Patent JP-S58153510-A (JP)
Title: Filter
Inventor: IWAI TADASHI
IPC: B01D29/62
Filed: 1982-03-09
Abstract: PURPOSE:To reduce the quantity of turbid matters remaining in a supporting layer, and to operate a filter stably over a long perid of time, by arranging a lower filtering layer and an upper filtering layer consisting of filter mediums of small fluidizing speed on the filter-medium supporting layer, and feeding the primarily filtered water in an upward flow from under the supporting layer. CONSTITUTION:Raw water is fed from a supplying pipe 16 to an upper filtering layer 34 installed in a filtering tower 28, to perform the primary filtration in a downward flow. A part of the primarily filtered water is gathered by an upper water-gathering pipe 38, and is flowed into a lower part of the tower 28 to pass through a filter- medium supporting layer 30 and a lower filtering layer 32 in an upward flow, thereby the secondary filtration is performed, and is discharged from a lower water-gathering pipe 36. On the other hand, the remaining primarily-filtered water is flowed in a downward flow and is gathered by the pipe 36. As a result, the quantity of turbid matters captured by the supporting layer 30 are extremely decreased. In a back washing stage, air and washing water are fed from supplying pipes 24 and 26 respectively to exfoliate the turbid matters by fluidzing the layers 32 and 34 and to discharge the exfoliated matters from a discharging pipe 44. The layer 30 is not fluidized because the quantity of captured turbid matters are small, but the matters are exfoliated satisfactorily.

Abstract: PURPOSE:To more rapidly and accurately specify the cause of a fault by specifying the cause of the fault by considering the occurring degree of a fault phenomenon while dealing with a fuzzy qualitative value obtained by considering a deterioration amount read out from a storage means. CONSTITUTION:Since the fuzzy qualitative value of a parameter changed according to the deterioration amount of every previously set timing of diagnosing the fault and the occurring degree of the fault phenomenon caused by the deterioration amount are stored in an object model storage part 15, the qualitative value and the occurring degree are read out in each diagnosing timing. Meanwhile, inputted condition data is made to be the fuzzy qualitative value and the presence or absence of the fault is decided according to the value. When the fault is found, as a result, it is diagnosed by setting the parameter value changed according to the deterioration amount as an initial value. Then, the cause of the fault is identified based on the result of comparison between the condition data which is made to be the fuzzy qualitative value and the diagnosed result and the calculated occurring degree of the fault phenomenon.

Title: Embroidery data processor
Inventor: TAGUCHI SHOICHI
IPC: D05B19/08
Filed: 1997-02-20
Abstract: PROBLEM TO BE SOLVED: To simplify the shape of inner embroidering data so as to enable generating embroidery data with high quality by providing the processor with a thin line tracking means for tracking the thin line of a converted thin line image and a branch erasing means for erasing a branch when the branch exists in thin line tracking. SOLUTION: A pattern original read by an image scanner is stored as binary bit map image data, thin line conversion-processed, vector conversion-processed and stored. For example, the area of a 'cat face' is provided with inner contour lines 1 and 2 and an outer contour line 3, converted into vector data by following its route and stored in a route storage area. Branching is executed after following from an upper part in the part B of the outer contour line 3. The route from an image element 1 to the image element 3 becomes a→b→c→d. Since arrows c and d are different from the ones a and b in a direction by 180 deg., the part of the arrows a-d is erased from the route storage area. Thus, embroidery data is generated from the vector data.

Title: Multi-function terminal equipment
Inventor: UCHINO MEGUMI
IPC: G06F15/00
Filed: 1988-02-18
Abstract: PURPOSE:To interrupt an on-line process job and to perform the function of a word processor, etc., by providing a local processor which carries out a communication process to a host computer and a main processor which performs other information processes. CONSTITUTION:The firmware of a local processor 81 of a circuit adaptor 8 performs a reception process when data are received from a host computer and produces an interruption signal to inform this to a main program in an on-line mode. At the same time, the firmware carries out a transmission process with reception of a transmission command. While a main processor 1 delivers a switch instruction via a keyboard for an off-line job in case a process program is switched to a non-on-line program of a word processor, etc. Thus a mode flag of a dual port RAM 85 is set in a non-on-line mode and an on-line program is interrupted. Then the non-on-line program is started.

Filed: 1978-03-31
Abstract: PURPOSE:To avoid from being hidden with surrounding noise of viewers for a slight signal, even if the sound source having wider dynamic range is reproduced, by providing the control switch intermittently interrupting the feedback path and the attenuation selector switch interlocked with it. CONSTITUTION:The control switch S5 and the attenuation selector switch 13S are provided. The characteristics when S5 is open is as shown in curve 8, in which the output signal in proportional to the signal source obtained with the reproduction head 1 is obtained. When S5 is closed, the characteristic curve 9 is obtained, and the amplification factor is suppressed to excessive input. Succeedingly, when the switch 13S is closed, as shown in the input and output characteristics 10, the output with small signal input at which no AGC is in operation can be increased. Further, by interlocking S5 and the switch 13S, at the reproduction of the sound source having wider dynamic range, only with closing S5, slight signal can be reproduced with enough level not hidden with noise, as shown in curve 10, and to excessive input, the audio volume suppressing the output can be obtained.

Filed: 1982-03-09
Abstract: PURPOSE:To facilitate operation and to reset optionally a program searching function, by allowing a single switching means to function as a mute switch during recording or as a program search reset switch during reproduction. CONSTITUTION:Recording/reproduction changeover switches SW2 and SW3 are operatively associated with each other and during recording, they are positioned as shown in a figure to input an input signal 11 to a head H after amplification 5. At this time, when a nonlock SW4 is pressed, a voltage +B is applied through contacts (d) and (b) of SW3 and SW4 to the base of a TRQ, which turns on to shoot the output of the amplifier 5, forming an unrecorded part. When the SW2 and SW3 are switched to make a connection between the contacts (b) and (d) for reproduction, the output of the head H is passed through amplifiers 2 and 3 to drive a speaker 4 and an electric power supply +B is applied to a program search mechanism 6 as well; when a reproducing button and a fast-forward (rewind) button are pressed, a program search in automatic music selection mode starts, but when the SW4 is pressed, the program search mechanism 6 is grounded through contacts (f) and (h). Consequently, the program searching function is reset at any time.
