Title: Gas bearing
Inventor: WATANABE KENICHI
IPC: F16C17/10
Filed: 1998-03-20
Abstract: PROBLEM TO BE SOLVED: To improve the shaft rigidity in the radial direction, to improve the shaft rigidity of a compression-floating type thrust gas bearing, and to increase the service life due to the reduction in friction in a floating condition from a low speed range by improving these characteristics. SOLUTION: When a rotor 21 is rotated, the gas is sucked from a suction hole 23 inside a bearing to increase the internal pressure of the bearing, the radial dynamic pressure by a dynamic pressure generation groove is increased to increase the radial shaft rigidity. In addition, the gas trapped between an upper part of a fixed shaft 18 and the rotor 21 is further compressed, the gas pressure in the thrust direction is increased to increase the thrust bearing rigidity. As a result, the contact time of the rotor 21 with the fixed shaft 20 is shortened by floating the rotor 21 from the low speed range, the maximum PV value in the contact condition at low speed is reduced to generate the friction, or to retard the progress thereof, and the service life can be increased.

Title: Method for reserving and recording broadcast program
Inventor: KIMURA TAKESHI
IPC: H04N21/482
Filed: 1999-03-17
Abstract: PROBLEM TO BE SOLVED: To record a reserved designated program in a complete form as much as possible despite the occurrence of a fault by retrieving a prescribed pre- broadcast program and/or re-broadcast program and then trying preliminarily the recording of an extracted pre-broadcast program and/or a re-broadcast program in response to the trial recording of the reserved designated program. SOLUTION: When a pre-broadcast program, i.e., a program where the identifier of a program group is coincident with the identifier of a sequence is retrieved and extracted, the recording of this program is tried. When this recording is normally over and the broadcasting of a reserved designated program starts, the recording of the favorite reserved designated program is tried. Then it's decided whether the recording is possible in regard to a fact whether a pre-broadcast program is normally recorded. If this recording and the recording of the pre-broadcast program are normally over, a series of reserved recording processes are over. When a user instructs the reproduction of the reserved designated program, a normally recorded pre-broadcast program is reproduced in place of the favorite reserved designated program whose reserved recording is failed.

Title: Horizontal deflection circuit
Inventor: ISHIKAWA KATSUMI
IPC: H04N3/16
Filed: 1984-04-12
Abstract: PURPOSE:To obtain the same deflection power as a conventional TV receiver scanning state by changing a value applied to a horizontal deflection yoke depending on the scanning frequency and double-speed scanning frequency of a conventional TV receiver. CONSTITUTION:When a conventional TV receiver is driven by a scanning frequency fH, a switch 12 is thrown to the position (a) and the same deflection as the conventional method is applied. Then the switch 12 is thrown to the position (b) for the double speed scanning and a double speed scanning frequency 2fH is inputted to a base of a transistor 3. Thus, the scanning period is halved. Since coils 14, 15 are connected in parallel in this case, the inductance of the yoke 13 is decreased to 1/4. Thus, the deflection power at the doublespeed scanning is the same as that at the conventional TV receiver scanning. Then it is not required to replace the resonance capacitor.

Abstract: PURPOSE: To relieve the load on a central processor by providing a communication controller, which detects and counts illegal frames generated due to the characteristic deterioration a of transmisstion line, to a circuit terminal.  
     CONSTITUTION: Circuit control part LCT of communication controller CCE provided to the circuit terminal detects F patterns (synchronous pattern)and supplies data, information between F patterns, to byte control part BTC, byte by byte. On counting the frame length, BTC discriminates whether data has the prescribed length; if its length is shorter, the frame is annulled and the number of frames annulled is counted by a counter (illegal frame counter) incorporated while normal frames are transferred to central processor CPU by way of channel CH. The above- mentioned count value is transferred to CPU together with the command conclusion at the time when the reception of frames of more than byte length ends.
