Title: Duct type air conditioner
Inventor: FUKUSHIMA AKIO
IPC: F24F11/76
Filed: 1989-12-14
Abstract: PURPOSE:To carry out air conditioning for an individual room to be air conditioned at thermal load which fails to exceed the capacity control limit for heat supply equipment by installing an air volume set point station setter which sets a specified small air volume when air conditioning is suspended while a too small air volume signal is being transmitted from a total air volume detection means. CONSTITUTION:In the case when the thermal load of a room 8 to be air conditioned is small and a supply air volume is small, it is detected by a total air volume detection means 23 so that a too small air volume signal may be output. Responding with the output of the too small air volume signal, an air volume set point station setter 21 of the air conditioned room 8, which has suspended its air conditioning operation, sets a target air volume to a very small value. Therefore, the supply air volume is increased so that excess heating value generated by the lack of capacity control of heating supply equipment 4 may be dispersed to the air conditioned room 8 which has suspended its air conditioning operation and hence requires no air conditioning operation, thereby continuing the air conditioning operation within a capacity control range of the heating supply equipment 4. This construction makes it possible to provide a duct type air conditioner capable of performing separate air conditioning operation even for the air conditioned room 8 whose thermal load is small and below the control limit of the heating supply equipment 4.

Title: Light transmission type yellow toner
Inventor: NISHIGUCHI TOSHIHIKO
IPC: C08F8/34
Filed: 1987-12-21
Abstract: PURPOSE:To obtain a yellow toner which has sufficient light transparency and distinct colors even when transferred to a light transparent sheet by incorporating a polymer produced by bringing the chain micromolecule having a reactive substituent in the side chain and a specific rhodanine deriv. into reaction as a coloring component into the toner. CONSTITUTION:The polymer produced by bringing the chain macromolecule having the reactive substituent in the side chain and the rhodanine deriv. expressed by formula I into reaction is incorporated as the coloring component into the light transmission type yellow toner. In formula I, B denotes the substituent having reactivity; C denotes a divalent org. group; R1 denotes an alkyl group of 1-6C, hydroxyl group; P denotes 0 or 1. If the polymer having such rhodanine deriv. in the side chain is used, the polymer itself is the yellow polymer having excellent light transparency and, therefore, the toner of the light transmission type is obtained by merely granulating the polymer. The yellow toner of the distinct color having the excellent light transparency is thereby obtd. by transferring the developed image onto the light transparent sheet.

Title: Image forming device
Inventor: KUBO TAKAHIRO
IPC: G03G15/20
Filed: 1993-12-22
Abstract: PURPOSE:To prevent irregularities in an unfixed image even if carrying speed at the time of transferring a transfer material is different from fixing speed by carrying the transfer material to a transfer position again after the completion of the transfer, so as to vary the rotational speed of a carrier, in the case where the fixing speed is made lower. CONSTITUTION:When the fixing speed is reduced, for instance, in the second surface of both surfaces, a paper sheet carried up to a transfer nip part is not separated even if its leading edge part is carried up to a separating part, but the rotation is executed as the paper is carried on a transfer drum 5, while the toner of the final color is transferred. After the transfer of the final color has been entirely completed, the rotational speed of the transfer drum 5 and a photoreceptor 1 are reduced. Then, the paper is separated simultaneously with the first surface with timing that the leading edge of the paper reaches the separating part again. At this time, cleaning devices 14a and 14b come into contact with the surface of a carrying sheet with the timing that a part after the leading edge of the paper exists reaches a cleaning part, during the same period as the separation, to clean the part after the paper exists. Thus, color smearing is not caused and an adverse effect by the transfer sticking of oil is eliminated.

Abstract: PROBLEM TO BE SOLVED: To dispense with a frequency converter and a frequency divider to permit a simple structure by adding phase value respectively determined from a code bit of each digital signal or a signal adding or dividing a square value of the same signal. SOLUTION: A digital signal processing part 3-9 branches digital signals i(t), q(t) at points c, d in two and a squares 3-1, 3-2 create signals i2(t), q2(t) from each one of their branch signals. An adder 3-3 makes them to a signal i2(t)+q2(t), and a divider 3-4 divides a signal from the squarer 3-1 by the signal i2(t)+q2(t) to create a signal i2(t)/ i2(t)+q2(t)}, and convert it to a corresponding phase value with a square amplifier and phase converter 3-5. Regarding other signals of the branch signals, a code bit detector 3-6 extracts one from among four kinds of code bit patterns and a code bit and phase converter 3-7 outputs phase value corresponding to the pattern. A phase of a receiving sine wave electric signal can be detected by adding the output and an output of the phase converter 3-5 at adder 3-8.

Title: Coincidence oscillator
Inventor: MIZUNUMA YASUYUKI
IPC: H03B5/18
Filed: 1988-12-22
Abstract: PURPOSE:To realize a coincidence oscillator at a low phase noise over the broad band by making the impedance of a matching circuit lower than the terminal impedance. CONSTITUTION:On one main surface of a GGG substrate 1, MIC lines M1, M3, M4 and M5 consisting of Au films are formed. A stub S' is formed on the MIC line M1. The impedance of the MIC line M1 constituting the matching circuit is set at a value lower than that of a terminal impedance Z0 (=50OMEGA), for example, at 20 to 30OMEGA. Thus, the load of a coincidence oscillator (YTO) using ferromagnetic resonance becomes optimal, and a frequency locus turns counter-clockwise. For this reason, the YTO at the low phase noise lower than -96 dBc/Hz can be realized over the broad band, for example, in a range 11 to 14GHz.

IPC: H03K5/08
Filed: 1989-12-14
Abstract: PURPOSE:To comparate two inputs with a prescribed hysteresis width by using a capacitor for forming a feedback circuit so as to eliminate the need for a smoothing filter. CONSTITUTION:Let the voltages applied to input terminals IN1, IN2 be denoted by V1, V2 respectively and the output voltage of an inverter 2 by V0 (and output voltages of H, L levels by VOH, VOL respectively), then since one voltage across the capacitors C1, C2 is V1, an inverted input terminal voltage V<+> of an operational amplifier 1 is expressed in equation I. When the comparator output changes from VOH to VOL or from VOL to VOH respectively, equations II, III are yielded from the equation I. When the inequalities II, III are replaced into equations, the hysteresis width VTH of the comparator is obtained as equation IV. The hysteresis width is expressed by the equation replacing two resistive constants deciding the hysteresis width of an analog hysteresis comparator circuit subject to resistance voltage division into the capacitances C2, C1.
