Title: Phase difference voltage generating circuit
Inventor: YAMAMOTO TAKESHI
IPC: G11B7/09
Filed: 1996-03-15
Abstract: PROBLEM TO BE SOLVED: To provide an integration circuit by the sequential transferring of electric charges with which a sufficient performance is obtained even in the occurrence of a tracking error in reproducing optical disks such as DVD(digital video disk) in which high accuracy and high-speed property are required. SOLUTION: When only one side of corresponding edges of two digital inputs comes in this circuit to charge a primary capacitor C1, a transistor Q1 is turned OFF by turning a switch for electric charge transfer SW1 to a grounding side and when an edge becoming a pair comes in and the detecting of phase difference information is completed. the switch SW1 is quickly turned to a bias voltage Vb side to make the transistor Q1 operate and the charged electric charges are transferred to a secondary capactor C2 to obtain integrated information of the phase difference between inputs 1, 2. When the transfer is completed, the capactor C1 is initialized by Vb -VBE (VEB is the voltage between the emitter and the base of the Q1 at the time that the Q1 is ON).  Thus, a high-speed operation is made possible and an error is made to be small by using one piece of an NPN transistor in a base ground mode in the transferring of the electric charges.

IPC: H04N9/07
Filed: 1998-02-25
Abstract: PROBLEM TO BE SOLVED: To interpolate the relevant color signal of a pixel string which does not include the pixels of a certain color signal and to decrease the false color signals that occur at the boundary parts of an object image, by extracting an interpolation signal obtained through multiplication of the coefficient signals corresponding to the levels of 1st and 2nd low frequency signals by each other, using the extracted interpolation signal as a signal existing at the position of a 1st pixel. SOLUTION: First and 2nd low frequency signals, corresponding to a 1st pixel position, are extracted from the signal obtained by adding together the signals of each prescribed pixel. Then an interpolation signal obtained by multiplying the coefficient signals, corresponding to the levels of the 1st and 2nd low frequency signals by each other, is extracted and used as a signal existing at the 1st pixel position. That is, the low frequency components of R and G signals are extracted from the outputs of a solid-state image-pickup device 1 and a 1H delay circuit 15 and is added to a divider 8 to obtain a signal that corresponds to the ratio set between both signals with regard to this camera.  Then the obtained signal is multiplied by the G signal obtained from an 1H delay circuit 14 by a multiplier 9 and selected by a gate circuit 25 to have the R signal of a pixel string including no R pixel interpolated.

Abstract: PURPOSE: To obtain a liquid fuel combustor with such a construction that a wick is lowered and shut up without producing any raising flame by changing wick lowering speed step by step with the wick braked at a preset stage of the lowering by means of a brake bead.  
     CONSTITUTION: The counterclockwise turn of an operating shaft 37 which is transmitted to a driving disc 29 idles the long hole portion (b) of a long hole 30, centripetally transfers a driving shaft 20 at the small portion (a) of the hole 30 while lowering a wick 7, and after lowering the wick 7 closes the passage of the wick 7 with a shutter plate 16. Therein, while the brake spring plate 63 of a guide plate 5 and the projecting portion 64 of the disc 29 remain in contact with each other, the reversion force of a spring 51 is weakened so that the wick lowers slowly. When the projecting portion 64 has come off the plate 63, the wick 7 lowers smoothly and the shutter piece 25 of the plate 16 advances inward through a clearance 24 to securely shut the passage of the wick 7.

Title: Retouching solution for electrophotographic toner
Inventor: FURUKAWA MASATO
IPC: G03G21/00
Filed: 1978-05-18
Abstract: PURPOSE: To enhance performance for erasing toner images, to reduce retouch traces left in the area retouched, and further to reduce whitening phenomenon whitening in the retouched area after retouching, by combining 2 kinds of specified liquid.  
     CONSTITUTION: A white pigment fine powder, such as silica is added to a liquid consisting mainly of a multivalent alcohol poorly dissolving a resin contained in an electrophotographic toner, such as ethylene glycol. Such liquid is coated and acts on the toner image like masking. Diffusion into paper by the poor solvent is small. Next, a good solvent for the resin contained in the above toner is coated. The coated poor solvent hinders the good solvent from diffusing into the paper, resulting in no penetration through the paper, permitting the resin contained in the toner not to be dissolved and the toner fine particles not to be isolated, accordingly, not to penetrate the paper. Thus, retouching traces are not left.

Abstract: PURPOSE:To make it possible to know the smoothness of a shifting operation quantitatively, by evaluating the smoothness of the shifting operation on the basis of a work load applied on a shift lever at the time of a second increase in a load. CONSTITUTION:A large load acts on a shift lever at the time of the synchronous operations of a sleeve 4 and a gear spline 7 in a shifting operation and the subsequent thrusting-through operations of the sleeve 4 and a spline chamfer of a synchronizer ring 9, and thereafter this load once decreases and then increases again at the time of the thrusting-through operations of the sleeve 4 and a spline chamfer of the gear spline 7. On the occasion, a work load applied on the shift lever at the time of this second increase in the load is determined. Based on the work load applied on the shift lever at the time of the second increase in the load, accordingly, the smoothness of the shifting operation is evaluated, and thereby the result of evaluation reflecting well the feeling of the smoothness given to the hand of a man can be obtained quantitatively.

Abstract: PURPOSE:To economically attain a method transferring large capacity data to a parallel at high speed via plural transmission lines. CONSTITUTION:A transmission side counts up the transfer request from a host device by a transfer number of time counter 2. Transmission side conversion modules (3-1 to 3-L) read the transfer data for which the transfer request is performed from a transmission side data register 1, evenly divide the data into plural transmission lines 105 and transfer the data as serial data with count up information. On a reception side, reception side conversion modules (4-1 to 4-L) convert the serial data from the plural transmission lines 105 into each parallel data. A reception side data register 5 composes the transfer data for which the original transfer request is performed by the divided transfer data included in each parallel data only when all of the count up information in a transfer number of time check circuit 7 are matched.
