Title: Discrimination of young liquor and urn aged one of millet brandy (awamori)
Inventor: TAMAKI TAKESHI
IPC: G01N33/14
Filed: 1983-07-12
Abstract: PURPOSE:To accurately perform the discrimination of young liquor and urn aged one of millet brandy (AWAMORI), by utilizing such a fact that the metal component of urn aged liquor is more than that of young one, on the basis of one or more component in the specific metal component group in millet brandy. CONSTITUTION:The accurate discrimination of urn aged liquor and young one of millet brandy (AWAMORI) is enabled through measurement due to an atomic absorption spectroscopic method by utilizing such a fact that metal components such as iron, copper, Ca, Mn, K or Na eluted from the urn are contained in urn aged liquor and the content thereof is diferent from that of young one. For example, a definite amount of millet brandy is evaporated to dryness and 0.5 N-HCl aqueous solution is added to the dried one and, according to circumstances, the resulting mixtue is diluted to prepare a specimen solution which is, in turn, used to measure the content of one more of aforementioned metals by an atomic absorption spectrophotometer. The measured result is compared with a calibration curve obtained by performing similar measurement by using a reference solution of a respective metal to know the metal content in millet brandy.

Title: Tape recorder
Inventor: KAWASE OSAMU
IPC: C07D261/20
Filed: 1981-08-10
Abstract: PURPOSE:To eliminate unstable operating state of a tape run mechanism, by providing a changeover switch for a control circuit so that a predetermined tape run mechanism only gives a prescribed operating state at all times. CONSTITUTION:For example, a capacitor 30 is inserted to a switching circuit 27 of a circuit system 1 to provide a time delay for the transit operation from ON to OFF of the switching circuit 27 and the 2nd circuit system 2 is transferred to non-operating state before the 1st circuit system 1. Thus, when the two tape run mechanisms are simultaneously operated, if a changeover switch 34 is selected to the fixed contact (b), the 1st tape run mechanism only keeps the operating state without fail. Then, such an unstable state under which it is not clear which mechanism remains out of the two tape run mechanism, can be eliminated.

Title: Compressor
Inventor: NISHIZAWA KAZUTOSHI
IPC: F04C28/10
Filed: 1983-07-11
Abstract: PURPOSE:To reduce the starting-up torque by forming a pressure chamber in an intake piping and forming a communication passage which communicates to said pressure chamber and the inside of the intake piping and installing a member which increases and reduces the flow area of the intake piping by the differential pressure generated between the pressure chamber and the inside of the intake piping. CONSTITUTION:When a compressor is started or the number of revolution increases sharply, a large driving torque is made necessary, and the pressure in an intake piping 30 reduces sharply. Then, a plunger 33 which is usually accommodated perfectly into a pressure chamber 32 is projected onto a passage 15 side by the differential pressure between the pressure chamber 32 and the passage 15a, overwhelming the urging force of a spring 34, and the passage 15 is throttled. When the differentail pressure generated between the pressure chamber 32 and the passage 15a increase further, the plunger 33 projects further to close the passage 15a. Thus, by throttling the passage 15a on starting or on sharp increase of the number of revolution, the flow rate of the coolant introduced into the compressor reduces, and the intake pressure reduces sharply, and the driving torque is reduced.

IPC: F02D41/12
Filed: 1983-07-12
Abstract: PURPOSE:To smoothly decrease an engine rotational speed, by increasing an amount of air bypassing a throttle valve when the engine rotational speed is not more than a predetermined value and an amount of decrease in the rotational speed is not less than a predetermined value. CONSTITUTION:A target rotational speed NF according to an operational condition and an estimated duty ratio De according to an estimated amount of air are set. When an ISC timing is reached, an average value NE of an engine rotational speed is calculated, and a basic duty ratio Do for feedback controlling the average value NE to the target rotational speed NF is calculated.
