Title: Modulator and demodulator for optical communication
Inventor: SHOJI IWAO
IPC: H04B10/07
Filed: 1995-10-06
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of an error during transmission by modulating each digit of a digital signal into an optical different wavelength and providing an output of mixed optical signals thereby simplifying the circuit configuration. SOLUTION: An A/D converter 11 is used to convert an analog signal AS into a digital signal DS having an optical number of digits, and the signal is outputted from a register 12 in parallel with respect to the digits D0 -D3 . Then a drive circuit 14 drives and lights up light emitting elements 13a-13d corresponding to the digits D0 -D3 outputted from the register 12. The emitted lights with wavelengths λ0 -λ3 are mixed by a dispersion prism 15 to obtain an optical output ΣD. Thus, in the case of transmission of the analog signal AS, highly accurate transmission nearly equal to that by pulse code modulation is attained and occurrence of an error during transmission is avoided without employing complicated configuration. Furthermore, a modulator 10 is realized with conventional components and circuit configuration to reduce the cost of the modulator and demodulator.

Title: Copying machine
Inventor: HONDA YOSHITAKA
IPC: G03G21/00
Filed: 1989-10-31
Abstract: PURPOSE:To eliminate wasteful operation of a driving system by displaying the switch of copying condition setting to an initial condition when a power saving mode is executed after a stand-by condition, and, on the other hand, performing the operation of the driving system, which is involved in the switch of the copying condition setting, during a period of time from the cancellation of the power saving mode to the start of the copying operation of the next cycle. CONSTITUTION:A control means 1 is composed of a CPU 7 and a magnification switching/controlling part 8. The CPU 7 operates so that the power saving mode is executed after the stand-by condition, where copying can be carried out, following a copying operation is continued for a fixed period of time, and so that when a print switch 14 on a display part 2 is turned on, the power saving mode is cancelled to resume the copying operation. During the period of time from the cancellation of the power saving mode to the start of the copying operation of the next cycle, the driving system involved in the switch of the copying condition setting is operated. Even if a main power source is shut off at the time of the execution of the power saving mode, the driving system stops at a position which corresponds with the previous copying condition setting. Thus, wasteful operation of the driving system is eliminated.

Title: Adsorbent for pyrogen
Inventor: HIRAYAMA CHUICHI
IPC: B01J20/26
Filed: 1987-11-10
Abstract: PURPOSE:To increase a selective adsorption power of an adsorbent for pyrogen and to make a removal of pyrogen easy, by forming a pyrogen adsorbent prepared by combining an imidazole derivative with a carrier made of spherical particles of polyamino acid. CONSTITUTION:A pyrogen adsorbent is formed by combining spherical particles of polyamino acid with an imidazole derivative through a spacer containing acid-amide bond. Concretely speaking, in case of using the spherical particles at least partly containing glutamic acid or aspartic acid, the aimed pyrogen adsorbent is obtained by combining the imidazole derivative with the particles directly or through a spacer having carboxyl and amino groups. The obtained pyrogen adsorbent has an excellent reactivity with the pyrogen, and it is possible to carry out an operation of removing pyrogen in a short time by using this adsorbent, because it is hard and stable.

IPC: H01H47/00
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To provide a load control system wherein the so called momentary switch can be used and thereby handling becomes easy. SOLUTION: A switching relay winding L1 of a control device 3 is connected to a remote control transformer 2 through an outside contact part 4.

When the outside contact part 4 is turned off and the swiching contact r x returns to x side, a feeding line to the relay winding L0 is formed and the remote control relay 1 is held by itself. Thereby, a momentary switch can be used and handling becomes easy.

Title: Display method for size value of drawing
Inventor: UMEDA ISAO
IPC: G06F17/50
Filed: 1996-10-28
Abstract: PROBLEM TO BE SOLVED: To shorten the time needed to set a cursor on a ruled line and to prevent a size value from being unset owing to forgetful nonsetting of the cursor on the ruled line by automatically displaying all size values in the X-axial direction and Y-axial direction of a ruled line from a reference surface at specified positions. SOLUTION: A 1st ruled line 7 as the reference surface of the X axis is specified and stored. Positions from the said 1st ruled line 7 to ruled lines 7 to 10 perpendicular to the X axis are calculated and size values are displayed. Then a 5th ruled line as the reference surface of the Y-axial direction is specified and stored. Then positions from the 5th ruled line 11 to ruled lines 11 to 14 perpendicular to the Y axis are calculated and size values are displayed. Consequently, even when a figure consists of many ruled lines and is complicated or when a figure is large, only size reference surfaces and size value display positions need to be specified, so operations for enlarging and reducing planes are reduced and the efficiency of a plotting time is good.  Further, the size values of the object ruled lines are all displayed automatically, so the possibility of a misentry is eliminated.

Title: Air conditioner
Inventor: ARIMA TAKAFUMI
IPC: F24F11/04
Filed: 1989-11-01
Abstract: PURPOSE:To greatly relieve user's unpleasant feelings caused by an outlet air volume and an air blow noise and make the air volume and noise agreeable by providing a fluctuation mechanism for fluctuating the outlet air volume with time so as to have an 1/f spectrum on the basis of a signal released from a fluctuation signal generating means. CONSTITUTION:When a small air volume setting button 13 is depressed at an A point of time, a signal from a small air volume setting circuit 11 is outputted into a blower driving circuit 3 because the switch of a change-over circuit 12 is switched to a terminal 21b. Consequently, an outlet air volume is reduced, and the reduced outlet of the small air volume is fluctuated with time according to an 1/f fluctuation control. More particularly, an 1/f fluctuation function works at the same time as the small air volume outlet function works in the small air volume setting circuit 11 because a signal whose power spectrum is in inverse proportion to a frequency is added to the signal indicated by a broken line. As a result, an operation noise that is offensive to the ear can be suppressed.
