Title: Automatic ventilating device
Inventor: SHINOZAKI TOSHIYA
IPC: F24F7/007
Filed: 1988-04-27
Abstract: PURPOSE:To start the operation at the same time as the start of cooking and automatically switch the rate of ventilation in the event of flame failure or fire by providing an ultraviolet ray sensor, a gas sensor and a temperature sensor, and controlling a fan motor by means of outputs from respective sensors. CONSTITUTION:A microcomputer 7 reads the output from a pulse counter 4, and, if the ultraviolet ray measurement value (PC) is above a set limit (N), determines that the ultraviolet ray are being emitted from the flame of gas stove, whereupon a ventilating fan is started. When gas sensor 1 detects the presence of smoke, its output level (SEN1) is increased to control the air delivery rate in accordance the value of output ratio (SC). Should flame failure occur, PC becomes zero and SEN1 significantly increased. As a result, the microcomputer 7 actuates a motor control circuit 10 using the maximum control quantity. In the event of fire, PC is rapidly increased to become greater than the second limit (N') which is far greater than N. The differential temperature (TC) becomes greater than a third temperature differential reference value (THD2') which is very large. Because of this, the equations PC>=N' and TC>=TDH2' are met, and so the ventilating fan is stopped.

Title: Device and method for recording/reproducing optical disk
Inventor: UEKI YASUHIRO
IPC: G11B7/004
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To shorten an access time until the data are really reproduced from instruction of reproducing operation by using angular velocity constant information of a wobble and rotation driving an optical disk at a constant angular velocity. SOLUTION: While reproducing the optical disk, an FG signal from a non- wobble detection circuit 52 and a timing signal from an address mark extraction filter 51 are supplied to a wobble joint period detection circuit 55. The wobble joint period detection circuit 55 selectively outputs either one between these FG signal and timing signal, or both signals to a control circuit 38 through a switch 54 as a speed signal. Thus, the control circuit 38 CAV(constant angular velocity) rotation controls a spindle motor 31. Particularly, when angular velocity information is much in the outer periphery of the optical disk 11, an address detection circuit 53 or the control circuit 38 judges by a present address signal, etc., and constitutes a one round loop so that this frequency becomes constant.

Title: Inspection of blood depending on light emission
Inventor: KANEDA HISASHI
IPC: A61B5/1459
Filed: 1980-07-29
Abstract: PURPOSE:To determine the quality of blood by comparing the emission of a weak light from a test blood with the emission of a light from the normal blood as standard after it is measured. CONSTITUTION:A indicates a light emission of blood for normal persons, B that for diabetes patients, C that for cancer patients and D that for leukemia patients. Points are different by age and sex. The values for narmal persons are below about  40 counts/10sec whereas the emission for B-D distributes almost above the value. Abnormality of the blood, if any, will increase the emission thereby making a  judgement on blood possible. A photomultiplier tube of a measuring device varies with ambient temperatures or the like. In practice, establishing the ratio between a dark count of the device, the count of the blood of normal persons and the count of the blood to be measured provides an effective identification of blood. The average value between 10-100sec is enough for counting which requires about 1-2min for inspection, thereby enabling a quick inspection.
