Title: Magnetic disk memory device
Inventor: HIROSE TAKESHI
IPC: G11B5/09
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To allow the S/N ratio to be improved by providing a bias circuit with a resistance value sufficiently larger than that of an MR head, and performing switching-control for first and second resistance elements which provide a first potential to an interconnection point, a first constant current source MOSFET that supplies a bias current to these elements, and a second MOSFET that supplies another bias current corresponding to the bias current. SOLUTION: In an MR head corresponding to another magnetic recording surface in which a readout signal is amplified by a read amplifier Amp and read out via a post amplifier and an output circuit, MOSFETs Q5, Q6 are set in the OFF condition so that no readout operation is performed. Since MOSFETs Q2, Q4 constituting a constant current are provided with resistor R2, R5 at their sources, respectively, their transconductance Gm as an amplifying element is lowered due to their negative feedback function. Accordingly, inductive gate noise components to be superposed over constant currents that are to be output from drains of the MOSFETs Q2, Q4 are made small.

Abstract: PURPOSE:To make light sensitivity excellent, by forming a transparent protective film so as to cover a photoelectric conversion element by evaporation, sputtering or the like, selecting the refractive index and the thickness of the transparent protective film, thereby controlling the reflectivity of incident light to the photoelectric conversion element. CONSTITUTION:In a close contact type image sensor, an output electrode 8, a photoelectric conversion film 9 comprising an amorphous silicon thin film, an insulating transparent electrode 10 comprising an amorphous SiC thin film and a transparent electrode 11 are formed on a glass substrate 7. A transparent protective film 12 comprising an SiO2 thin film is formed so as to cover those parts. The refractive indexes and the film thicknesses fo the electrodes 10 and 11 are selected so that the reflectivities become approximately the minimum values. The transparent protective film 12 is formed by evaporation, sputtering and the like at a film thickness so that the light reflectivity becomes approximately the minimum value. The refractive index is also selected so that the light reflectivity becomes approximately the minimum value. Thus the attenuation of the incident light to the photoelectric conversion film 9 becomes minute, and the light sensitivity of the sensor becomes excellent.

Title: Nox suppression three-step burning method
Inventor: SEKIGUCHI YOSHITOSHI
IPC: F23C99/00
Filed: 1982-04-27
Abstract: PURPOSE:To make it possible to suppress the quantity of soot and dust particularly in the case of using a heavy fuel in a high-load furnace or a small- size furnace by using an emulsified fuel as a secondary fuel. CONSTITUTION:Upon carrying out three-step combustion by successively disposing a primary burner 12, a secondary fuel nozzle 13 and a secondary air nozzle 14 on the rear stream side, an emulsified fuel prepared by mixing and agitating a fuel F and hot water W with each other by a mixer 22 as a fuel supplied to the secondary fuel nozzle 13, is used. Accordingly, the relation between the emulsification ratio of the secondary fuel and the quantity of soots and dirts generated upon the actual burning operation lies in that, as compared with the case where the entire fuel is emulsified, the increase in the heat loss can be suppressed, and a great suppression of the quantity of soot and dust generated becomes possible.

Title: One-button manipulation type automatic firing gas controller
Inventor: HIRATA TADAKI
IPC: F23Q9/12
Filed: 1985-04-04
Abstract: PURPOSE:To provide a one-button manipulation type automatic firing gas controller capable of increasing the safety without emission of an explosive sound or flowing-out of a raw gas by performing a series of operations by a main cam so that a safety valve and a pilot valve are opened at the time of a pushing-in operation through a single push rod, and a master valve is opened at the intermediate of the pushing-in return operation. CONSTITUTION:When a push rod 5 is pushed in a direction of arrow (a) by a push- button operation, a safety valve 8 is first pushed open by the tip end 5a of the push rod 5. At the same time, an operating member 13a of an ignition switch 13 is pushed by means of a switch cam 14. Further, since a pilot valve 10 cooperates with a push rod 15, a pilot valve port 17 is simultaneously opened, and a pilot is ignited. The pushed-in push button is again pushed in to be released, the push rod 5 returns in the original direction [arrow (b)] by the elastic force of a spring 5. Upon this occasion, a main cam 12 is actuated at the same time. However, upon this occasion, since a valve rod 11a is pushed by the operating port 12'' of a cam projection 12b, the master valve 11 is pushed open against a force exerted by a spring 15. Since the safety valve 8 keeps a valve open by the generation of a thermoelectromotive force, the main burner is ignited.

Title: Image reader
Inventor: HATAMURA JUNJI
IPC: H04N1/38
Filed: 1997-03-26
Abstract: PROBLEM TO BE SOLVED: To obtain fine picture data, even when a read original with a short width dimension is displayed or recorded. SOLUTION: When the width of a read original does not match with a scanning region (S3: YES), a CPU judges or not whether the width of the original is smaller than a half of the scanning area (S4). At the time of judging that the width is smaller than a half of the scanning reign (S4: YES), the CPU sets up (S5) a threshold level in which the width of a high level band on the whole scanning region is allocated to about 1/2. Then the CPU discriminates (S6) an image signal based on the set threshold level. Finally the CPU processes (S7) the image of the read original as data, based on the discriminated image signal. Thereby the image signal discriminated corresponding to the low level band of the threshold level is turned into a white image, so that the outside regions of both the sides of the original in the main scanning direction are turned to white images.
