Title: Controller for rotational frequency of record player
Inventor: OBATA SHIYUUICHI
IPC: G11B19/28
Filed: 1983-07-13
Abstract: PURPOSE:To control continuously and high accurately the rotational frequency of a record player, by controlling the rotational frequency on the basis of the sum of frequencies of two oscillators, and varying continuously the frequency of one of the two oscillators. CONSTITUTION:A turntable driver is provided with a driving circuit 1, frequency generator 3, frequency-voltage converter 4 and a phase comparator 6. The rotational frequency of the turntable is controlled to obtain the same frequency and same phase between a signal fG and the output signal fs of a frequency divider 29. The rotational frequency is varied in proportion to the frequency fs. While a frequency controller is provided with oscillators 21 and 25, frequency dividers 22 and 24, a frequency subtractor 23, phase comparator 26, LPF27 and a voltage controlled oscillator 28. An output signal fR=fM-fN is obtained from the subtractor 23. The oscillator 28 produces a frequency signal f0 in proportion to the output voltage of the comparator 26 which is proportional to the phase difference between signals fR and fV. The dividing ratios of dividers 22 and 24 are selected properly together with the frequencies of oscillators 21 and 25. As a result, the signal f0 can be varied continuously on the basis of a signal fI by changing the signal fV.

Title: Gaseous carbon dioxide detector
Inventor: NISHIGUCHI MASASHI
IPC: G01N27/406
Filed: 1990-05-17
Abstract: PURPOSE:To maintain high reliability by providing an electric power supplying means for supplying an electric power to a heating part with an atmosphere temp. detecting means which detects a measuring atmosphere temp. and a heating control means which controls the temp. of the heating part according to the atmosphere temp. CONSTITUTION:The resistance value of a temp. measuring element 13 changes according to the temp. change of the atmosphere. The output voltage of the atmosphere temp. detecting means 11 obtd. from the mid-point of the element 13 and a resistor 14 increases on lowering of the temp. and decreases on rising of the temp. The heating control means 12 converts the output of the means 11 and supplies a heating current to the heating part 3 by a power transistor 19. Consequently, the output of the means 11 increases when the temp. of the heating part 3 falls on lowering of the atmosphere temp. The supply voltage from the means 12 to the heating part 3 is then increased and the temp. of the heating part 3 is elevated. The temp. of the gas sensing part 2 heated by the heating part 3 is kept constant regardless of the change in the atmosphere temp. by adequately setting the temp. constant of the element 13 and the conversion constant of the means 12. The dependency of the sensor output on the temp. is thus compensated.

Title: Method and apparatus for manufacture of semiconductor device
Inventor: IWAMA RYUJI
IPC: H01L21/285
Filed: 1989-05-23
Abstract: PURPOSE:To manufacture wirings having satisfactory coverage and flatness by a method wherein, after the wirings made of Al or alloy mainly composed of Al are formed on a substrate by a sputtering method, the substrate to be treated is heated to the temperature higher than 2/3 of the melting point of the wiring material in terms of an absolute temperature without being released in the air. CONSTITUTION:Wiring layers made of Al or alloy mainly composed of Al are formed on a semiconductor substrate having step parts by a sputtering method. Then the substrate to be treated is subjected to a process in which the substrate is heated to the temperature higher than 2/3 of the melting point of the material of the formed wirings in terms of an absolute temperature. That is, under a temperature higher than 2/3 of the melting point of the alloy, metal atoms have sufficient energy to move and the mobility is increased. If these properties are utilized, Al on the step parts is sufficiently fluidized to improve the step coverage by the action of a surface tension. Moreover, if the temperature is elevated close to the melting point of the used metal, the step coverage can be improved significantly.
