Title: Control of density of last printing of printer
Inventor: YOTSUTSUKA KOUSUKE
IPC: B41F33/10
Filed: 1985-08-27
Abstract: PURPOSE:To permit printing to be finished without producing useless paper while reducing the amount of residual ink on the transfer cylinder by a method in which when printing on the page preceding the final page is ended, an inking roller is separated from the transfer cylinder. CONSTITUTION:At a time when printing on the page with a paper number (set paper number-1) is ended, a inking roller 7a is separated from a plate cylinder 3. While printing is continued, at a time when the cylinder 3 is about half-turned, the cylinder 3 is separated from blanket cylinder 2. It follows thus that a small amounts of ink only is left on the plate wound around the cylinder 3. In this case, since the main flow of ink for printing the final page is similar to that during a regular printing made, printing for the final page can be performed with the same ink density as that of a regular printing, thus avoiding the production of useless paper.

Title: Low pressure mercuric vapor electric-discharge lamp
Inventor: ITO HIDENORI
IPC: H01J61/28
Filed: 1984-09-10
Abstract: PURPOSE:To prevent any decrease in the luminous efficiency of a low pressure mercuric vapor electric-discharge lamp and cause the entire outer tube to homogeneously emit intense light over a long time by installing an amalgam for controlling the internal mercuric vapor pressure of the inner tubes, restricting the discharge path, in the inner tubes. CONSTITUTION:Inner tubes 5 and 5 restricts the shape of the discharge path formed between electrodes 8 and 8 to a shape formed by arranging two U- shapes. Light from the inner tubes 5 and 5 is emitted outward through an outer tube 1. Outwardly extending thin pipes 10 and 10 are airtightly fused to a stem 2. And, in the thin pipes 10 and 10, an amalgam 11 for restricting the internal mercuric vapor pressure of the inner tubes 5 and 5 is installed. Because of the above structure, since mercury is successively supplied into the inner tubes 5 and 5 in which the density of mercuric atoms decreases during lighting, the difference between the densities of mercuric atoms in the inner tubes 5 and 5 in the outer tube 1 is almost prevented. Consequently, it is possible to restrict the optimum operation temperature to the level determined by the coldest temperature of the outer tube 1.

IPC: H03K17/56
Filed: 1987-07-28
Abstract: PURPOSE:To quicken the falling of an output signal by detecting a transient current caused due to parasitic capacitance of a bipolar transistor(TR) caused at the time of rising and providing a TR falling its output signal in response thereto. CONSTITUTION:A transient current Ipass flowing through a parasitic capacitor CCB at the time of rising and only at transient state is detected by a forward internal resistor of a diode 18 and fed to a TR 19. Thus, the TR 19 is turned on, a current Idis flows to the ground and the potential at an output terminal OUT goes immediately to a low level together with a TR 17 turned on simultaneously. Then an output signal is kept low by the ON-state of a 2nd bipolar TR 17 and the ON-state of the MOS TR 15 with a 2nd MOS gate circuit 21 turned on thereby increasing the falling responsiveness considerably. Thus, the transient current flowing uselessly for the charging/discharging of the CCB of a 1st bipolar TR 16 is utilized effectively to improve the performance of the logic circuit.

IPC: H01L29/786
Filed: 1981-11-26
Abstract: PURPOSE:To increase dielectric resistance, and to reduce leakage by using a nitride film as a gate insulating film when the MOSFET is formed onto polysilicon shaped onto an insulating layer. CONSTITUTION:An SiO2 film 22 is formed onto an Si substrate 21, and a P type polysilicon layer 24 and an N type polysilicon layer 23 are shaped onto the film 22. The MOSFETs are molded to respective layer, but the nitride films are adopted as the gate insulating films 25 at that time. The thickness of the films is made approximately 200-1,000Angstrom , and the films can be manufactured through a terminal nitriding method, a plasma growth method, etc. Accordingly, since projections are difficult to be shaped to the surfaces of the polysilicon, the dielectric resistance of gates is increased, and leakage is also reduced. Said nitride films are also effective when the polysilicon is directly formed to insulating substrate itself.
