Abstract: PURPOSE: To enable the good display in which the pretilt angle of liquid crystal molecules is nearly close to 0° and reverse tilt does not occur at the voltage application to be obtained by forming orientation-treating films through vapor deposition of two stages in which angles of vapor depositions are respectively specified.  
     CONSTITUTION: Substrates 83 are supported to a rotator 82 which rotates about a revolving shaft 81. Vapor flows 86 produced by a vapor source 84 are defined of the angle of vapor deposition within a fixed range by the holes 88, 89 of a mask member 87. In this way, the first vapor deposition in which the main angle of vapor deposition is set in the angle range of 75W30° and the second vapor deposition in which the main angle of vapor deposition is set at angles below 30° are accomplished. In addition, shutters 85a, 85b are provided to the holes 88, 89. If only one of the shutters is opened at the vapor deposition of the first layer of the orientation treatment layer and only the other shutter is opened at the vapor deposition of the second layer, then this method becomes suited for volume production as well.

Title: Hysteresis comparator
Inventor: TANAKA SHINJI
IPC: H03K5/08
Filed: 1985-05-17
Abstract: PURPOSE:To set optionally the temperature coefficient of hysteresis width by switching a current source current of each emitter so as to change the potential difference of the resistor between both emitter terminals of a transistor (TR) pair constituting a differential amplifier. CONSTITUTION:In a hysteresis comparator, when differential input voltages V1, V2 have a relation of V1>V2, TRs Q13, Q14, Q15 are turned off and a current source Iphi3 is set. When the voltage V1 is small and collector currents (Ic) of TRs Q11, Q12 are nearly equal, the circuit is inverted and the current is nearly equal to (Iphi1+Iphi2+Iphi3)/2. A current of (Iphi1+Iphi3-Iphi2)/2 flows to a resistor R1 and an offset by said current is given. When the voltage V1 is large and the output is switched conversely, an offset of (Iphi1-Iphi2)/2.R1 is given. The potential difference of the offset gives a hysteresis width. In this case, since the current source Iphi3 is decided by a voltage drop of the resistor R1, the temperature coefficient of the hysteresis width is set optionally.

Title: Recording and reproducing system for magnetic disc
Inventor: OGAWA KOUICHI
IPC: G11B5/012
Filed: 1978-08-29
Abstract: PURPOSE:To possibly increase the recording density, by recording the video and audio information on the track at inner circumference and the digital information at the track at outer circumference, among a plurality of tracks of the magnetic disc. CONSTITUTION:The video information of low resolution is recorded and reproduced on the track group of innermost side with the multi-head block 10, and the video information required for high resolution is recorded and repreduced at the just next outer track group to the said track group to the multi-head 11. Further, the digital information is recorded and reproduced at the track group of external section with the multi-blocks 20 and 21. Thus, without matching the recording density of digital information to the inner circumferential track, it is matched to the external circumferential track excellent in performance. Then, higher recording density can be obtained than the recording density giving unnecessary margin to the outer circumferential track as conventionally. On the other hand, in the recording of video information, as far as especially greater resolution is not required, the deterioration of video quality is not a practical problem even if it is recorded on the inner circumference of disc.

Title: Integrated circuit for communication control
Inventor: INOUE SATOSHI
IPC: H04L69/40
Filed: 1996-04-25
Abstract: PROBLEM TO BE SOLVED: To make investigation of fault cause efficient without using a monitor measurement device on the occurrence of a line fault by storing tentatively user information to a transmission reception data buffer area and storing frame history data and an error detection result for each transmission and reception. SOLUTION: A communication control integrated circuit 1 stores tentatively user information sent/received to transmission reception data buffer areas 21, 22 of an external memory 2. Simultaneously, frame history data corresponding to in-frame data other than user information are stored tentatively for each frame transmission reception to a history data buffer area 23 via a history data transfer means 12. Moreover, an error detection means 13 detects an error in an address of in-frame data, control data and an FCS(frame checking sequence) and stores each detection result to the history data buffer area 23 via the transfer means 12. Thus, on the occurrence of a line fault, the investigation of the cause to a line is made efficient without the use of a line monitor measurement device.
