Title: Frequency control method for crystal oscillator
Inventor: MORISAKO ISAMU
IPC: H03H9/19
Filed: 1996-11-28
Abstract: PROBLEM TO BE SOLVED: To provide a frequency control method for crystal oscillator with which frequency control is enabled at low cost without deviating the frequency of crystal oscillator. SOLUTION: A crystal oscillator 1 is set at the lower part of case 10. Ions are injected from an ion gun 16 toward an insulator 14 provided inside the case 10 and insulating particles are scattered from the insulator 14 by its collision energy and stuck on the surface of crystal oscillator 1. During this operation, the frequency of crystal oscillator 1 is measured by a frequency measuring part 30 and when it reaches a target frequency, the emission of ions from an ion gun 16 is stopped. The insulator 14 is inexpensive and the insulating particles stuck on the crystal oscillator 1 do not affect the capacitance of crystal oscillator.

IPC: F23C10/02
Filed: 1994-12-21
Abstract: PURPOSE: To equalize the release of NOx and the trapping of SO2 during the period under the full load conditions, by a method wherein air is passed into a bed in a furnace section in quantities sufficient to fluidize combustible particulate material formed on the bed and insufficient air to completely combust the material, and overfire air is passed into an overfire air plenum in quantities sufficient to completely combust the particulate material through a partition. CONSTITUTION: Particulate combustion material and adsorbent material in a furnace section 36 are fluidized as air from a plenum 56a passes upward through a plate 50. The quantity of air introduced into the furnace section 36 through a nozzle 52 is controlled to be less than the quantity of air necessary for the complete combustion of fuel particles. Overfire air, namely, secondary air is supplied to a plenum 38 through ducts 66 and 68 and then, air passes into the furnace section 36 through control dampers 34a and 34b via ducts 32a, 32b and 32c. Thus, the overfire air is supplied in the sufficiently controlled quantities to completely combust the material and to maintain the optimum stoichiometry and an upper furnace load.

Title: Method for driving active matrix type liquid crystal display device
Inventor: SHIRAISHI ATSUSHI
IPC: G09G3/36
Filed: 1993-12-17
Abstract: PURPOSE:To restrain the generation of a DC voltage to liquid crystal by data difference with a small-scale circuit and to prevent burning by setting the frequency of the readout address signal of a field memory to twice or more times as much as a value obtained by multiplying the field frequency by all the number of picture elements. CONSTITUTION:The value of the frequency of the readout address signal of the field memory 602 is set to twice or more times as much as the value obtained by multiplying the field frequency by all the number of the picture elements, one readout address of the field memory is finished during a vertical line term, and also the next readout address of the field memory is started after one address is finished, and display data writing is performed on each picture elements twice during one field term. The same data can be written in a state where they are divided into positive and negative polarities by making the driving frequency twice as much as the field frequency. Consequently, since a DC component is compensated by different polarity, the DC component of the voltage on both ends of the liquid crystal is prevented from being generated even in the case of displaying any kind of data.
