Abstract: PURPOSE:To enable a time correction through simple operation by providing a photosensing element at the transmissive part of a digital display part corresponding to a segment, and by generating a correction signal by a driving circuit of the segment according to light and shade of a light. CONSTITUTION:First, a correction signal detecting circuit is so set that, for example, display OUTPUT ''1'' when first 2Hz and then 1Hz which are not diffucult to  be generated in general are INPUT in order. At this time, if light to photosensing  element 6h is shut out at the same intervals with pulses set to the correction signal detecting circuit that corresponds to photosensing element 6h, the correction signal  detecting circuit OUTPUT ''1''. Thus, a signal of a number is INPUT to a seven  segments-BCD converting circuit by shading light from photosensing elements 6a- 6g that correspond to segments of the number to be corrected. On the completion of  the correction of one number, the next number is corrected similarly. In this constitution, time correction is made only by shutting out light incident to the front surface of the timepiece.

Filed: 1986-01-31
Abstract: PURPOSE:To increase the retrieving time for plural files and to improve the system reliability by recording the file information directly to a single block or plural blocks and also recording the retrieving items collectively by an amount equal to plural files. CONSTITUTION:The file structure of a postscript type recording device includes a volume label area 7, a file label area 8, an index label area 9, and plural file areas 10a, 10b....

Filed: 1985-02-01
Abstract: PURPOSE:To obtain a video signal processing device which can use effectively the number of quantizing steps of an A/D converter by digitizing the signal part only excluding a synchronizing signal when an analog video signal is digitized. CONSTITUTION:An analog video signal 100 inputted from an input terminal 501 goes to be a signal 101 while it is clamped at a clamping circuit 2. Here, the circuit 2 fixes the direct current level of the signal so as to code a pedestal level to ''0001'' and a white 100% level to ''1111'' by an A/D converter 3. As the result, to the dynamic range of the converter 3 only the video information part excluding the synchronizing signal is assigned. A signal 102 A/D-converted by the converter 3 is guided to a synchronizing signal coding circuit 5, and the signal of ''0000'' is clipped to ''0001'' by a clipping circuit 6 in the circuit 5. Further, for the signal 103 in a synchronizing adding circuit 7, the synchronizing signal part is coded to ''0000'' and a signal 105 is obtained by matching with the timing of a synchronizing signal 104 separated by a synchronizing separating circuit 4.

IPC: G11B15/10
Filed: 1987-01-30
Abstract: PURPOSE:To obtain a compact tape recorder at low cost by conducting the follower start of the follower member of a cam corresponding to each working motion by the operation of the time according to each working mode of a solenoid. CONSTITUTION:The conduction of the follower start of the follower member 5 or 6 of cams 8-10 corresponding to each working mode is by the operation of the time corresponding to each working mode of a solenoid 1. The driving transmission means 12 of each working mode can therefore be shifted to a means 13 or 15 at driven side only by controlling the working time of one solenoid 1. Namely the driving transmission means 12 of each working mode can be shifted only by controlling the working time of one solenoid 1. The tape recorder using this device thus becomes extremely compact and yet inexpensive because of numerous solenoids being unnecessary.

Abstract: PROBLEM TO BE SOLVED: To provide an end structure on the opening side of bottom wall excellent in strength in which step is eliminated for the convenience of cleaning. SOLUTION: A downward bend 12 is formed at the front edge of an inner bottom plate 11 and a front plate 16 is bonded to the front edge of an outer bottom plate 13 while standing thereon. They are made of a stainless steel plate. A setback part 21 is formed at the upper end of the front plate 16 and received on the rear side of the bend 12. A synthetic resin spacer 24 is inserted between the inner bottom plate 11 and a clamping part 22 formed at the upper edge of the offset part 21 while directing inward and tightened by means of a rivet 25. A bottom wall 10 is formed by filling the space between both bottom plates 11, 13 with a heat insulating material 34. Cleaning is facilitated because a standing part is not present at the lower edge of an inlet/outlet 2 and receiving strength is enhanced because a load is received at a tightening part 38.  Thermal conductin can be prevented by means of spacer 24.
