IPC: H03F3/193
Filed: 1999-06-15
Abstract: PROBLEM TO BE SOLVED: To keep linearity, even for large input by connecting the source of a 1st MOSFET to one of both ends of a 1st resistance, connecting the source of a 2nd MOSFET to the drain of the 1st MOSFET, connecting an output terminal to the drain of the 2nd MOSFET and connecting a passive element between the drain of the 2nd MOSFET and the 2nd voltage respectively.

Then the voltage Vds1 becomes such that Vds1=Vsg1-Vgs2. Under such conditions, the voltage Vds1 can be decided by the ratios set among Wg1, Wg2, Lg1 and Lg2 to always secure operation in a linear region, when the gate length Lg1 and Lg2 and the gate width Wg1 and Wg2 are defined for both MOSFET M1 and M2 respectively.

Title: Electrophotographic copying machine
Inventor: IKO MITSUTOSHI
IPC: G03B27/52
Filed: 1986-07-17
Abstract: PURPOSE:To attain editing fully controlled at its density by dividing a copying area into plural areas and optionally changing the quantity of exposure in each divided area to optionally change copying density. CONSTITUTION:A copy with different density can be obtained by changing the quantity of exposure at different parts along the scanning direction of an original M. In case of an original M including both a character part (a) and a photograph part (b), exposure is reduced on the character part (a) by increasing the pulse rate of a stepping motor 5 and the exposure is increased on the photographing part (b) by reducing the pulse rate of the stepping motor 5 to set up proper copying density in respective parts. Thus, the density is changed in plural areas obtained by dividing the original M.

Title: Echo control system
Inventor: YABUTA HIDETO
IPC: H04L47/20
Filed: 1990-06-26
Abstract: PURPOSE:To improve serviceability for terminal equipment by surely returning all the characters transmitted from the terminal equipment as echoes. CONSTITUTION:An input regulation signal transmission means 200 detects the fact that an echo buffer 61 is filled with the character Ci, and transmits an input regulation signal to prohibit the transmission of the character Ci to the terminal equipment 1. A spare buffer 62 stores the character Ci arriving until the transmission from the terminal equipment 1 is stopped after the input regulation signal transmission means 200 transmits the input regulation signal. An input regulation cancelling signal transmission means 300 cancels the transmission of the character Ci to the terminal equipment 1 setting the characters Ci stored in the echo buffer 61 and the spare buffer 62 as the echoes Ce in a state where the input regulation signal transmission means 200 transmits the input regulation signal.

Abstract: PURPOSE:To provide a low-yield ratio, high-tension hot-rolled steel plate having excellent workability by treating a specified composition steel at a specified heating temperature and cooling rate. CONSTITUTION:A steel composition consists of: C: 0.01-0.12%, Si: below 1.0%, Mn: 1.0-3.0%, Cr: 0.2-2.0%, particulary Mn+Cr: 2.5-4.0%, SolAl: 0.020- 0.100%, P: below 0.015%, S: below 0.010%, and the remaining Fe and unavoidable impurities. The steel is hot rolled at a finishing temperature over Ar3 transformation point, then is wound at a temperature below 700 deg.C. After cooling and pickling, the hot-rolled steel plate is heated and soaked in annealing in the range over Ac1 transformation point and below Ac3 transformation point, and is followed by a batch annealing to 400 deg.C at a mean cooling rate of 10-200 deg.C/hr.

Title: Manufacture of solar heat collector
Inventor: NAKAYAMA TAKAFUMI
IPC: F24S10/70
Filed: 1982-09-27
Abstract: PURPOSE:To prevent the outer tube from sustaining damages when heat collector is inserted into the outer tube of the heat collector by decreasing the diameter of a resilient support less than the inner diameter of the outer tube, melting the bonding agent by heating, after inserting the heat collector into the outer tube by maintaining the diameter decreased state by the adhesion of the bonding agent so as to press-fit the support onto the inner surface of the outer tube. CONSTITUTION:Before inserting a heat collector 2 into an outer tube 1 made of glass, the diameter of a spring member 3 is decreased less than the inside diameter of the outer tube 1 as shown in Fig. (a), and a bonding agent 6 consisting of a solder having a melting point of 180-220 deg.C, for example, is applied to the end part of the spring member 3, and melt-hardened to maintain this diameter decreased state. Thereafter, as shown in Fig. (b), the heat collector 2 is inserted up to a predetermined position. In this inserting step, the contact between the spring member 4 and the outer tube 1 is little, and the damage of the outer tube are decreased. When the bonding agent 6 is heated to approximately 100 deg.C (since the spring member 3 has an expanding force, it is not required to completely melt the bonding agent), the spring member 4 expands by the resilient force of the spring member itself and is press-fitted to the inner face of the outer tube 1 as shown in Fig. (c), and the heat collector 2 is fixed to a predetermined position of the outer tube 1.
