value is totally transferred to a set value area 2 of the generator 1. The instruction 4 is carried out when an execution instruction 5 is carried out with an access C given from a maintenance tool 11 and then a transfer instruction execution signal (d) is inputted to the instruction 4. Meanwhile the signal (d) is inputted to a clear instruction 6 and outputted as a transfer instruction execution clear signal (e). This signal (e) is inputted to the instruction 5. In such a constitution, the set value of the generator 1 is changed in an on-line system and furthermore the tool 11 is just required to perform an access to the instruction 4 only.

Title: Method for controlling pump for bubble bathtub
Inventor: MIWA EIJI
IPC: A47K3/00
Filed: 1994-02-28
Abstract: PURPOSE:To change the vibration of an external circulating piping to confirm a reduction in vibration level, when the takeout hole of a bathtub body is clogged and partially blocked, thereby judging a partial blocking, and perform a prescribed pump control such as pump stop. CONSTITUTION:When a pump 18 is started by the input operation of an operation switch 28, bathtub water is externally circulated, and the frequency detected by a vibration sensor 32 in an external circulating piping 14 is inputted to an amplifier circuit 38. The frequency is amplified there, and the magnitude of the frequency is compared with a set threshold P1 in a comparator 40. The number is counted by a count circuit 42 every time when the detected frequency exceeds the threshold P1. When the count number is smaller than a set first standard count number, the partial blocking of a takeout hole 12 is judged, and a prescribed control such as pump stop or reduction in pump rotation is carried out. As occasion demands, the abnormality is displayed in a display part 30.

Title: Controller for printer
Inventor: ASANO SADAJI
IPC: G06F3/12
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To obtain a controller for a printer wherein the controller for the printer connected to a printer in which printing data are controlled in a file unit, can surely identify the file. SOLUTION: When a file is forwarded to a printer so that the file is printed with a controller for printer, the file can be forwarded by annexing another file name different from a file name for the controlling for printer. The printer can have a same file name for two or more files. In such the case, the controller for printer comes to be incapable of identifying the file. Herein, the controller for printer forwards the file by a file name to which an identification character is annexed. Since an identification character which is preliminarily not used for an identification character for another file is selected as the identifying character, the file can be surely identified by using the identification character.

Abstract: PURPOSE:To branch an incident optical power to an arbitrary one optical waveguide to N output optical waveguides uniformly by forming the input of the center part of a slab optical waveguide and the core width of the output optical waveguide smaller that that of a peripheral part and that of the output optical waveguide other than that. CONSTITUTION:An input optical waveguide array is the aggregate of a large number of input optical waveguides 1, and an output optical waveguide array is the aggregate of the same number of output optical waveguides 2 as that of the input optical waveguides 1. Those input and output optical waveguides 1, 2 are constituted of rectangular optical waveguides covered with clad with different re-fractive indexes, and they are arranged at both terminals of the slab optical waveguide 3 confronting with each other. The core width of the input and output optical waveguides 1, 2 in the center part are formed smaller than that of the peripheral part, and light of unrequitrd mode easy to generate in the center part is given away to the outside the waveguide by narrowing down the core width. As a result, the incident optical power to one optical waveguide can be branched to N output optical waveguides uniformly.

Title: Signal detector

IPC: H04Q1/448
Filed: 1982-04-02
Abstract: PURPOSE:To stabilize control signal deciding operation by using the counted time of a counter for deciding a control signal. CONSTITUTION:The control signal passed through a band-pass filter 11 is compared with the reference voltage of a reference voltage source 13 and sent out as a rectangular wave signal. This rectangular wave signal is sent out to the set terminal of a flip-flop 14 and also to the reset terminal of the counter 15 to prevent the flip-flop 14 from being reset. The counter 15 starts counting for a specific time once the level at its reset terminal varies from H to L to send out an H signal to its output terminal when the level at the reset terminal does not go down to H again. Consequently, the output of the flip-flop 14 is held at H as far as the rectangular wave of the control signal is inputted within the specific time, and a counter 16 continues to count the holding time.
