Title: Circuit assembly to control push-pull stage of mos field- effect transistor
Inventor: KONRATSUDO BUAAGENZOONAA
IPC: H03K17/0812
Filed: 1994-06-15
Abstract: PURPOSE: To suppress both FET from being simultaneously conducted by providing an inhibiting circuit operating depending upon the gate voltage of the other FET at the gate of one FET constituting a push/pull stage. CONSTITUTION: A push/pull stage is composed of two power MOSFETQ1 ,2 constituting a high potential side driver(HSD) and a low potential side driver(LSD). Input voltages Ue1 ,2 are turned through time constants constituted of inter-gate/source capacity CGS1 ,2 and ohmic resistance R into gate voltages VG1 ,2 , and the conduction of the FETQ1 ,2 is controlled. An MOSFETQ3 continues conduction and prevents the gate of an HSDFETQ1 from being charged until the gate voltage VG2 of the LSDFETQ2 is sufficiently discharged through the time constant constituted of the inter-gate/source capacity CGS2 and the ohmic resistance R. An MOSFETQ4 prevents the gate of the FETQ2 from being charged until the gate voltage VG1 of the FETQ1 is sufficiently decreased.

Title: Low noise amplifying device
Inventor: KIYONO KIYOHARU
IPC: H04B15/00
Filed: 1990-05-22
Abstract: PURPOSE:To obtain a low noise characteristic even if only a transmitting wave is absorbed and a part of the transmitting wave leaks in by selecting a constant of a filter circuit so that a resonance frequency becomes a parallel resonance against a receiving wave, and a series resonance against the transmitting wave. CONSTITUTION:With regard to values of a resistance 6 for configuring a filter circuit 10, inductive elements 7, 8 and a capacitive element 9, values of the elements 7, 8 are determined by a prescribed operation so that the impedance which view a ground side from an A point by giving arbitrarily the value of the element 9 becomes infinite against a receiving wave, and becomes a resistance R against a transmitting wave. In such a way, the receiving wave received by an antenna is not influenced by the circuit 10, but the transmitting wave which leaks in by a reflection from the antenna, etc., is absorbed by the resistance 6of the circuit 10. As a result, saturation of a low noise amplifier caused by the transmitting wave can be avoided, and a low noise characteristic is obtained.

IPC: B29K81/00
Filed: 1986-06-11
Abstract: PURPOSE:To improve the adhesive property of the title film to a cooling roll, the flatness and the appearance of the same, by a method wherein, the film is nipped and cooled by the cooling roll, prepared in a temperature within a specified range, and a rubber roll provided with a specified rubber hardness. CONSTITUTION:The molten composition of heat resistant resin, whose glass transition tmeperature is 100 deg.C or higher, is extruded through the slit type die, such as T die or the like, then, is pulled down and cooled by a device constituted of a metallic roll and a rubber roll, which are pressed with each other. The temperature of the metallic roll is Tg-50-Tg-10 based on the glass transition temperature Tg of the composition. When the temperature is up to Tg-50, the adhesion of the title film to the metallic roll becomes ununiform and when the temperature exceeds Tg-10, cloudiness is generated some times. The hardness of the rubber roll achieves a certain effective adhesive property when it is 40-70 deg.C in rubber hardness Shore A while the hardness up to 40 degree is too soft and is not effective in actual use but when the hardness exceeds 7 deg.C, it is hard to absorb mechanical fluctuation and unevenness in thickness, wrinkles or the like may be generated readily.

Filed: 1978-10-31
Abstract: PURPOSE: To obtain the desired Zener voltage, by specifying post-diffusion substrate pull-out temperature when pn junction is formed by diffusing pentavalent phosphorus on Si substrate containing a high concentration trivalent impurity.  
     CONSTITUTION: Pentavalent phosphorus is diffused into p-type Si substrate doped with trivalent impurity, 9×10 19 atoms/cm 3  in concentration, and a region whose surface concentration is 3×10 21 atoms/cm 3  and whose depth is 10μm is formed and a pn junction is produced. Then, the substrate so construced is pulled out from the diffusion furnace. At this time, in reference to the relationship between the Zener voltage and the temperature at the time of pull-out which has been obtained in advance, the substrate is maintained at the neighborhood of its activation temperature. Subsequently, it is cooled, and when it has become the pull-out temperature corresponding to the desired Zener voltage, it is taken out and is cooled speedily, and thereby the Zener voltage is maintained. That is, use is made of the sheet resistance of the diffusion layer which changes with temperature and the variation in the concentration gradient of the junction accompanying this, and thereby the Zener voltage is set at the desired value.

Title: Resin composition for toner, its production and electrostatic charge image developing toner using the composition
Inventor: TAGAMI TOSHIO
IPC: C08L67/02
Filed: 1996-04-30
Abstract: PROBLEM TO BE SOLVED: To provide a resin composition for toner excellent in low-temp. fixability, excellent in offset preventing effect and with the developing characteristic, transferrability and fixability improved by incorporating a cross-linked diallyl phthalate resin into a linear polyester resin to form the composition. SOLUTION: A linear polyester resin as a low-temp. fixing component and a diallyl phthalate resin having >=2 functional allyl groups are heated and mixed, and the cross-linked diallyl phthalate resin is uniformly dispersed in the linear polyester resin composition. In this case, 10-40 pts.wt. of the crosslinked diaalyl phthalate resin is incorporated in 100 pts.wt. of the linear polyester resin. When <10 pts.wt. of the corss-linked diallyl phthalate resin is incorporated, the flowing temp. width based on the flow tester is not practically changed from that of the conventional low-m.p. polyester resin, and there are some cases when the non-offsetting property is not satisfied. When 40 pts.wt. is exceeded, a good non-offsetting property is secured but the lower limit of the fixing temp. is remarkably raised, and there are some cases when low-temp. fixability is not secured.

Abstract: PURPOSE:To prevent the generation of the irregularity of printing density at the time of continuous printing by variably controlling the current supply time of the heating element at every dot of a thermal recording head corresponding to the accumulation state of heat at every head when the image read by an image sensor is recorded. CONSTITUTION:In a converter circuit 6 controlling the current supply times of respective heating elements H1 - Hn', the charged voltages of capacitors C1 - Cn are discharged through resistors R1 - Rn and Rm1 - Rmn when analogue switches A1 - An are turned ON and the heat width at every one dot of a ther mal head 9 is determined by the discharge times of said capasitors. Therefore, the switches A1 - An are controlled by the signals SC1 - SCn from a control unit 1 and, for example, when the dots are continuously heated in the previous process of the present printing and the heat accumulation of the head is much, the switches A1 - An of said dots are turned ON and, contrarily, when heat is not accumulated, the switches A1 - An of the dots are turned OFF and the change of printing density generated in a dot unit by the accumulation of heat can be suppressed and the irregularity of printing density can be eliminated as a whole.

When  the back 6 is fixed, an elastic seal member 11 is fitted in the groove 12 of the  projection 8 of the back 6 and the back 6 is pushed into the middle 1. Then the  seal member 11, guided by the leading part 4, is turned round onto the upper  side of the projection 3 while being deformed, and is engaged therewith. Accordingly, the back 6 is surely fixed to the middle 1 even with low dimentional accuracy, without being fitted directly to the middle 1.
