Title: Data processing method for mass spectrometry
Inventor: SHIMOMURA MANABU
IPC: G06F7/00
Filed: 1992-04-30
Abstract: PURPOSE:To set automatically the peak select level of a mass spectrum by taking up a certain portion of those spectral peaks, which are sampled without specimen, in the sequence from the stronger one, and setting the select level to the strength of the min. peak at the time. CONSTITUTION:A CPU 6 gives the data corresponding to the select level 0 to a D/A converter 4 and takes into an inner memory 7 the mass spectrum data in a specified mass range by driving a mass spectrometer. Because therein the input of the D/A converter 4 is zero and the set level of a level selector 3 is zero, the data taken in includes all peaks and noises which form the background. The CPU 6 determines peaks from the taken-in data and takes the integer part A by multiplying the number of peaks with P/100, where P is the percentage registered in CPU which represents what percent is to be taken among all spectral peaks. The A'th peak in the magnitude of strength is sought being reckoned from the strongest, and the data is given to the D/A converter 4 so that the sought strength becomes the select level, and the select level of the selector 3 is set.

Abstract: PURPOSE: To secure the decision for the effective or ineffective page code by providing the independent page detection part at the right and left pages each and then delivering the coincidence signal if the coincidence is secured for the codes through comparison of the output of the page detection parts.  
     CONSTITUTION: The output of left-side page detection part 4 is sent to page encoder 5 to be supplied to comparator circuit 9 along with the output of right-side page detection part 8. Then the coincidence signal is delivered outside by the right and left page codes and via driver 3. Now in case both the both pages are not lifted up, the coincidence is secured for the output codes between parts 4 and 8. Thus circuit 9 delivers the coincidence signal. In case the page alignment is in the course of execution, circuit 9 delivers no coincidence signal since the output codes differ between the both page detection parts. In such way, the decision is possible for the effective or ineffective page codes.

Title: Heating device
Inventor: TANAKA NAOKI
IPC: F24D12/00
Filed: 1983-07-29
Abstract: PURPOSE:To enable control of a flow rate of heating medium to a condenser into a proper amount even if the temperature of the open air is decreased, by a method wherein a steam compression type heating device is constituted such that a compressor, a condenser, a pressure reducing device, and a vaporizer are coupled with each other, in order as noted, to circulate the heating medium, and the steam of the heating medium is liquefied by said condenser to emit the heat. CONSTITUTION:When, with a switch 8 closed, a coolant liquid 14 is heated by a heat generating substance 6, coolant gas gathers in a gas phase part 13 to increase steam density. As a result, a pressure within a heater 5 becomes higher than a pressure within a condenser 2, and since a check valve 12 on the feed-in side is located, coolant gas flows into the condenser 2 from the gas phase part 13 of a heater 6 through a feed-out piping 9 and a check valve 11 on the feed- out side. When, after a given time has elapsed, the switch 8 is brought to an ON-state, the interior of the heater 5 is gradually cooled, and when the temperature at the interior of the heater is decreased over the temperature at the inside of the condenser 2, a pressure therein is also decreased over that in the condenser 2. Thus, since the check valve 11 on the feed-out side is disposed on a piping 9 on the feed-out side, coolant liquid within the condenser 2 is returned to the heater 5 through the check valve 12 on the feed-in side. A heating action is rendered effective or ineffective through proper control of opening and closing of the switch 8, and this permits supplement of a flow rate of coolant by means of a heating device 15, and enables proper maintenance of a flow rate of coolant within the condenser 2.

Title: Ventilation control unit for ventilation duct
Inventor: HONMA SHIYOUJI
IPC: G05D16/20
Filed: 1979-10-31
Abstract: PURPOSE: To enable good control and energy saving by switching valve opening control to pressure raising conrol according to the magnitude of load variation.  
     CONSTITUTION: When a detector 6 installed in a ventilation duct 2 is detecting relatively small load variation, valve opening control (control mode 1) with a valve 7 is made by the first controller 9. When the  load variation is too great to be followed by damper control only, the control is switched by a control mode change- over mechanism 12 to a control mode that uses rotational frequency control of a booster 8. After following the load variation, the control is returned to the valve opening control. Thus, by using highly responsive valve opening control and energy- saving pressure raising control cooperatively, control against load variation can be performed with high responsiveness. Moreover, energy loss due to pressure loss can be prevented and energy-saving can be effected.
