Title: Video signal correction circuit
Inventor: NOHARA KAZUTOMO
IPC: H04N5/66
Filed: 1988-11-19
Abstract: PURPOSE:To improve the accuracy of inverse gamma correction with simple offset adjustment by providing a differential amplifier amplifying an input video signal and outputting the result, a comparator comparing an output video signal with a reference signal and a bias offset means or the like. CONSTITUTION:Each base of a transistor(TR) 14 in a comparator B and a TR 20 in a differential amplifier C is connected to an output terminal 29 and an input terminal 30 and a TR 32 as a bias offset means is provided to a common collector path of the TRs 19, 20. Then the input video signal is subject to DC restoration so that the pedestal level reaches a level of a reference signal by a holding voltage based on the difference between a voltage VO of an output video signal at a terminal 29 and a reference voltage Vref for the base voltage of the TR 13, and the signal and the reference signal are inputted to bases of TRs 19, 20. Based on the limit of the collector current of the TRs 19, 20, the offset of the base bias is set so that the operating range of the amplifier C is within a range of inverse gamma correction of the TRs 19, 20. Thus, the inverse gamma correction with high accuracy is attained with simple offset adjustment.

Title: Mirror driving device
Inventor: MATSUMOTO TOSHIRO
IPC: G03B19/12
Filed: 1987-11-20
Abstract: PURPOSE:To prevent the elevation start timing and lowering start timing of a mirror from having variance by unlocking a mirror position by the same locking and unlocking member when the mirror is elevated and lowered. CONSTITUTION:A 1st lock member 6 for locking the mirror at a lower position and a 2nd lock member 14 for locking the mirror at an upper position are locked and unlocked through the operation of the same locking and unlocking member 5. Therefore, 'up locking release force for mirror' is equalized to 'down locking release force'. Consequently, the setting of the start timing of mirror elevating operation and the start timing of mirror lowering operation are facilitated, the number of components is decreased, and the structure is simplified.

Title: Method and circuit device for loading initial program loader to secondary computer
Inventor: DEIITAA KOTSUPU
IPC: G06F9/44
Filed: 1987-11-20
Abstract: A second computer (RE2) is connected via a common memory (M) to a main computer (RE1). 
<??>For the initial program loading of the second computer (RE2) an initial program loader is stored in a mass memory (MSP) of the main computer (RE1) instead of, as usual, in a start routine memory. 
<??>The main computer (RE1) loads the initial program loader into the common memory (M), applies a restart command to a central processing unit (CPU2) of the second computer (RE2) and then selects a memory access logic (SZL) in such a manner that all program memory access commands coming from the central processing unit (CPU2) are rerouted to the section of the common memory (M) in which the initial program loader is stored until the second computer (RE2) has read out the initial program loader. The memory access logic (SZL) then receives an acknowledgement signal from the central processing unit (CPU2), as a result of which the memory access logic (SZL) conducts all further program memory access commands of the central processing unit (CPU2) to a program memory (MP2) of the second computer (RE2).

Title: Image display device
Inventor: TANIGUCHI TAKASATO
IPC: G02F1/13
Filed: 1993-10-29
Abstract: PURPOSE:To enhance the fineness and luminance of the device while reducing the size over the entire part thereof and to enable observation at a wide visual angle by constituting a display element of a liquid crystal element of a reflection type at the time of macroobserving display information as a virtual image. CONSTITUTION:The display element 5 consists of the liquid crystal element of the reflection type. The luminous fluxes from a light source 1 of a fluorescent lamp are converted to approximate parallel luminous fluxes 3 by a reflection plate 2 of a proper shape. These fluxes are made incident on a polarization beam splitter 4. Further, the incident polarized light beams on the liquid crystal element 5 are modulated only at the points 5-1 to 5-3 where the images are displayed. The incident polarized light beams pass the polarization beam splitter 4 as the luminous fluxes 7-1 to 7-3 of the display information of the reflected polarized light having the orthogonal planes of polarization. These luminous fluxes are converted by the lens system 8 to the luminous fluxes (7-1)' to (7-3)' which are made incident on the observer's pupils 9. At this time, observer feels as if he views the luminous fluxes (7-1)'' to (7-3)'' from the points (5-1)' to (5-3)' on the virtual image plane 10. The observer is thus able to observe the display information displayed on the small-sized liquid crystal element 5 as the virtual image of a large screen.

Title: Leak confirming device for gas-solution charged container
Inventor: ENDO TOKUO
IPC: G01M3/24
Filed: 1989-11-13
Abstract: PURPOSE:To convey the container fast by supplying liquid between the vibration surface of an ultrasonic wave irradiating device and the gas-solution charged container when the gas-solution charged container is irradiated with an ultrasonic wave. CONSTITUTION:Water 9 falls down from the lower opening 12 of a water tank 11 at all times and flows along the slanting surface 7 of a box 6 to between a beer bottle 1, which is conveyed while positioned, and the vibration surface 8; and the water falls down while forming a layer of several mm in thickness between the bottle 1 and vibration surface 8, and is received by a lower container 17. Thus, while the water 9 is present between the bottle 1 and vibration surface 8, the ultrasonic-wave irradiating device 3 irradiates the bottle 1 with the ultrasonic wave. Consequently, a leak in the bottle 1 can be decided from the height of bubbling in the space part 18 in the bottle 1, which is only applied with the water 9, so the bottle 1 set on a conveyor 2 can be conveyed fast.

Title: Magnetic disk
Inventor: OKAMOTO KAZUHIRO
IPC: G11B5/73
Filed: 1997-10-27
Abstract: PROBLEM TO BE SOLVED: To lessen warpage and to obtain stable output with a head floating type recording system by incorporating acicular magnetic powder of an acicular ratio within a specific range into nonmagnetic powder in forming magnetic layers contg. the magnetic powder on intermediate layers contg. the nonmagnetic powder. SOLUTION: The magnetic layers 4, 5 for higher density recording of the magnetic disk provided with the intermediate layers 2, 3 between a nonmagnetic base 1 and the magnetic layers 4 and 5 are formed thin and the intermediate layers 2, 3 are formed thick and, therefore, the conditions of the acicular powder in the intermediate layers 2, 3 affect the occurrence of the warpage of the magnetic disk. Then, the warpage of the disk is suppressed by specifying the acicular ratio of the non-management powder to 10 to 30 and generating the resistance force against the warpage. The nonmagnetic powder having the high acicular ratio of >=10 in the acicular ratio is capable of suppressing the warpage even if the nonmagnetic powder is aligned to some extent in a coating stage.  At the acicular ratio above 30, the tendency to the flocculation of the nonmagnetic powder particles to each other increases and the resistance force against bending lowers.

Meanwhile, a rule which finds fitting in a condition this time is selected out of the rules which find the channel working ratio from the size of the wirable area, the total number of nets, the total number of pins, and it is sent to the channel working ratio prediction part 202. In such a way, it is possible to realize the prediction with high accuracy, and to shorten a time until the arrangement and wiring result which satisfies the delay condition can be obtained.
