Title: Full automatic device of wiper
Inventor: SHIMIZU SUMIO
IPC: H02P3/08
Filed: 1981-12-30
Abstract: PURPOSE:To fully automatically operate a wiper, by both driving the wiper when a rain fall sensor detects a rain drop and stopping to drive the wiper when an output of a frictional force sensor, which detects frictional force between a wiped surface and wiper blade, exceeds a prescribed value. CONSTITUTION:At running of a vehicle when it begins to rain, and a rain fall  sensor 2 operates, an output of a waveform shaper circuit 17 becomes a level L  to operate a differentiating circuit 18 and generate a negative pulse signal. This signal causes an output end 19c of RS-FF19 to be a level H, and a transistor T1 is turned on to close a contact S1 by operation of an exciting coil RE1. In this way, a wiper motor M is driven intermittently by an intermittent amplifier 20 or the like. Thereafter, when the rain stops, frictional force between a wiped surface and wiper blade is increased larger, an output of a comparator 16, to which  an output of a frictional force sensor 2 is input after passing through an amplifier 13, rectifier 14 and integrator 15, becomes a level L, then an output of FF19 is inverted to turn off the transistor T1 and stop a wiper.

Title: On-line constitution control system
Inventor: TAKEUCHI YASUSHI
IPC: G06F15/00
Filed: 1985-09-27
Abstract: PURPOSE:To reduce a case reaching a long time fault by using a system constitu tion table with a correct content to apply re-IPL even when a fault takes place in an exchange while the system constitution table is being rewritten. CONSTITUTION:In the case of IPL, an exchange 3 has a flag representing that a program is loaded from a side A or B in a disc device 8 and the flag is rewritten by the command of a NCS 1. The flag is set to the side A in the normal on-line, the NCS 1 distributes a table to the exchange 3 and when it is finished, the flag is rewritten on the side B. Then the exchange 3 copies the content of the side B onto the side A. The exchange 3 restoring the flag to the side A again by the instruction from the NCS 1 uses the IPL to load a program and a new table and the on-line service is started. If a fault takes place in the exchange 3 during the distribution of table from the NCS 1 to the exchange 3, the IPL is aplied from the side A according to the flag to restart the service immediately by the system constitution before change.

Title: Multiplying circuit
Inventor: SEGAMI KOICHI
IPC: H03D1/18
Filed: 1989-08-18
Abstract: PURPOSE:To efficiently obtain a square-law output even if a difference is generated in a DC bias of positive phase and negative phase inputs by providing two differential amplifying circuits in which current values of a constant-current source are the same on an input stage of a multiplying circuit and inputting the respective load resistance outputs to the multiplying circuit through an emitter follower. CONSTITUTION:DC components of collector currents I9, I10 of transistors (TR) 47, 48 become constant irrespective of a base DC bias of the TRs 47, 48, since its constant-current source 55 is common. Accordingly, a current bias generated in a load resistance 57 becomes constant. Also, as for a signal voltage, since a signal current flows through a capacitor 59, the gain of the TR 47 is proportional to RL1/Re1, and a linear operation range becomes Re1.I01. Therefore, in the case of Re1 > Re2, when a value of V3 is adjusted appropriately so as to become V1 > V3, the TRs 47, 50 can hold a linear range. In such a way, even if a difference is generated in a DC bias of positive phase and negative phase inputs, a square-law output is efficiently obtained.

Abstract: PROBLEM TO BE SOLVED: To accurately detect toner concentration without using a toner sensor and an A/D converter and to control the concentration by grasping the state of image data, calculating toner consumption and always keeping the fixed toner concentration based on the calculated consumption. SOLUTION: When one line of image data is inputted from an enumeration data transmission part 130, a CPU 160 calculates the toner consumption coefficient of the line. Next, a weighted value corresponding to the toner consumption coefficient is searched, and the weighted value with respect to the present image data of the input line is set. By dividing an accumulated weighted value obtained by accumulating and adding up the weighted values of the respective lines equivalent to one page by the number of whole lines constituting one page, a page average weighted value is calculated. Then, a toner supply time for supplying toner consumption corresponding to the average weighted value, that is, a toner motor driving time is obtained. A toner supply motor driving part 180 is controlled according to the set toner supply motor driving time.

Abstract: PROBLEM TO BE SOLVED: To easily arrange an in-channel reinforcement, ensure a proper positioning work for securing the quality of a construction work using a slab, and extend a beam span for allowing the use of a deck plate. SOLUTION: Both ends of a deck plate 11 are formed to have deck beam placement parts 12, with the deck plate 11 crushed over an area from the lower side thereof to the mid-height position, and the beam placement parts 12 are placed on a beam 2.

In this case, the need of a spacer dedicated to the arrangement of the in- channel reinforcement 5 is eliminated, or only a small number of spacers is required, even if necessary. Also, the height (h) of the deck plate 11 can be enlarged and rigidity is increased, without increasing height h' from the upper surface of the beam 2 to the upper surface of the deck plate 11. As a result, a usable beam span can be extended without increasing the floor height of a building.
