Title: Rotary photocoupler
Inventor: URATA HARUSHIGE
IPC: H04B10/11
Filed: 1987-04-08
Abstract: PURPOSE:To prevent a rotary photocoupler from improperly contacting or generating a noise due to a sliding contact by composing the photocoupler by rotatably coupling a light emitting unit containing case having a light emitting element to a photodetector containing case having a photodetector. CONSTITUTION:A rotary photocoupler is composed by providing a light emitting unit containing case 11 having a light emitting element 14 for converting an electric input signal to output an optical signal, and a photodetector containing case 12 having a photodetector 17 for converting an optical signal into an electric signal, bringing the optical axes of the element 14 and the photodetector 17 into coincidence, and rotatably coupling the case 11 to the case 12 at the optical axes as a center. Accordingly, the element and the photodetector operate the communication of the electric signal by mechanical means in a conventional rotary unit instead of communicating the optical signal on the basis of the optical coupling. Thus, mechanical sliding contact is eliminated to prevent the photocoupler from improperly contacting or generating a noise.

Title: Semiconductor device
Inventor: FUKUI HIROKI
IPC: H01L21/8249
Filed: 1987-04-07
Abstract: PURPOSE:To improve punch-through withstand voltage between a collector and an emitter without enlarging a film thickness of an epitaxial growth layer, by forming, through the same diffusion process, well regions of a C-MOS transistor element inside a base region directly under an emitter diffusion layer in a vertical type bipolar transistor. CONSTITUTION:After P<+> burial layers 5a, 8, 9a, and N<+> burial layers 12 are formed on a P type semiconductor substrate 1, an N type epitaxial growth film 2 is made to grow. Phosphorus ion implantation processes are performed respectively in a region where a P-ch MOS transistor 20 is formed and in a region where a vertical type PNP transistor 40 is formed, and further N type well regions 4 and 11 are simultaneously formed. Because the formation of the N well region 11 then causes an impurity concentration of the N type epitaxial layer 2 in this region to be increased ten times or so, depletion layer's extension from a collector of the vertical type PNP transistor 40 to its emitter is perfectly stopped in this region, and so a punch-through withstand voltage can be set to 70V or more.

Title: Power supply
Inventor: YAMADA KENJI
IPC: H02M3/28
Filed: 1998-03-31
Abstract: PROBLEM TO BE SOLVED: To provide a power supply which breaks the connection between the second winding of a transformer and a primary controlling circuit by detecting the open state of the diode side of the first winding of the transformer during steady state. SOLUTION: At energy-saving operation, an energy-saving control signal P1 is received from a host system, an output V1 is decreased with a secondary controlling circuit 5, and power is supplied from a second winding N2 of a transformer T1 to a primary control circuit to hold the energy-saving operation. In the near time, when the path at a diode D1 side of a first winding N1 is opened at steady operation, the base path of a third switching element Tr2 is interrupted to stop the operation, which makes a fourth switching element Tr3 operate. By making the fourth switching element operate, a second switching element Tr1 is stopped, and the supply of power from the second winding N2 of the transformer T1 is shut off, so that the second switching element Tr1 and the energy-saving circuit are fully protected.

Title: Communication right control system
Inventor: IKUSHIMA MIE
IPC: H04L12/40
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To shorten the communication interval of communication in a one-to- multiple communication system and to more smoothly utilize equipment by providing slave equipment with a peculiar connection number and applying the right of communication in the ascending order to the maximum communication number connected to master equipment. SOLUTION: After the power source of master side equipment is turned on, the communication right is applied in the ascending order to the connection number of connected equipment. When the maximum connection number is achieved, the presence/absence of equipment having the next connection number is confirmed. When there is connected equipment, communication is performed, and further the presence/absence of connected equipment having the next connection number is confirmed. When there is no connected equipment, the communication number is applied to the minimum connection number and the communication right is applied in the ascending order to the maximum connection number. Since the probability of applying the connection right to the non-connected number is lowered, time for reflecting the equipment of observation with the contents of communication from the connected equipment can be shortened and equipment can be more smoothly utilized.

Title: Beverage extactor for automatic vending machine
Inventor: KAWABATA AKIO
IPC: G07F13/06
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To provide a beverage extractor for an automatic vending machine capable of circulation control without using a valve mechanism and preventing deficiency such as a hot water leakage and the loss of extraction pressure. SOLUTION: In this beverage extractor for an automatic vending machine which presses pneumatically hot water B thrown into a hot water cylinder 2 with a vertically moving hot water piston 221 to sweep it to an extraction cylinder and extracts a beverage from raw material in the extraction cylinder, a hot water path 223 whose entrance faces the bottom part of the cylinder 2 and which leads the water B of the cylinder 2 toward the extraction cylinder is formed and also, the halfway of the path 223 is formed higher than the hot water level of the cylinder 2. When the hot water is thrown into the cylinder 2 in this way, the hot water in the cylinder 2 is prevented from flowing toward the extraction cylinder.  Subsequently, when pressure is applied to the cylinder 2 internally with the piston 221, this air pressure makes the hot water in the cylinder 2 flow over the highest position of the path 223 to be swept away toward the extraction cylinder.

Abstract: PURPOSE:To attain exposure control with high accuracy and simple constitution by using a charge transfer stop means to stop a vertical transfer function of a vertical charge transfer means when a light is made incident on an image pickup element and transferring the stored charge to an exposure part for a prescribed time by a shutter. CONSTITUTION:When a release 18 is depressed, a control circuit 17 drives a floppy 9 via circuits 12, 11, and drives a stepping motor 4 via a circuit 5 to drive an aperture blade 2, outputs a stop signal (d) to a CCD drive circuit 6 thereby stopping a clock to drive register of a CCD 3. When the blade 2 is stopped to a prescribed position, the circuit 6 outputs a shutter pulse (e) to stop the circuit 6. The CCD 3 starts storing the signal charge. When the pulse (e) descends, the charge stored by the pulse from the circuit 6 is transferred to a vertical transfer register of the CCD 3. The circuit 17 drives the motor 4 to shut the incident light to the CCD 3 by the blade 2. Then the circuit 17 brings the signal (d) to an L level and the signal charge of the CCD 3 is transferred vertically at the circuit 6 and outputted.

Title: Superheterodyne receiver
Inventor: KOGA HIROSHI
IPC: H04B1/26
Filed: 1982-05-25
Abstract: PURPOSE:To improve the distortion due to the phase nonlinearity of a filter remarkably, by preventing a side band component from passing through an intermediate frequency filter. CONSTITUTION:An output F1 of a front end 1 and an output F3 of the 3rd multiplier 5 are inputted to the lst multiplier 2. Let F1 and F2 be F1=f1+ or -DELTAf1 and F3=f3+ or -DELTAf3 in this case, then a signal passing through the 2nd intermediate frequency filter 3 is F1F=F1-F3=(f1-f3)+ or -(DELTAf1-DELTAf3), and the side band wave is compressed into DELTAf1-DELTAf3. Then, an output F2 of the 2nd multiplier 4 is F2= FIF+F3=f1+ or -DELTAf1=F1 and the compressed side band wave is restored. On the other hand, the output F3 of the 3rd multiplier 5 is F3=F2-f0 (where f0 is local oscillating frequency=f1-f3)=f3+ or -DELTAf1. Thus, since DELTAf1=DELTAf3 and FIF=f1-f3 are obtained, the side band wave is suppressed completely. The 2nd intermediate frequency only not having the side band component passes through the filter and the passing lower side band component is restored.
