Title: Picture forming device
Inventor: NAKANO MASAO
IPC: B41J2/52
Filed: 1991-07-05
Abstract: PURPOSE:To obtain a proper picture in accordance with an original picture by designating the level of a luminance signal corresponding to the maximum black density of an output picture, and setting the size of a density signal variably by allowing it to correspond to the size of this level of the luminance signal. CONSTITUTION:A designating means 1000 instructs the level of the luminance signal based on the maximum black density. A signal processing means 1100 converts relatively the luminance signal into the density signal so that the designated level of a second luminance signal corresponds to the maximum black density level of the density signal. Thus, since a density reproduction range can be set variably according to the kind of the original picture, the favorable quality of the output picture can be obtained according to the kind of the original picture.

Title: Dropout detection circuit
Inventor: OGAWA YOSHIZO
IPC: H04N5/94
Filed: 1984-08-08
Abstract: PURPOSE:To simplify the circuit constitution and to detect a dropout having different reproducing speeds in a single circuit by integrating both a correction signal caused by kicking and that by defects at a high speed reproduction so as to compare them. CONSTITUTION:A reproducing device reproduces a disk at normal speed or high speed to generate a dropout pulse as a correcton signal, and supplies it together with a high frequency signal to a dropout detector 3. It integrates said pulse in a charging/discharging circuit 7 to form a signal (b). Said signal (b) obtained by integrating dropout pulses a1 caused by kicking is biased to a voltage Ea, and on the biasing, an integral waveform of the dropout pulse due to defects is overlapped. A comparator 6 compares the voltage of the signal (b) with a reference voltage E1. When the signal (b) > voltage E1, said comparator 6 generates a detection signal (c). Thus, since the dropout pulse, where the pulses a1 and a2 are mixed, is directly supplied, the removal of the pulse a1 becomes unnecessary, and the circuit constitution is simplified accordingly.

Filed: 1988-07-04
Abstract: PURPOSE:To detect the fail of pattern matching and to execute useful pattern matching by adding an identification data (ID) arithmetic unit including an auxiliary information part to a data arithmetic unit. CONSTITUTION:A controller 5 transfers pattern list ID data #1 from a memory device 1 to one R#1 of plural registers 3 in the data arithmetic unit 4 and stores the data. Data list ID data #2 are similarly transferred to one R#2 of the registers 3 and stored. The ID data arithmetic unit 2 compares the auxiliary information parts of the ID data #1, #2 stored in respective registers R#1, R#2. The number of elements of the list data is stored in each auxiliary information part. When both the information parts are different as the result of comparison, pattern matching is apparently failed, so that the succeeding processing is not executed.

Title: Collision sensing apparatus in vehicle
Inventor: OKADA MOTOHIRO
IPC: B60R19/32
Filed: 1979-12-20
Abstract: PURPOSE:To actuate a crew restriction apparatus by a method wherein a speed change at a collision is detected as an attenuation force generated by a damper, and a collision energy is detected as a deformation quantity of an impact energy absorption member and further, when the detected quantity exceeds a constant value, a switch is actuated. CONSTITUTION:When a traveling automobile causes a collision which generates a speed variation more than a certain value, then, first, a front bumper 2 retreats receiving a collision load and a damper 3 makes a movable piston 5 withdraw into a fixed cylinder 4 and further, generates an attenuation force against the retreat movement of the front bumper 2. As a result, the load imposed on the fixed cylinder 4 is borne by an impact energy absorption member 9. When the attenuation force exceeds a defined value, the cylinder 4 retreats along with an acceleration sensing switch 14 while giving a deformation to a member 9. When the acceleration exceeds a given value, a weight 17 of the switch 12 separates from a magnet 19 and it rotates forward to contact with both contacts 18, 18'. With this, the switch 12 is turned ON, and a crew restriction apparatus operates, thus, rapidly, restricting an  inertia movement of the crew.
