Title: Speaker system
Inventor: MIZUNO MASAYUKI
IPC: H04R1/02
Filed: 1982-06-18
Abstract: PURPOSE:To attain a cost reduction of a speaker system, by cutting off a sub- baffle plate of a different length-breadth size from the sub-baffle and then attaching the sub-baffle plate to the baffle plate. CONSTITUTION:A sub-baffle plate 5 is cut off from a wooden baffle plate 4 having a different length-breadth size from the plate 5 by means of a router, etc. Then an attachment hole 6 for speaker unit 3 is drilled to the cut-off plate 5. This plate 5 is turned 90 deg. and attached to the original plate 4. In this case, a gap 7 is produced between the plates 4 and 5 owing to their different sizes. This gap 7 is used as a bass reflex port. The bass reflex quantity can be easily controlled just by changing the size of the plate 5 and the attaching way of the plate 5 respectively. In addition, the way of attaching plate 5 creates the new feeling of design for a speaker system.

Title: Memory integrated circuit
Inventor: ARAI MITSUYOSHI
IPC: G11C17/18
Filed: 1990-04-19
Abstract: PURPOSE:To prevent unnecessary charging/discharging by adding an address holding circuit and a match detecting circuit and keeping a ROM in the charged state for the period when the same address signal is continuous. CONSTITUTION:When a precharge signal 7 is '0', an address signal 2 is changed and is fetched into an address holding circuit 13 by a latch pulse 8. The output of the address holding circuit 13 is inputted to a match, detecting circuit 9 together with the new address signal 2 changed by the next precharge signal 7. When the preceding address and the current address are equal to each other, address match is decided, and a control signal 11 keeps '0' for this period of address match and a ROM 3 is kept in the charged state. Consequently, the ROM 3 stops the operation and the charging/discharging current does not flow. Since a control signal 12 is '0' also as it is, a data holding circuit 5 holds preceding data though the output of the ROM 3 is broken. This state is kept until the match detecting circuit 9 detects unmatch between addresses.

Title: Production of magnetic recording medium
Inventor: YAMANO MINORU
IPC: G11B5/852
Filed: 1983-06-10
Abstract: PURPOSE:To improve the surface smoothness of a magnetic layer and to reduce the variance of output level by leading a base film into and out a magnetic field formed by revolving a magnetic field generating means or shifting endlessly in locus said means with revolution so that the magnets of the same polarity are set opposite to each other in the vertical direction. CONSTITUTION:Roll magnets 7 and 8 for orientation are revolved at the same speed in the directions shown by arrows A and B. Many magnets 71 and 81 are set so that the same polarities are always set opposite to each other on the basis of a base film 2. As a result, a magnetic field parallel to the lengthwise direction of the film 2 and another magnetic field parallel to the width direction of the film 2 and another magnetic field parallel to the width direction of the film 2 are applied repetitively at any position of a coated film 6 on the film 2 and within the surface of the film 6. Then the orientating direction is corrected to the magnetic powder particles orientated in the lengthwise direction of the film 2 while a magnetic coating material is applied. As a result, the magnetic powder particles in the film 6 have no orientation, and the square forms are almost equal to each other between the lengthwise and width directions. Such a film is dried up and then blanked into a circular shape to obtain a magnetic disk. Thus a considerable variance of the output level is eliminated with this magnetic disk when the record/reproduction is carried out in the circumference direction of the disk. In such a way, the electromagnetic conversion characteristic is improved.
