Granted: 1988-06-22
Abstract: The wheeled hospital bed is removably connectible to a drive unit. The bed comprises articulated frame sections, a driven shaft, a linkage interconnecting the driven shafts and the frame sections for articulating the latter in response to rotation of the driven shafts, and a first guide structure.  The drive unit includes motors and drive shafts.  A second guide structure is arranged to interact with the first guide structure of the bed when the bed is merged with the drive unit to orient the bed and drive units such that the drive and driven shafts are mutually aligned.  The drive and driven shafts include a self-coupling mechanism for establishing a drive connection when in a merged condition.

Title: Printing mechanism
Inventor: SHIMOJO TETSUJI
IPC: B41J2/28
Filed: 1985-02-02
Granted: 1989-10-12
Abstract: Magnetic members, so-called armatures (1), are attracted by a permanent magnet (3) while deflecting resilient members (9,10) are connected to one end.  The members are associated with corresponding electromagnets which are energised selectively to release the associated magnetic members by cancelling the magnetic attracting force of the permanent magnet, so that the magnetic member is actuated by the energy stored in the corresponding resilient members to drive the printing element.  One end of the magnetic member contacts a yoke (I) mounted on the magnet so as to form a fulcrum for the rotation of the member.

Title: Semiconductor device
Inventor: MARIAPELGROM MARCELLINUS J
IPC: G11C27/04
Filed: 1987-04-06
Granted: 1995-05-15
Abstract: The invention relates to a CCD having a so-called diode cut-off input, in which the input diode is applied to a reference voltage and the input signal is supplied to the input gate located in front of the first clock electrode. More particularly if the electrodes are composed of a transfer part and a storage part with incorporated potential difference, it is possible that, when charge is transported from the input gate to the first clock electrode, a large amount of charge is left behind. In order to avoid this and/or to be able to enlarge the dynamic range of the input signal, a MOST switch controlled by the same clock voltage as the first clock electrode is arranged between the input gate and a reference voltage, for example earth. This switch becomes conducting when the charge is transferred, as a result of which the potential level below the input gate can be adjusted above the surface potential below the transfer part of the first clock electrode.

Abstract: The preparation for emulsion fuel (I) with waste oils consists of (1) adjusting mannitan monostearate and polyoxyethylene condensate 2:1 to HLB 3-4, (2) mixing (1) with water 1000-2000 volume at 70-80 deg.C, (3) adding 0.01% polyvinylalcohol to (2) to get surfactant solution (II), (4) emulsifying de-mineralized oil such as cutting machine oil or lubricant and Bunker-C oil with (II) in the ratio of 60:20:20 at 75±5 deg.C for 30 sec to 5 min at 3400-3800 rpm in specially designed reactor (III) to get (I). Inside of hexagonal cylinder of (III), 3 baffles (10) on the wall, 3 poles (11) on the top, 2 rotating bars settled from the bottom give stable emulsion for (I) at 120' reaction angles.

Title: Lead frame
Inventor: LEE KUK-SANG
IPC: H01L23/495
Filed: 1991-11-19
Granted: 1994-08-16
Abstract: The lead frame includes ground electrodes (23,24) between each lead (23,33) to absorb the electric signal flowing in each lead so that the mutual interference between neighbor leads are prevented. And it also reduces the noise voltage caused by the inductance of the leads itself because the ground electrodes absorbs the noise voltage. It also increases the heat radiation ratio of the package because the surface of pads (21,31) is expanded by the ground electrodes.

Title: Electrode for nitrate laser
Inventor: KIM DAL-U
IPC: H01S3/038
Filed: 1991-12-07
Granted: 1994-08-20
Abstract: The uneven discharge in an electrode of a nitrogen laser resonator is eliminated by using the electrode. The positive electrode is made by cutting a rod having a large curvature on its end and the negative electrode is made by forming a groove in its center. The groove in the negative electrode is filled with dielectric material and is covered by a mesh.
