Title: Method and device for plasma treatment
Inventor: KAWAI YOSHINOBU
IPC: H01L21/31
Filed: 1998-05-13
Abstract: PROBLEM TO BE SOLVED: To perform treatment, such as film forming and etching on a wafer using ECR(electron cyclotron resonance) plasma with a high in-plane uniformity. SOLUTION: Density of electrons at an ECR point, separated from and opposite a substrate to be treated, is set to equal to ore mor than 0.46 nc and less than one nc which is a cut-off density on the side of the upper limit of X-wave. In this way, an electron density distribution is formed with large crests at both ends of the region and with peak values in the center of the region which are lower than those at the ends. In this case, the outer perimeter of the magnetic field between the ECR point and the substrate cuts once the inner walls of the vacuum chamber and a space of 1/4 or more of the wavelength of the X-wave is formed between the outer perimeter and the inner walls towards downstream.

Title: Sample and hold circuit
Inventor: KAGA MASAKAZU
IPC: H03M1/12
Filed: 1991-06-20
Abstract: PURPOSE:To make smaller an amplitude signal depending on an amplitude of an input signal without deteriorating high speed characteristic by dividing the input signal voltage with a capacitor and enables selection of amplification factor depending on capacity and the number of capacitors. CONSTITUTION:When a control switch 106 is ON, a charge voltage becomes equal to an input signal voltage and even if the switch 106 turns OFF, the charge voltage is held. In this case, when voltage dividing switches 107, 108 are respectively in the ON and OFF states, the capacitors 104, 105 are charged up to the total capacity thereof. Moreover, if the switches 107, 108 are respectively in the OFF and ON states, a voltage is divided with a capacitance ratio of the capacitors 104, 105 and these voltages are input to an operational amplifier 101. Therefore, when a higher amplitude signal is input, switching operation of the switches 107, 108 is carried out to divide the input signal voltage and thereby a proper amplitude signal can be input to the amplifier 101. In this case, since voltage dividing is carried out by a capacitor, a time constant of circuit input does not increase and highs peed operation can be realized.

SOLUTION: A cargo compartment 20 is provided with a partition 30, which can be opened and closed, for partitioning the compartment 20 into a front compartment (one end space) 21 having a refrigerating device 50 and a rear compartment (the other end space) 22 without having the refrigerating device 50. When the partition 30 is kept closed, only the front compartment 21 is refrigerated by the refrigerating device 50. At this moment, the rear compartment 22 has the normal temperature since it is partitioned by the partition 30. When the partition 30 is closed, it is held by an opening frame 23, and therefore the cargo compartment can be divided into two spaces. Accordingly, only with the opening and closing operations of the partition, the volume of the refrigeration space in the cargo compartment can be changed in two steps.
