Title: Temperature detection circuit
Inventor: MIYAMA HIROYUKI
IPC: G01K7/24
Filed: 1988-11-29
Abstract: PURPOSE:To detect the change of temperature as the change of frequency by control ling the oscillation frequency of a ring oscillator with a resistance having a tempera ture coefficient. CONSTITUTION:The voltage of both ends of a capacitor(C) 111, that means, the input voltage of an inverter 102 is change with delay by a time necessary for the C 111's charging and discharging as compared with the change of the voltage of the input terminal of an inverter 101. The same is true for inverters 102-105. The oscillation frequency of the ring oscillation circuit consisting of the inverters 101-105 and the Cs 111-115 is decided with the delay of the change of the voltage. Supposing that the capacity of the C is constant, the charging and discharging time is decided based on a charging and discharging current. Since the charging and discharging current is applied between the drains and the sources of metal oxide semiconductor type electric field effect transistors 121-125 and 131-135, the current is decided based on the resistance value of the resistance 140. Therefore, the charging and discharging time of the Cs 11-115 is decided based on the resistance value of the resistance 140. Since the resistance value of the resistance 140 is provided with the temperature coeffi cient, the oscillation frequency of a temperature detection circuit 100 is changed in accordance with the temperature.

Title: Acoustic diagnosis method for rotary machine
Inventor: GOMITA HISAMITSU
IPC: G01H17/00
Filed: 1989-11-22
Abstract: PURPOSE:To make it possible to diagnose the defective sound of a rotary machine by using an acoustic signal at the spot where background noises are large by using a frequency which is different from a commercial power source as the frequency of the power source for driving the rotary machine. CONSTITUTION:The frequency of a power source 2 is set at about a half of the frequency of, e.g. a commercial power source. A current is supplied to a rotary machine 1 through a switch circuit 3. The large current flows through the rotary machine 1, and the magnetic flux in the rotary machine is saturated. Therefore, the rotor and the stator of the rotary machine 1 are vibrated with strong exciting force. The large vibrations and sounds are generated with the natural frequencies of the rotor and the stator. Then, the sound is detected with a sound detector 4 and transduced into an electric signal. Then, the electric signal passes through a filter 5 which is preset for the frequencies of the natural frequencies of the rotor and the stator. Only the characteristic sound component is taken out. Then, the sound signal passed through the filter 5 is converted into a DC level through a square detection averaging circuit 6. The signal undergoes A/D conversion in an A/D converter 7, and the result is stored as the acoustic data.

IPC: H04N1/41
Filed: 1988-12-01
Abstract: PURPOSE:To efficiently encode a picture signal by transforming the N components of a picture into uncorrelated components.

Title: Correcting method for phase shift mask
Inventor: JINBO HIDEYUKI
IPC: G03F1/72
Filed: 1992-11-12
Abstract: PURPOSE:To provide a correcting method for a phase shift mask which does not substantially affect a resist pattern even if any defective part exsists in the mask. CONSTITUTION:When the defective part is corrected, the light transmittance in the corrected region is reduced and the light intensity of the transmitted light beam passed through the region is thus reduced. Consequently, when the mask pattern of the phase shift mask is projected on a wafer by using a reduction stepper the distribution of the light intensity at an image-formed position of the projection optical system is smaller than the light intensity corresponding to a region not corrected because the light intensity (at the normal time) at a position corresponding to the corrected region has the defective part. In this case, auxiliary openings 19 and 22 are formed at the defective parts 16 and 20, i.e., at a light shielding pattern 14 in close vicinity to the corrected region. The transmitted light beam passed through the auxiliary openings 19 and 22 compensates for the reduction of the light quantity of the transmitted light beam at the corrected region, thereby raising the light intensity at the corresponding image-formed position toward a light intensity level at the positive normal time. Thus, the formation of a prescribed resist pattern as previously designed is allowable.
