Abstract: PURPOSE:To relieve the progression of the cleaning and erosion on the surface of a target by forming the plasma having a forming area different, from the forming area of the plasma for treatment at the time exclusive of the film forming treatment time. CONSTITUTION:The target 22 is mounted on a 2nd electrode 17 and a 1st electrode 16 carried in and set with a wafer 15 to be treated into a treating chamber 11 is disposed to face the target 22. After a prescribed atmosphere is maintained in the chamber 11, a voltage is impressed between the electrodes 16 and 17 to form the plasma Pa. This plasma is restrained in the vicinity of the target 22 by exciting inside and outside coils 31, 32 of a double electrode electromagnet device 30. The forming area of the plasma is expanded and contracted by increasing and decreasing the magnetic flux density distribution and/or electric power by the respective coils under the command of a controller 34. The voltage is impressed between a shutter 23 held closed during the period exclusive of the film forming treatment period and the electrode 17 to excite the coils 31, 32, by which the plasma Pb is formed. This plasma is displaced in the same manner as mentioned above to form the plasma for preventing fault expanded more than the plasma forming area at the time of the treatment.

Title: Double conversion type high frequency circuit
Inventor: WATANABE TAKASHI
IPC: H04B1/26
Filed: 1995-09-29
Abstract: PROBLEM TO BE SOLVED: To make an oscillator into an integrated circuit(IC) even without using any crystal oscillator by providing a frequency divider for generating a reference frequency signal for controlling the PLL of a preceding stage converter by dividing the frequency of an oscillated output for generating a frequency suitable for a following stage converter. SOLUTION: An inputted high frequency signal is sent to a mixer 20 and converted to an IF signal based on the output of an oscillator 22. The oscillator 22 receives a signal, for which the frequency from a SAW oscillator 24 is divided by a frequency divider 27, as the reference frequency signal of a PLL control part 21. Then, the output of the IF signal is sent through an amplifier 13, AGC 18, BPF 16 and amplifier 14 to an I/Q analog demodulator 23. This I/Q analog demodulator 23 demodulates signals I and Q based on the frequency signal from the SAW oscillator and sends them to the following stage. In this case, since the oscillator 22 divides the frequency signal from the SAW oscillator 24 while using the frequency divider 27 and receives that signal as the reference frequency signal of the PLL control part 21, the oscillator can be composed of integration enabled parts even without using any crystal oscillator.

Title: Portable loudspeaker device
Inventor: MOMOSE KIYOJI
IPC: H04R3/02
Filed: 1987-11-02
Abstract: PURPOSE:To reduce the size and weight of a portable loudspeaker device and, at the same time to improve using feeling and tone quality of the device, by installing a HPF whose cutoff frequency is higher than the lowest resonance frequency of a direct radiation type loudspeaker and a LPF whose cutoff frequency is lower than highband frequencies to an amplifier. CONSTITUTION:A direct radiation type loudspeaker 2 having a wide output frequency band is used. In addition, by using a LPF 8 of a cutoff frequency fc2 and a HPF 9 of a cutoff frequency of fc1, the amplifying band is limited. When a microphone 1 and loudspeaker 2 are brought nearer to each other, reverberation or howling produced by the feedback of the output of the loudspeaker can be prevented. Since the base plate 3 provided with the microphone 1, loudspeaker 2, and an amplifier 6 and a battery 5 are housed in a case 3 in a united state, relations between the lowest and highest resonance frequencies fo and fh of the loudspeaker 2 and cutoff frequencies fc1 and fc2 of filters can always be maintained at constant states and, even when the characteristic of the loudspeaker varies, a uniform quality can be obtained when adjustment is made on individual filters.
