Abstract: PURPOSE:To obtain an easy retrieval system close to the binary search in terms of capability and close to the sequential search in terms of the system by checking records from the head of a history information file at plural number of intervals so as to apply the processing to detect the history information write position at system stop. CONSTITUTION:A message given from a terminal equipment is given to a DB/DC via a communication controller to decide and start a UAP for job processing by a reception message. In requesting the updating of the data base to a DB/DC, updating history is outputted to a DASD of history information simultaneously with the updating and outputs a reply message to a terminal equipment. The capacity of the DASD storing the history information is given in advance as a write enable record number, a record number (n) to be read and skipped is found based on the value, one record read and n-record skip are continued and the latest record is obtained by comparing the record number of the read record.

Title: Apparatus for detecting concentration of dust
Inventor: ITO YOZO
IPC: G01N21/53
Filed: 1984-11-26
Abstract: PURPOSE:To accurately detect the concn. of dust by keeping the amount of air supplied to a dust detector almost contact by absorbing the variation in the flow speed or static pressure of a dust-containing air stream by the increase or decrease in the amount of air leaked from the open part of an interference chamber. CONSTITUTION:If the clogging degree of a filter 1 becomes high, the static pressure at the opening end of a suction pipe 5 becomes slightly high. The variation in a flow speed or static pressure exerts effect on the sucking amount of air by a fist suction fan 11 but the fan 11 always sucks air in an amount equal to or more than that of air to be supplied to a dust detector 12 and allows excessive air to leak from an opening 13 in an interference chamber 10 and the variation in sucked air due to the variation in the air stream within an exhaust unit 2 is absorbed by the increase the decrease in the amount of air leaked from the opening 13 and the pressure in the interference chamber 10 becomes almost constant. Therefore, a constant amount of air is supplied to the detector 12 by the steady rotation of a second suction fan 18. By this method, the amount of sampled air supplied to the detector 12 is always kept constant at the time of the variation in the flow speed of dust-containing air and the concn. of dust can be accurately detected.

Title: Device for inducing frequency of brain wave
Inventor: FUJITA SHUZO
IPC: A61M21/02
Filed: 1987-10-04
Abstract: PURPOSE:To induce a brain wave to a frequency synchronized with a beat frequency, by generating two magnetic fields with different frequencies and by making a brain feel the frequency difference of the two magnetic fields as a beat generated at the crossing of the fields. CONSTITUTION:A signal generated at a transmission circuit F1 is sent to a coil L1 via a variable resistor VR1 for adjusting an output and then via a power amplification circuit A1 so as to generate a magnetic field at the coil L1. Another signal generated at a transmission circuit F2 is sent to a coil L2 via a variable resistor VR4 for adjusting an output and then via a power amplification circuit A2 so as to generate a magnetic field at the coil L2. The signal generated at the circuit F2 is set to have 4-30Hz of frequency difference from the signal generated at the circuit F1 with variable resistors VR2 and VR3 for setting a frequency. A beat is generated only at the crossing of the two magnetic fields respectively generated at the coils L1 and L2, and thereby a brain wave is induced to alpha-wave or theta-wave, which has a frequency synchronized to that of the beat. The generating position of the beat is controlled by changing the positions of the coils attached to a head and varying the diameters of the coils, the turn numbers and the intensity of the signals. The brain wave is thus quite naturally induced to alpha-wave or theta-wave.
