Title: Image pickup device
Inventor: TAKAHASHI KOJI
IPC: H04N5/235
Filed: 1987-06-09
Abstract: PURPOSE:To substitute a signal having a part of inappropriate exposure amounts with a signal of a picture element part corresponding to a part obtained by picking up an image with different exposure amount, and to obtain moving pictures with virtually wide dynamic range by accumulating plural video signals of different exposure amounts temporarily. CONSTITUTION:A direct output from an image pickup element 103 is herein called a through image, and signals in the preceding field that are temporarily stored in an image memory 204 are called a memory image or a memory output. Of the through image, the image of a main object at the time of halation is painted black in every odd numbered field, while the background is partial void in every even-numbered field. Since a memory image is made of signals that are delayed for one-field length, a partial void and a black painting are generated in fields other than those of a through image. Hence by suitably combining a through image and a memory image, a partial video that includes no void or black painting can be obtained. That is, in every field, the signals of a through image and a memory image are compared with a prescribed thresh old, making them '1' when larger than the threshold, but '0' when smaller in order to decide on a partial void or black-painting for every picture element.

Title: Radiation detector
Inventor: TAMURA MASAKAZU
IPC: G01T3/00
Filed: 1989-06-08
Abstract: PURPOSE:To measure a neutron flux level over a wide range by providing a meshed second cathode electrode. CONSTITUTION:A meshed second cathode electrode 7 is disposed between a cathode electrode 1 and an anode electrode 2 in such a manner as surrounding the anode electrode 2. While a radiation level is low, a current I is small and the radiation detector operates as an ionization chamber utilizing the anode electrode 2 and the cathode electrode 1, but Vs will not increase because of the current I being small. While the radiation level is high, the current I is big but the meshed second cathode electrode 7 is utilized in place of the cathode electrode 2 and so the gap length becomes about half that of the anode electrode 2 and the cathode electrode 1 and Vs will not increase so much.

Title: Kanji converter
Inventor: AOKI TOSHIHISA
IPC: G06F17/22
Filed: 1987-06-09
Abstract: PURPOSE:To decrease the possibility for production of funny compound nouns and to improve the correct converting rate, by excluding a word consisting of a single KANJI (Chinese character) in terms of a component element of a compound word. CONSTITUTION:A compound noun retrieving part 5 checks whether the given Japanese reading of KANJI can be divided into plural nouns or not while matching with an independent word dictionary 6. In this case, such a compound noun that includes a noun consisting of one KANJI in its component element is excluded out of the candidates of conversion even if the corresponding reading can be divided into plural nouns. Thus the output frequency of funny compound words is decresed for the candidates of conversion. Then the input job efficiency is improved for Japanese words.

Title: Time measuring instrument
Inventor: YAMAGUCHI YUJI
IPC: G04F10/10
Filed: 1987-06-11
Abstract: PURPOSE:To make stable time measurement by controlling signals to be measured and reference clock so as to synchronize the same. CONSTITUTION:The signals A1, B1 to be measured are inputted to a gate 3 and are impressed as the signals A2, B2 delayed respectively by time tau2 in delay lines 1, 2 to a time difference measuring circuit 4. The output signal C of the gate 3 is used as the stop signal C to stop the oscillation operation of a voltage control oscillator 8. The signal C is delayed by time tau1 in a delay line 7 and is used as the start signal D to start the oscillation operation of the oscillator 8. The oscillation of the reference clock SC is stopped in synchronization with the signal C and the loop is opened by a switch 13 to start the oscillation in synchronization with the signal D. The voltage at the time of a lock state is applied to the oscillator 8 which outputs the clock SC of the specified period. The signals A2, B2 and the clock SC are so controlled as to be synchronized in the circuit 4, by which the phase differences of the signals A1, B1 and the clock SC are prevented from changing. The stable time measurement without having a fluctuation in the time difference is thus executed.

Abstract: PURPOSE:To prevent the breakage of a form and the scatter of toner when jamming, etc., happens by reducing the press-contacting force between a heat roller and a pressure roller according to the opening of an upper frame and releasing a rotation transmission mechanism for a roller from a driving source. CONSTITUTION:When the upper frame 2 is opened at the time of executing a maintenance job since the jamming happens, the press-contacting force between the heat roller 6 and the pressure roller 8 is reduced, and also the rotation transmission mechanism from the driving source such as a main body motor, etc., is separated from the rotation means of the heat roller 6. Then, the resistance of rotation between the heat roller 6 and the pressure roller 8 is made smaller and the form 14 can be drawn out with a slight force while the heat roller 6 and the pressure roller 8 are rotating in a contact state, if the form 14 which is put between the heat roller 6 and the pressure roller 8 is drawn. At such a time, the application of current to the heating means of the heat roller is cut, but the unfixed toner can be fixed with remaining heat. Thus, the scatter of the toner on the form 14 to the main body 1 can be prevented.
