Title: Microphone mount structure for portable electronic device
Inventor: OKAWA TATSUYA
IPC: H04B1/3822
Filed: 1994-06-03
Abstract: PURPOSE:To provide a splash proof function to the structure and to obtain a microphone mount structure for the portable electronic device with excellent assembling performance by press-fitting a specific microphone cover to a recessed part formed to a case and press-fitting a microphone to the microphone cover. CONSTITUTION:A microphone cover 10 made of a high elastic resin such as silicon rubber is fitted to a recessed part 5 made with a rib 4. The outer diameter of the cover 10 is selected somewhat larger than the outer diameter of the recessed part and the cover 10 is press-fit to the recessed part 5. Then a microphone 6 is press-fit to the cover 10 through a water-proof sheet 13 and the microphone 6 is supported by the elastic force of the cover 10. Furthermore, when the cover 10 is fitted to the recessed part 5, each of pleats 11 is pressed into contact onto the inner face of the recessed part 5 and the pleats 11 act as sealing. Moreover, since the microphone 10 is press-fitted to the cover 10, the rib 4 and the cover 10 are in close contact with each other and a torus projection 12 is in press contact with the sheet 13 thereby allowing the torus projection 12 to act as sealing.

Title: Encoding system with reduced signal speed
Inventor: KINUHATA KOUJI
IPC: H04N1/21
Filed: 1981-09-17
Abstract: PURPOSE:To perform efficient, low-speed signal transmission by transmitting an output signal from a variable length equalizer at a specified bit rate through a transmitting buffer memory, and performing variable length encoding through a receiving buffer memory at a reception side. CONSTITUTION:An output signal from a variable length equalizer is stored temporarily in a transmitting buffer memory 5 and then sent out successively to a transmission line 7 at a specified bit rate. When the signal in the memory 5 (having L-bit capacity) decreases to L1 bits (L1<L), the transfer of the signal from a temporary memory 2 is stopped. When the amound of the signal in the memory 5 decreases to L2 bits (L2<L) as a result of the stopping of the transfer, this stopping is reset. Thus, an output bit array is held invariably constant through the memory 5. At a reception side, on the other hand, a received signal is applied to and stored in a receiving buffer memory 9 to be sent out to a variable length decoder 10. This signal is decoded into a normal variable length code, which is stored in a temporary memory 11 and also sent out to a VTR12 successively.

Title: Electronic clock
Inventor: MAEDA HIDETOSHI
IPC: G04G5/00
Filed: 1980-10-16
Abstract: PURPOSE: To simplify the structure of a switch for simplifying time correction and a return operation to a normal operation by a process wherein three sets of momentary push switches corresponding to the respectively differentiated functions are made to make an interrelating operation for setting a time.  
     CONSTITUTION: With every push on a momentary push switch S 1  the mode selection output generates from the mode change-over circuit 11 having a ring counter and such built-in and when the data correction mode and such select a data figure and such of the indication circuit 17, the and gate 37 switches "off". And, so long the momentary push switch S 3  is pushed on, the and gate 38 switches "off" through the and gate 37 and the data counter 40 counts the 1Hz signal coming through the NOR gate 39 to do the desired set of date. Next, the momentary push switch S 2  for forced return is operated to reset the circuit 11 for returning to the normal operation. The above is the same to the figures hour, minute and second, thus with the operation easy to memorize by means of the combination of switches of simplified structure the time correction and such as well as the return to the normal operation can be done simply and surely.

IPC: G02B6/32
Filed: 1988-06-15
Abstract: PURPOSE:To obtain the optical beam collimator which allows easy assembly and has the high accuracy of the exit optical axis of a light beam by inserting an optical fiber into the collimator body in such a manner that the end face thereof is positioned at the mid-point of a hollow shaft hole. CONSTITUTION:The collimator body 20 consists of a transparent member, for example, glass, which is approximately bar- or circular cylinder-shaped over the entire part. One end face thereof forms a spherical surface 21 projecting outward. The hole 13 having the bore nearly equal to the outside diameter of the optical fiber 1 is provided thereto from the other end face 22 to the focal position of the spherical surface 21 along the central axis. The light beam emitted from the end face of the optical fiber 1, therefore, advances in the collimator body 20 while spreading gradually along the axis of the collimator 20 and is converted to the parallel light beams around the axis of the collimator body by the spherical surface 32 of the one end face. The parallel beams are radiated to the outside. Since the collimator body 20 itself constitutes the mounting part to the device, the accuracy of the exit optical axis is extremely high and the mounting without adjustment is possible.

Title: Tracking device of video tape recorder
Inventor: TANAKA SHIGEO
IPC: G11B15/467
Filed: 1983-08-11
Abstract: PURPOSE:To reduce the S/N deterioration of a picture plane even in case reproduction of a tape pattern inferior in linearity by giving priority to the tracking at the center part of a reproduced picture plane to perform the tracking of a rotary magnetic head. CONSTITUTION:A mono-multi 32 outputs a pulse in synchronous with the rise and fall of a head switching pulse. Thus a monostable-multivibrator 33 produces a gate pulse which is fed to a gate circuit 31. The circuit 31 transmits the output of a voltage comparator 21 for the period of said gate pulse and supplies it to an integration circuit 34. An operational amplifier 35 calculates the outputs of an AFC (automatic frequency controller) and an APC (automatic phase controller). These outputs are supplied to a capstan motor 38 via a motor driving amplifier 37. As a result, the motor 38 drives a tape so that a magnetic head scans correctly a recording track. For the output of the comparator 21, the output at the center of a picture plane is gated and the servo is applied. As a result, the tracking error is reduced at the center part of the picture plane. This improves the S/N of a reproduced picture plane.
