Title: Disk valve
Inventor: SCHILS P
IPC: F16K1/22
Filed: 1978-03-16
Granted: 1982-05-31
Abstract: The disc-type valve assembly has a tubular body (10) and a disc-like valve plate (12) in the flow passage. A shaft is connected to the valve plate by a pre-stressed self connecting joint.

Title: Vehicle suspension system having toe direction control means
Inventor: KONDO TOSHIRO
IPC: B60G7/00
Filed: 1987-04-25
Granted: 1990-07-18
Abstract: Each wheel hub (6R) is connected to the body (1) of the vehicle by two transverse links. One link (4L) is ahead of the wheel and one link (5L) behind the wheel, which are constrained to swing vertically. The connection points between links and hub (12L, 14L) and links and body (8R,10R) are formed by resilient bushes. The bushes and links in combination are devised so that, for small inward transverse forces imparted by the road to the wheel the toe-in angle of the wheel changes at a given rate with force. As the transverse force increases the toe change rate decreases until at an even larger transverse force the toe-in rate increases once more.

Title: Magneto optical recording medium & method for manufacturing
Inventor: YASUAKI MORIMOTO
IPC: G11B13/04
Filed: 1988-09-30
Granted: 1996-12-04
Abstract: Optical-recording medium having a light-transmitting substrate layer. 
<??>CDs are such recording media, on which data are stored in so-called pits, that is to say depressions in a light-reflecting layer following the light-transmitting layer. In the case of magneto-optical discs, data are stored in a magneto-optical layer by magnetising in the one or the other direction of magnetisation. For reading the data stored in this way, use is made of the Kerr effect, which produces a measurable rotation of the polarisation plane when a linearly polarised light beam is reflected at the magneto-optical layer. Although both recording media - CD and magneto-optical disc - already have a high storage capacity, a considerable increase in the storage capacity is of great benefit, in particular for computer applications and as a video disc. 
<??>In order to increase the storage capacity considerably, the light-transmitting substrate layer (1) is followed by a light-reflecting magneto-optical layer (2), in which data can be stored on the one hand by magnetising and on the other hand by means of depressions (3), so-called pits. The light-transmitting substrate layer (1) may also be followed by a partially transmitting magneto-optical layer (2) without pits (3), which is then followed by a light-transmitting layer (10). In this or a following layer (11), data can be stored by means of pits (3). 
<??>Storage medium for computers, video disc, CD.

Abstract: 본 발명은 차륜 트레드를 압착하기 위한 브레이크 슈(300)와, 이 브레이크슈 (300)를 차륜 트레드로 이동 접촉시켜서 엑츄에이터에 의해 발동되는 제동력을 브레이크 슈(300)로 전달해주는 출력부재를 보유하는 제동 액츄에이터(100)와, 유니트의 해제상태에서 브레이크 슈(300)와 차륜 트레드 사이의 간격을 충분히 일정하게 유지시켜 주는 이완조절기(200)에 의한 단일구조로 구성되며, 상기한 이완조절기(200)는 각각 액츄에이터(100)에 의한 단일구조로 구성되며, 상기한 이완조절기(200)는 각각 액츄에이터(100)의 출력부재(19)상에 회전 가능하게 나사 맞춤 되는 1쌍의 나사너트(20)(21)를 보유하고, 여기서 액츄에이터(100)는 그 내부 실린더(2)(3)의 내측벽(6)(7)에 부합되어 회전이 불가능하고 단지 슬라이드만 할 수 있는 외주형상이 비원형으로 된 피스톤(4)((5)과, 튜브형으로 되어 피스톤 (4)(5)의 중앙에 부착된 피스톤로드(8)를 포함하고, 그리고 이완조절기(200)는 고정수단(22,24/25,26,27,28)을 포함하고 있어서 이러한 고정수단에 의해 양 나사너트(20)(21)중의 한쪽 너트 (20)를 튜브상 피스톤로드(8)에 대해 비회전적이고 해제 가능하게 억제하여 나사너트(20)가 출력부재(19)에 대하여 회전 할 수 없게 한 것을 특징으로 하는 트레드 브레이크 유니트에 관한 것이다.

Title: Optical information recording medium
Inventor: HAMADA EMIKO
IPC: G11B7/24
Filed: 1989-07-22
Granted: 1995-06-07
Abstract: An optical information recording medium comprising a light transmitting substrate, a light absorptive layer overlaying the substrate to absorb a laser beam and a light reflective layer overlaying the light absorptive layer, wherein an optical parameter represented by  rho  = nabsdabs/ lambda  where nabs is the real part of the complex refractive index of the light absorptive layer, dabs is the thickness of the light absorptive layer and  lambda  is the wavelength of a reading laser beam, is 0.05 </=  rho  </= 0.6, and the imaginary part kabs of the complex refractive index of the light absorptive layer is at most 0.3.
