Title: Camera controller
Inventor: FUTAGAWA YOSHIKIYO
IPC: G03B7/08
Filed: 1977-12-23
Abstract: PURPOSE: To facilitate controlling of quantity of light of a camera by using liquid crystal.  
     CONSTITUTION: A liquid crystal body 3 consisting of polarizing plates 23a, 23b and transparent plane substrate pair 20a, 20b holding liquid crystal 21 via spacer 22 and having transparent electrodes is disposed between an objective lens 2 and a shutter 4 and is connected to a control circuit 12. Then, the output of a light quantity detector 15 which detects the brightness of the outside world such as of the subject 1 or the like is inputted to the control circuit 12, by which voltages are selectively applied to the segmented transparent electrode groups of the liquid crystal body 3 and at the same time opening and closing of the shutter 4 are controlled. This causes the quantity of transmission light to be controlled according to the quantity of the light of the outside world and nearly a fixed quantity of light to be radiated to a photosensitive film 5. As a shutter button 7 is depressed to close a switch 10, the control circuit 12 is connected to a power source 11 before the shutter 4 is actuated by a shutter actuating means 8.

Title: Low-pressure discharge lamp and its lighting device
Inventor: NISHIMURA KIYOSHI
IPC: H01J61/56
Filed: 1994-07-07
Abstract: PURPOSE:To simplify the constitution of an electrode and get ignition of brilliance being equal over wide area by discharging the accumulated charge at the surface of a dielectric into air, according to the inversion of polarity between electrodes. CONSTITUTION:When pulse voltage is applied between electrodes 6 and 8 from an oscillator 10, in case that the electrode 6 becomes a + pole, for a dielectric 7, the face opposed to the electrode 6 is polarized to - and the face opposed to the electrode 8 is polarized to +, and electrons are charged to the surface of a ferroelectric exposed in the discharge space 3 by an exposer 9. Next, when the electrode 6 is inverted into - pole, for the ferroelectric 7, the face opposed to the electrode 6 is polarized to +, and the face opposed to the electrode 8 is polarized to -, and the polarity is inverted. Therefore, the electrons accumulated on the surface of the ferroelectric 7 exposed in the space 3 are discharged to the side of the space 3, being repelled by the polarization on -side of the ferroelectric 7.

Title: Method and device for image forming
Inventor: MASUDA TOSHIYA
IPC: H04N1/40
Filed: 1992-05-22
Abstract: PURPOSE:To improve the gradation of print by selecting the gradation pattern of plural picture elements corresponding to inputted one-picture element multigradation picture data and performing the varyiable processing of the printed picture element density and converting picture data to an integer multiple resolution of one picture element, thereby substituting the picture data with the gradation pattern. CONSTITUTION:An input data processing part 102 separates only picture data of inputted one-picture element multigradation data Dm and stores the picture data in an image buffer 105. A resolution conversion part 104 extracts a character image from a CG ROM 103 and expands it on a frame memory 108. Thereafter, a gradation pattern selecting part 106 takes out data Dm stored in the buffer 105 and selects a gradation pattern corresponding to data Dm from a gradation pattern storage memory 107 and expands it on the memory 108. A print processing part 110 prints out picture data, which is enlarged (n) times ((n) is an integer) and is reconstituted on the memory in such manner, with the resolution set by a printing resolution setting part 111. Thus, the gradation of the print is improved.

Title: Oscillometer method blood pressure monitor utilizing non-uniform attenuating chip
Inventor: MEINAADO RAMUZEI ZASAADO
IPC: A61B5/02
Filed: 1986-07-04
Abstract: The deflation of the inflatable and deflatable cuff worn by a subject during automatic sphygmomanometric measurement is accomplished in unequal size decrements and principally in larger steps than 7 Torr. Each step after detection of the initial oscillations is determined in the first instance by reference to a look-up table or en equation as a function of prevailing cuff pressure. This Base Step dimension is augmented by a factor proportional to the last oscillation amplitude, the factor being increased after detection of the maximum oscillation amplitude. A valve mechanism with at least two different effective orifice sizes is used for deflation, the smaller size effective orifice being used first, to maintain control over the decrement step rate while holding the time for decrement within a predetermined limit of 8 mSec. per Torr, i. e., maintaining the rate above 125 Torr per second. The valve mechanism can consist of two valves with unequal orifice size, or it can consist of two equal orifice size valves to be used singly for providing the effective smaller orifice, or in parallel to provide the effective larger orifice. Alternatively a single variable orifice valve can be used.

Abstract: PURPOSE:To increase the processing speed of a computer by separating the data transfer routes from each other among a CPU, a magnetic memory device and a memory system and therefore avoiding such a case where the data transfer to be carried out at one side is kept waiting for the data transfer at the other side. CONSTITUTION:The data are transferred between a CPU 1 and a memory system 3 via a random access terminal 5 of a memory element 4 and an internal bus 7a. While the data are transferred between a magnetic memory device 2 and the system 3 via a serial access terminal 6 of the element 4 and a bus 7b. Thus the data transfer routes are separated from each other among the CPU 1, the device 3 and the system 3. A controller 8 reads data out of the terminal 6 of the element 4 to transfer it to the device 2 and at the same time transmits a control signal 9 to transfer data from the device 2 and to write it to the terminal 6.
