Title: Medium reader
Inventor: KONISHI YOSHIHARU
IPC: G06K7/10
Filed: 1996-10-01
Abstract: PROBLEM TO BE SOLVED: To read an image of a foreign matter to read an image of an object even in the case that the color of the object to a reader and that of the foreign matter are close. SOLUTION: It is noticed that the foreign matter has a rough surface and reflects light in many directions and reflects light in more directions in the case of diffused light irradiation, and a diffusing plate 4 is arranged in front of a light source 3 to make the surface reflection factor different between characters or a pattern and the foreign matter on them. Thus, a difference between the output level of characters or the pattern and that of the foreign matter is generated at the time of read by a photoelectric transducer 1. As the result, the input to the photoelectric transducer 1 is increased to give a difference between output levels for binarization even if the surface of the foreign matter is not uniform, and the object and the foreign matter are distinctly discriminated.

Title: Temperature controller for fixing device
Inventor: AIKAWA YUKIHIRO
IPC: G03G15/20
Filed: 1993-10-19
Abstract: PURPOSE:To prevent the occurrence of a high temp. offset and a fixing fault even when the heat capacity of a thermal roller is small, the fluctuation in a temp. is easy to be affected due to the heat taken by sheets of paper by setting a control temp. higher only when passing a paper. CONSTITUTION:Under the condition that it is the time when passing a paper (that the sheets of paper exist in a fixing device), a certain paper passing through time correction amount D2 is added to the control temp. Tc. When the heat capacity of the thermal roller is set smaller, the heat of a pressure roller is taken by the sheets of paper, the probability that the fixing faults occur in the rear end parts of the sheets of paper exists. In such a case, when the control temp. Tc is set higher only when passing a paper, the occurrence of the high temp. offsets in the top end parts of the sheets of paper and the occurrence of the fixing faults in the rear end parts of the sheets of paper are prevented. That is, when the top end parts of the sheets of paper pass, since the control temp. Tc are set lower until passing, the temp. of the thermal roller become lower, and the occurrence of the high temp. offsets are prevented. On the other hand, when the rear end parts of the sheets of paper pass, since the temp. of the thermal roller become higher, the occurrence of the fixing faults are prevented.

Title: Message receiver
Inventor: ANDO TAKASHI
IPC: G06F15/16
Filed: 1985-11-22
Abstract: PURPOSE:To attain a rapid message response processing by allocating a message address space to every processing level, and deciding whether a reception authorization should be given to a reception part or not at a transfer address. CONSTITUTION:When a CPU part 13 receives a processing request signal 14, a message request processing is started, and a processing for a requested message is executed, and a flip-flop 19 is set with the completion of the processing. When a message transfer request arrives before a processing completion signal 151 is issued, a reception authorization signal 18 is not made significant by a gate 28, and a message reception is not performed. However, at such a time, when the address of level 0 at an internal memory 10 is represented as the transfer opposite message space address, the reception authorization signal 18 becomes significant from a gate 29 side through a gate 30, and a message receiving operation is performed, and the processing request signal is sent to the CPU part 13, then the message request processing being performed. Thereby, the message request processings of plural levels can be performed rapidly.

IPC: G01S17/93
Filed: 1992-09-30
Abstract: PURPOSE:To discriminate a vehicle from a rock surface, a forest or the like by a method wherein, after a noise is judged and when a measuring waveform rises or falls within a prescribed time, the waveform is not estimated to be the vehicle and, when the prescribed time is exceeded, it is estimated to be the vehicle. CONSTITUTION:Signals from a stop lamp SW 19, a turn signal SW 20, a between-vehicles-distance sensor 15 and a vehicle speed sensor 16 are input to an operation part 21 for a control unit. Detection signals from an accelerator opening sensor 17 and a shaft position detector 18 are input to a comparator 22. The operation part 21 detects the fall and the rise of a between-vehicles- distance signal as a waveform edge. After the signal has fallen and when it rises within a prescribed time, it is regarded as a noise. When the fall or the rise within the time of an alarm-stop preparation timer is detected, it is estimated to be an object other than a vehicle. When a pulse width up to the rise from the fall exceeds the prescribed time, it is estimated to be the vehicle and an alarm can be generated.

Title: Touch key
Inventor: MITSUNE SUSUMU
IPC: H03K17/972
Filed: 1987-10-20
Abstract: PURPOSE:To form a touch key excellent in service life, watertightness, durability and reliability by installing a plate of an oxide superconductor, a permanent magnet piece installed as opposed to this plate and a search coil installed between this permanent magnet piece and the plate all there. CONSTITUTION:A key part is a permanent magnet 2, and magnetic induction voltage is generated in a search coil 3 by pushing this magnet. When this key is left pushed intact, no induction voltage is generated, and when the key is pushed very slowly too, only very slight induction voltage is generated there, so that it is not so judged that the key has been pushed. Consequently, when a something is placed on a keyboard by mistake and so on, it is also not so judged that the key has been pushed. Restoring force of the key is secured by resilience between the permanent magnet and a plate of an oxide superconductor 1 to be opposed to this magnet. Since a mechanical contact point is not utilized, it is excellent in these aspects of service life, watertightness and durability and, what is more, since a spring type restoring system is not adopted, it is excellent in long service life and reliability as well.

Abstract: PURPOSE: To provide an inverter device which can be manufactured easily and in which the unbalance between the current of each section is reduced. CONSTITUTION: In an inverter device in which high-side switch/low-side switch separating elements are connected in parallel, first-group switching modules 3u, 3v, and 3w and second-group switching modules 3u', 3v', and 3w' are arranged on the flat surface of a substrate so that the power supply terminals of the switching modules of the same phase can become axially symmetrical to each other with respect to the center line 40 of the substrate. In addition, bus lines 1 and 2 respectively have main line sections 11 and 21 extended along the center line 40 and branch line sections 12 and 22 which are extended to the power terminals of modules (for example, 3u and 3u') from the main line sections 11 and 21 so that the sections 12 and 22 can become axially symmetrical to each other. Therefore, the fluctuation of an electric current between both modules can be prevented, because the voltage drops between the main lines sections 11 and 21 of the bus lines 1 and 2 and the power supply terminals of both modules become even.
