Title: Measuring device for charge amount of charged particles
Inventor: MASUDA SENICHI
IPC: G01R29/24
Filed: 1982-10-30
Abstract: PURPOSE:To measure the charge amount of particles floating in the air and to take the measurement even when particle density is low by providing a high voltage power source connected to an electrode part supported by an insulating material at an interval so as to apply a high voltage to the electrode part and a particle counter which counts particles in the air from the electrode part. CONSTITUTION:When charged particles in the air come to between an inner cylindrical electrode 5 and an outer cylindrical electrode 8 through an entrance pipe 13, Coulomb force is generated by a high voltage applied between both electrodes to capture the particles to an electrode having opposite polarity, but the degree depends upon an air flow speed V or sampling attraction amount Q, the distance (distance) of the power source, the applied voltage V, particle size Dp, and the charge amount (n) of particles. For this purpose, when the rate of the number of particles passed through an electrode part 1 is counted by the particle counter 3 with regard to the particle size while the applied voltage V is varied, the graph shown in the figure is obtained. The applied voltage V determined by extrapolation, i.e. the dotted line is found from the figure and the charge amount of particles is measured by an equation.

IPC: G11B21/10
Filed: 1987-07-31
Abstract: PURPOSE:To reduce the number of parts and to miniaturize the titled device by using a pulse generated from a rotary motor as a timing signal for correcting and eccentricity. CONSTITUTION:A CPU 23 makes the polarity of eccentricity correcting data into a reversed polarity in accordance with the timing signal from a DMA timing circuit 31, reads them, and the read data are supplied to a tracking control circuit 16 through a D/A converter 22. That is to say, the eccentricity correcting data on a memory 24 are outputted to the D/A converter 22 for the edges of the switching of a sector. Thus, an output from the D/A converter is sent to the tracking control circuit 16 and a bias current is given so that an objective lens 6 always acts matching with an eccentricity form. Thus, by using the pulse generated from the rotary motor as the timing signal for correcting the eccentricity, without providing a detector such as a rotary encoder for the rotation axis of the rotary motor, the timing signal of the eccentricity correction can be generated, the number of the parts can be reduced, and the titled device can be easily miniaturized.

Title: Combustion control device for boiler
Inventor: MOROHOSHI MASAO
IPC: F22B35/00
Filed: 1984-09-17
Abstract: PURPOSE:To restrict a useless fuel consumption by a method wherein the scale of the degree of opening of a fuel adjusting valve for the combustion in a boiler is varied when the load is decreased less than the desired value and when a light load is applied, it shows a range of proportional control. CONSTITUTION:When an appropriate load is applied, steam pressure is controlled proportionally to a desired value by a pressure converter 14. When the load is reduced, the steam pressure is increased up to the OFF operating position of a pressure switch 19. A combustion safety control device 8 terminates the combustion at once when OFF operation is sensed. The steam pressure is decreased and gradually reached to ON operating point of the pressure switch 19. CPU23 counts the time t0 starting from OFF operation to ON operation. The combustion control device 20 changes over a scale converter 21 to narrow the driving range of a control motor 15 when the value t0 is higher than the desired value T0 and then a scale of degree of opening of the proportional valve 17 is varied to a lower value. When the combustion safety control device 8 detects ON operation of the pressure switch 19 and the combustion is carried out again, the steam pressure is proportionally controlled with a pressure set value of the pressure converter 14.

Title: Grinding spped adjusting device in grinding device
Inventor: YABUNO SADAO
IPC: B24B47/18
Filed: 1983-10-18
Abstract: PURPOSE:To always maintain the grinding accuracy constant irrespective of abrasion of a grindstone, by detecting a decrease in the diameter of an grinding element such as, for example, a grindstone so that the rotational speed of the grinding element is increased in accordance with the decrease of the diameter. CONSTITUTION:With repetitions of grinding operations a grindstone 3 is worn so that its diameter is gradually decreased. In a reflective type light optical sensor 6 in a detecting device 7, by checking that which one of light illuminating elements receives light from a light emitting element after reflected by the grindstone 3, the decreasing amount of the diameter of the grindstone may be known. Further, the amount of abrasion detected by a detecting device 7 is fed in the form of an electrical signal S to a control circuit 8. When a signal indicating a decrease in the diameter of the grindstone 3 is fed, the frequency of power supply is increased so that the rotational speed of a motor is increased. Accordingly, the peripheral speed of the grindstone increases by an amount corresponding to the decreasing amount of the diameter of the grindstone 3, and therefore, the contact area between a raw material 2 and the grindstone 3 per unit time may be maintained equal to that before abrasion so that it is possible to prevent the grinding accuraty from lowering.

Abstract: PURPOSE:To obtain a stable phase synchronizing oscillation state by a method wherein the oscillation starting current values of the semiconductor laser elements which are positioned closest to a light emitting region among the semiconductor laser elements in nonlight-emitting regions are larger than those of semiconductor laser elements in the light emitting region. CONSTITUTION:A plurality of semiconductor laser elements are formed on a semiconductor substrate 1 with a same interval and, among a plurality of the semiconductor laser elements, a predetermined number of the laser elements in a middle part constitute the light emitting region 5 of a semiconductor laser array device and the semiconductor laser elements provided on both the sides of the light emitting region 5 constitute the non-light-emitting regions of the semiconductor laser array device. In the semiconductor laser array device, at least the semiconductor laser elements which are positioned closest to the light emitting region among the semiconductor laser elements in the non-light-emitting regions are given oscillation starting current values larger than those of the semiconductor laser elements in the light emitting region 5. Therefore, even if a lateral leakage current is induced, the semiconductor laser elements in the non-light-emitting regions do not start the oscillation and only the semiconductor laser elements in the light emitting region 5 are made to oscillate. With this constitution, the oscillation mode of a stable and uniform phase synchronizing state can be obtained.

Abstract: PURPOSE:To reduce reflected light by a method wherein, when a resist is coated after a transparent thin film has been formed on a thin film composed of aluminum, a specific relationship is set among a thickness of the transparent thin film, a refractive index of the transparent thin film and the resist and an exposure wavelength. CONSTITUTION:A silicon single-crystal wafer is coated with a photoresist. The photoresist is exposed to light, developed and patterned; it is etched to form a substrate 1. An aluminum thin film 2, a silicon oxide film as an antireflection film 5 and a photoresist 3 are deposited on it. During this process, a relationship of 2nd=mlambda (where m is an integer) is set among a film thickness (d) of the antireflection film 5, a refractive index (n) of the antireflection film 5 and the resist 3 and an exposure wavelength lambda. Thereby, it is possible to prevent a reflection, and the resist 3 on the uneven aluminum thin film 2 can be patterned accurately without being influenced by a reflection from its substratum and by a stepped structure.
