Title: Electronic circuit
Inventor: UYA MASARU
IPC: H03K19/017
Filed: 1981-04-06
Abstract: PURPOSE:To reduce the delay of signal propagation by charging or discharging a signal line only when the voltage of the signal line is within a prescribed range. CONSTITUTION:For the transmission of a binary voltage which has a 0 V low level and a VDD high level, VL is set for the low level side, and VH for the high level side. (0<VL<VH<VDD.) A detecting circuit 2 outputs a ''0'' when the voltage of a signal line is lower that the VH, or a ''1'' when between the VH and VDD. A detecting circuit 3 outputs a ''0'' when the voltage of the signal line is lower than the VL, or a ''1'' when between the VL and VDD. When the voltage of the signal line 1 is varying from the 0 to the 1, a transistor 7 turns on while the output of the detecting circuit 2 rises up to the ''1'' after the output of the detecting circuit 3 goes up the ''1'', thereby raising the voltage of the signal line rapidly.

Title: Automatic welding robot
Inventor: IHARA YASUSHI
IPC: B23K9/12
Filed: 1979-04-26
Abstract: PURPOSE: To make the torch turning angle controlling of the captioned robot simple and easy by making welding mounting fitting turnable, positioning the torch welding point on the fitting rotating axis and retreating and turning the fitting by the output of the hindrance detecting center of the fitting turning side.  
     CONSTITUTION: The body 1 is attracted to the surface of the work W by energizing of a magnet chuck 2 and an arm 4 is bound to the body 1 and a guide bar 7 to the arm 4 by the action of clutch brakes 6, 9. When a switch S 2  contacts the work constituting members while the automatic welding is being executed by the operation of a control unit 3, a power 14 is connected to a minus electric power source to let the torch T turn clockwise. The torch T is controlled of its turning angle ϕ while the operation and nonoperation of the switch S 2  are being repeated until the welding point WP of the torch T reaches the welding and point WL 2  and therefore the breaking of the torch by colliding against the work W does not occur. The welding point WP of the torch T is on the turning axis V-line irrespective of its turning angle ϕ and therefore there is no hindrance in the execution of the welding.

Title: Production of monomolecular film and production of monomolecular piled up film
Inventor: SANO KENJI
IPC: C09K11/00
Filed: 1992-03-11
Abstract: PURPOSE:To increase the bonding strength of molecules to a substrate and to obtain the monomolecular film oriented with the molecules oriented in the same direction by treating the surface of the substrate to impart reactivity thereto and bringing functional groups into reaction with the surface of the substrate by using the specific molecules. CONSTITUTION:The surface of the substrate 1 is treated, by that, the reactivity is imparted to a treated layer 2. The molecules 3 having the two functional groups at both ends of the rigid molecular skeleton having >=15 angstrom length are used and one of the two functional groups is brought into reaction with the surface of the substrate 1, by that, the monomolecular film of the first layer is formed. Further, the molecules 4 having the two functional groups at both ends of the rigid molecular skeleton having >=15 angstrom length are used and one of the two functional groups is brought into reaction with the other functional group of the molecules constituting the monomolecular film of the lower layer, by that, the monomolecular film of the upper layer is formed. The reason that the length in the longitudinal direction of the molecular skeleton is limited to >=15 angstrom lies in that the control of the molecule orientation on the substrate 1 is difficult if the length is below 15 angstrom.

Title: Reception data processing system for tele-control coupling device
Inventor: TOMITA MATSUO
IPC: H04Q9/00
Filed: 1996-03-11
Abstract: PROBLEM TO BE SOLVED: To prevent the reception buffer of a tele-control coupling device from being fully occupied even when reception busy is consecutive in a host device. SOLUTION: A call is sent to a host device (S21), the end of transmission is discriminated (S22), in the case of a busy state whether or not the busy state is consecutive is discriminated (S23). When yes, data are aborted (S28). Reception data of a succeeding reception buffer are sent by the input of a return key. When no, retrial processing is conducted (S24-26). In the case of in excess of retrial umber of times set in this processing, discrimination of a consecutive busy state is set (S23). When the discrimination of the transmission end indicates a busy state (S22), data are aborted without the retrial processing (S28) and next transmission is conducted. When resident data are recovered, the discrimination of transmission end is set OK (S22), a busy consecutive state discrimination means (S23) is reset (S29). Thus, succeeding retrial processing (S24-26) is attained.

Title: Parity information transferring device
Inventor: WATANABE HARUKI
IPC: H04L1/00
Filed: 1988-03-07
Abstract: PURPOSE:To prevent a control signal from being made discontinuous even after a branching in a branching device by converting a specific parity bit made into the control signal by means of the even/odd parity information of the parity bits extracted from the signal. CONSTITUTION:An even/odd detecting part 1 detects the even/odd of the number of bits except for the parity bit of the signal from one terminal station, and a parity bit detecting part 2 detects the even/odd of the parity bits of the signal from one terminal station. A non-coincidence detecting part 3 detects a non- coincidence between the even/odd of the parity bits estimated from the detection result of the even/odd detecting part 1 and the even/odd of the parity bits detected by the parity detecting part 2, and a parity control part 4 inverts the parity bit in data to be multiplexed by the branching device and to be transmitted to the opposed terminal station at the time of detecting the non- coincidence in the non-coincidence detecting part 3. Consequently, when a violation is executed, the parity bit is inverted and outputted. Thus, in the signal to be transmitted, the control signal to utilize the parity bit is correctly stored, and it cannot be made discontinuous.

A toner 30 is attracted on the surface of the sleeve 26 by the magnet 24, and is thinned to the prescribed thickness of a layer by a magnetic blade 32. In terms of clearance l between the sleeve 26 and the blade 32 with respect to the photosensitive body, the clearance of the developing unit at the downstream side is larger than that at the upstream side. Accordingly, when the clearance l is set larger, an appropriate density can be obtained even if the contrast potential of the photosensitive body is small, and its dark attenuation can be compensated with a far simple constitution.
