IPC: H04M1/67
Filed: 1990-09-20
Abstract: PURPOSE:To improve the convenience by providing a function operating a slave set to be an incoming call exclusive set and a timer function setting a time to operate the slave set as the incoming call exclusive set to a master set. CONSTITUTION:A master set has a function of operating a slave set as an incoming call exclusive set and has a timer function to set a time when the slave set is acted as an incoming call exclusive set and also a timer 15 to set the incoming call exclusive time of the slave set. When a slave set operating mode setting button 61 is depressed, the signal is sent to a CPU 1 from an operation section 8 and the CPU 1 sets a prescribed time to the timer 15 and gives an instruction of lighting of a slave set operating mode LED 17 to a display section 7. Thus, the incoming call exclusive time of the slave set is set and an undesired external line call is prevented from the slave set for the period and the release of the incoming call exclusive setting is implemented without visiting the master set and the handling trouble is saved.

IPC: C30B15/00
Filed: 1999-09-06
Abstract: PROBLEM TO BE SOLVED: To provide a silicon wafer capable of being used in place of a p/p+ epitaxial wafer and a method of producing the same. SOLUTION: The objective wafer is a silicon wafer doped with boron and nitrogen. The concentration of boron in a surface layer part to a depth of at least 0.2 μm from the surface is <=1/2 that of boron in a bulk part of the silicon wafer, and the density of the defects having sizes of >=0.09 μm is <=1.0×104 defects/cm3 in the surface layer part. Further, after subjecting the silicon wafer to oxygen deposit heat treatment, the density of internal fine defects in the bulk part is in the range of 1.0×108 to 2.0×1010 defects/cm3.  The method for producing the silicon wafer comprises growing a silicon single crystal rod doped with boron and nitrogen by a Czochralski method, then slicing the grown single crystal rod to obtain the silicon wafer and heat treating the silicon wafer under an atmosphere containing hydrogen to allow boron present on the surface layer of the wafer to diffuse toward outside.

Title: Voltage converter
Inventor: KURION PETEI
IPC: H03K19/00
Filed: 1990-09-20
Abstract: PURPOSE: To convert an ECL input signal into a TTL or a CMOS compatible level without introducing current spike into output signals by preventing the simultaneous conducting in a 1st and a 2nd switching means at the prescribed slew rates of a 1st and a 2nd drive signals. CONSTITUTION: The 1st and the 2nd switching circuit 81 and 110 supply output signals having the 2nd prescribed logic level responding to the 1st and the 2nd converted differentially relevant signals having the 1st and the 2nd single- terminated levels, respectively.

Inventor: TSUKADA KAZUE
IPC: E03B11/00
Filed: 1995-09-04
Abstract: PROBLEM TO BE SOLVED: To facilitate installation, and to mount this device regardless of a height place to a drainage canal at the place of installation by laying a water- permeable material before the outer wall of a water storage tank in the peripheries of at least outlets and burying the water storage tank in the ground in the water storage tank, in which a large number of outlets are disposed crosswise to the side wall surface of an upper section and which consists of a noncorrosive material.

Title: Method and apparatus for mixing or dispersing particles
Inventor: KIMURA ISAO
IPC: B01F13/00
Filed: 1987-10-08
Abstract: PURPOSE:To mix or disperse particles perfectly by allowing a container made of a dielectric substance to pass through an active region of an electric field curtain so as to electrify the particles contained in that container. CONSTITUTION:An electric field curtain is formed within an electrode assembly 1 by applying a single phase AC high voltage to every electrode 2 of the electrode assembly 1 from a power supply equipment 5. Particles p to be mixed or dispersed, e.g., several species of powder or particles in an aggregated state, are put in a container 8 made of a dielectric substance such as glass, and allowed to drop into the electrode assembly 1 from a carrying-in conveyer 6. While the container 8 is passing through an active region of the electric field curtain, each particle in the container 8 is electrified in contact with the container 8 and subject to a disturbing action caused by the electric field curtain. A perfect mixing or dispersion of the particles is attained until the container 8 arrives at a carrying-out conveyer 7 by using this apparatus.

