Title: Temperature responsive controller for cardiac pacer
IPC: A61N1/365
Filed: 1987-04-27
Abstract: A controller for variably controlling the pacing rate of a cardiac pacer responsive to temperature which includes a logic and control unit, a parameter communication unit, an analog to digital converter and a temperature sensor. The temperature sensor in the right ventricle or atrium communicates a value related to blood temperature through the analog to digital converter to the logic and control unit. The logic and control unit operates under control of the rate algorithm to calculate a pacing rate value related to variations in the blood temperature. The pacing rate value is calculated as the sum of a reference rate, a natural rate response term, and a dynamic race response term which contributes rate only in response to physical activity. A step rate response is also added to the calculated pacing rate when predetermined criteria related to the blood temperature and calculated pacing rate indicate the onset of physical activity. Under the control of the rate algorithm, the controller also maintains the level and rate of change of the calculated pacing rate within predetermined limits, and prevents the pacing rate from remaining at the maximum rate limit after physical activity has ceased.

Title: Refractometric detector for liquid chromatography
IPC: G01N30/74
Filed: 1987-03-24
Abstract: Chromatograph in high performance liquid phase comprising a monochromatic light source emitting a beam which, after splitting, is divided into two parallel beams which go respectively through two cuvettes, the one containing a reference liquid, the other the measurement liquid. The two beams on coming from the cuvettes go into a detection unit. After splitting, each of beams R, M is divided into a system P with a semireflecting surface SR, a part going into one of the cuvettes CR, CM and being reflected by the rear of the cuvette forming a mirror MC to come back to semireflecting surface SR along a reverse path, the other part of the beam coming to be reflected on a mirror MR, at right angles to each beam, moved by a piezoelectric device PZ. The two parts of each beam coming from cuvettes CR, CM and coming from mirror MR moved by a piezoelectric device are joined in semireflecting system P, SR to reach a photodiode DM, DR sending the emitted signals to a phasemeter measuring the phase shift and the number of cycles k of phase shift between beams. The signals emitted by photodiode SM of the measurement beam are sent to a generator G exciting the piezoelectric system PZ, source S being a laser source.

Title: Self-closing valve for sanitary installations
IPC: E03D3/04
Filed: 1987-10-12
Abstract: A self-closing valve assembly for sanitary installations is disclosed. The valve assembly includes upper and lower valve housings which define a metering chamber that is normally filled with a metering fluid. A metering means, shiftably mounted in the lower valve housing, includes a first one-way valve means which displaces a predetermined volume of the metering fluid when said valve assembly is shifted to its opened position. A closure means, which includes a second one-way valve means, is operably coupled to the metering means to automatically shift said metering means from its opened to its normally closed position, by transferring the displaced volume of said metering fluid in the metering chamber through a second one-way valve means after a predetermined period of time has elapsed, to thereby close said valve assembly.
Patent EP-0280254-A3 (EP)
IPC: H04N5/10
Filed: 1988-02-23
Abstract: A digital timing generator using a state machine 
detects the presence of a predetermined pulse pattern 
at the input to generate a valid pulse output, and 
from the periodic repetition of the valid pulse output 
indicates the presence or absence of an input signal 
having the predetermined pulse pattern. The edges of 
the pulses at the input are detected (10) and the pulse 
widths are determined by a time duration counter (14) as 
being within the limits corresponding to the 
predetermined pulse pattern. A valid pulse counter (16) is 
incremented for each pulse having the proper pulse 
width, and when the count of the counter reaches a 
predetermined value a valid pulse output is 
indicated. The valid pulse output may be delayed 
before being input to a signal presence detector. 
Each valid pulse output restarts a time interval 
counter (24) and increments a valid input counter (26) so long 
as the time interval timer does not reach a maximum 
time interval. When a predetermined minimum value of 
the valid input counter (26) is reached, a valid input 
signal is indicated. Then the valid input counter (26) 
counts the number of consecutive times that the 
maximum time interval is reached without the receipt 
of the valid pulse output, indicating the absence of 
the input signal when a predetermined maximum value is 
reached.

Title: Method of forming a fine pattern
IPC: H01L21/3213
Filed: 1988-08-19
Abstract: A photoresist is coated on a substrate to form a 
planar surface, thus to form recessed portions 
corresponding to a mask of a pattern to be formed in the 
photoresist layer having planar surface. SiO₂ etc. are 
deposited into the recessed portions to prepare a mask, 
thus to form a fine pattern by anisotropic etching. As a 
result, by films remaining below the recessed portions 
formed in the photoresist layer having planar surface, a 
fine pattern is formed.

Abstract: The disclosure relates to a semiconductor wafer 
aligning device (30). A cassette (10) of conventional 
form is loaded with a plurality of semiconductor wafers 
(20) having indexing flats (21) of the known type and 
placed over three parallel rollers (31, 32, 33) 
rotatably secured to a frame (35). The three rollers 
include a center roller (31) and two side rollers (32,33) 
positioned only slightly higher than the center roller 
such that their rotary motions can be communicated to 
the wafers by contact, depending on the positions of 
the individual indexing flats. The indexing flats are 
roughly aligned in downward directions first by 
rotating only the center roller and after all three 
rollers are rotated to bring the indexing flats in 
upward directions, the wafers are more accurately 
aligned in a downward direction by rotating only the 
center roller and all three rollers are rotated 
thereafter for a predetermined period of time, 
depending on the desired angular position of the 
indexing flats.

coupled to a plurality of coin paths (21, 22, 23, 24), a 
coin separator comprises a discharge arrangement for 
discharging an erroneous coin from a particular one (21) 
of the coin paths to another coin path (42). As a

erroneous coin is supplied to the particular coin path. 
The coin separator may be constituted so that the 
particular coin path is closed by the selecting part 
after the erroneous coin is detected in a storing part 
(46) which is coupled to the particular coin path.
