Title: Computing device for unburnt part in ash at coal-fired boiler
Inventor: KISHIKAWA TADAHIRO
IPC: F23N5/00
Filed: 1987-07-01
Abstract: PURPOSE:To improve efficiency in minimizing exhaust gas loss by a method wherein the amount of unburnt part in combustion ash is obtained by continuous computation in actual operation time and operation is carried out in reducing excess air as much as possible at all times. CONSTITUTION:Respective outputs of a computing element 6 for received heat amount of generated steam, a computing element 7 for fuel heat input, and a computing element 8 for boiler efficiency are fed into a computing element 9 for unburnt rate to obtain an unburnt rate. The output of the element 9, the changed amount of fuel 3, and an ash ratio 10 in fuel previously obtained are fed into a computing element 11 for the unburnt part in ash to obtain the unburnt part in combustion ash. The unburnt part in ash thus obtained becomes a bias 16 for setting a heat ratio suitably. The bias 16 is added to or subtracted from the valve of a setting device 17 for an air fuel ratio as the ratio of air to fuel in a bias from and fed into a device 20 for setting an air flow amount to keep the amount of the unburnt part in ash under a limited value. An excess air amount set by the device 20 is used to control the air flow amount 4.

Title: Improved suscepter
Inventor: ISURAERU BEINGURASU
IPC: H01L21/205
Filed: 1994-07-14
Abstract: PURPOSE: To provide a suscepter which receives and supports a substrate during working process in a substrate processing chamber. CONSTITUTION: A suscepter 40 is formed from a front surface, or an upper surface, in which a pocket 48 for receiving a substrate is formed. The pocket 48 has a floor 47 and, generally, an upright side surface. A circumscribing groove 54 is formed in the floor of the pocket 48, with its size determined so that the groove is present generally beyond the periphery of a substrate, when a substrate is received in the pocket 48. The upright side surface, together with the groove, acts so as to suppress a substrate processing gas from reaching the upper surface of the substrate. A single connecting groove is formed on floor of the pocket. When the substrate is received in the pocket, it rides on the top part of groove, so that a surface area on which the substrate rides is reduced.  As a result, after the process, the substrate is not stuck to the floor of the pocket 48, so that it is lifted up from the suscepter 40 without being damaged.

Title: Meter voltage amplifier circuit
Inventor: EJIMA NAOKI
IPC: G01R19/00
Filed: 1980-11-18
Abstract: PURPOSE:To make low voltage driving of a meter possible and improve temp. characteristics by connecting the emitter of a transistor to which the meter signal voltage is applied to the base of a transistor having complementary characteristics with said transistor. CONSTITUTION:The meter signal voltage applied to the input terminal IN1 connected to the base of a PNP transistor (TR) Q1 goes higher by the voltage between base and emitter and appears on the emitter side. This voltage further enters the base of a PNP transistor (TR) Q2 and collector current is so flowed that it goes lower by the voltage between base and emitter to provide emitter voltage. Now if it is assumed that the voltages between the bases and emitters of the TRs Q1 and Q2 are equal, the meter current IM is IM=Vin/R2. Thereby, the influence of the voltage between the emitters and bases of the TRs Q1, Q2 upon the deflection of the meter is obviated and the amplifier circuit having superior temp. characteristics is obtained.

Filed: 1995-06-29
Abstract: PURPOSE: To prevent the potential of an end part from being lowered in comparison with a central part and to prevent the density of an image from becoming high only at the end part by making the electrostatic charge width of an auxiliary electrostatic charge means wider than that of an electrostatic charge means. CONSTITUTION: The auxiliary electrostatic charger 15 and an electric discharge lamp 25 are provided at an identical place on the surface of a photoreceptor drum 4 by being superposed above and below in order to electrostatically charge the drum 4 and to expose the whole surface thereof at the same time. Before the drum 4 is primarily electrostatically charged, it is electrostatically charged by the charger 15 so that the polarity of the memory effect area thereof becomes identical to that of an electrostatic latent image formed thereon, that means, it becomes the negative polarity. Besides, the drum 4 is discharged and exposed by the lamp 25 at the same time. In such a case, the density of the end part of the image becomes high because the charger 15 is provided in order to eliminate the memory effect area.  However, it is prevented from becoming high by making the aperture width of the charger 15 in a longitudinal direction wider than that of a primary electrostatic charger 6.