IPC: H02P1/16
Filed: 1987-10-08
Abstract: PURPOSE:To reduce starting surge current by interrupting power source when current reaches to a first level and resuming power supply when current drops from the first level to a second level. CONSTITUTION:When transistors 100-103 are turned ON, current is fed to a compressor 122.

Filed: 1988-10-07
Abstract: PURPOSE:To take an excellent picture in daylight synchronized flash photography without overexposure by the correcting the measured light brightness of an AE sensor which take an averaged light measurement to a proper value in synchronized flash photography. CONSTITUTION:The AE sensor 38 takes an averaged light measurement of the brightness of a subject, photodetects light separated by a beam splitter 14, and outputs a signal corresponding to the quantity of photodetection to a CPU 30 through a logarithmic amplifier 40. Then when the measured brightness is large and the sensor ratio is large in the synchronized flash photography, the daylight synchronized photography is judged and the measured light brightness is corrected with a brightness correction value to prevent overexposure. Further, when the measured light brightness BV(AV) is small and the sensor ratio K is large, the measured light brightness is corrected with the brightness correcting value having the opposite polarity to eliminate overexposure. Consequently, the exposure dependency of a main subject upon the light of a stroboscopic device 50 is made large to take the excellent picture whose image plane is entirely proper.

Filed: 1992-09-22
Abstract: PURPOSE:To enable expansion of a recording capacity of other digital signal to be multiplexed with a sound signal by recording/reproducing a PCM signal obtained by the same signal processing as a mode III at the same speed as a mode I. CONSTITUTION:PCM sound signal of a sampling frequency of 32kHz compressed nonlinearly by a 1st compression circuit (16 to 12 bits) 11 is converted by a 1st conversion circuit (12 to 8 bits) 12. On the other hand, an 8-bit digital signal is converted into the signal processing cycle of 48kHz to become two symbols per cycle by a digital signal fetching circuit (8-bit video signal) 13. Then, the 8-bit PCM signal and the other 8-bit digital signal are multiplexed by a signal synthesizing circuit (sound/video signal) 14 to generate a 16-bit synthesized signal. This signal is processed by an interleave processing circuit 15, and is recorded/reproduced at the same speed as the mode I, and is converted into 12 bits by a 2nd conversion circuit (8 to 12 bits) 19 via a deinterleave processing circuit 17 and a signal separation circuit (sound signal/video signal) 18. Thus, the recording capacity of the video signal is increased, and the dynamic range of the sound signal is prevented from deteriorating.

Title: Speed control unit of toilet bowl
Inventor: ORII MAKOTO
IPC: A47K13/10
Filed: 1988-10-07
Abstract: PURPOSE:To obtain speed control action stable even with respect to the variation in the mass of an opening/closing body without generating the leakage of oil by providing a brake means applying braking to the rotation of an input shaft rotating a rotary body by applying braking to the rotary body when said rotary body is rotated. CONSTITUTION:When the first opening/closing body 3 is revolved in the first direction, the first input shaft is rotated and a follower rotary body is rotated through the first unidirectional transmitting clutch. A brake means acts on the rotating follower rotary body to apply braking to the rotation to the rotary body. The braking applied to the follower rotary body acts on the first input shaft, that is, the first opening/closing body 3 as braking force to control the revolving speed of the opening/closing body. When the first opening/closing body is rotated in the second direction, the rotation at this time is not transmitted to the brake means by the action of the first unidirectional clutch provided between the input shaft and the follower rotary body and, therefore, the opening/ closing body is rotated in the same direction without receiving braking action. Even in the cases rotating the second opening/closing body and simultaneously rotating the first and second opening/closing bodies, the same action is applied.
