Title: Capacitive proximity sensor
Inventor: KAWASHIMA KAZUNORI
IPC: G01B7/14
Filed: 1995-06-07
Abstract: A capacitive proximity sensor includes a pulse-generator 1 which supplies pulses to separate delay circuits 2, 3, circuit 3 including a reference capacitor 16 and circuit 2 including a electrode 7 acting as a detection capacitance. When the output of the pulse generator is high, respective current sources 9 and 11 charge the detection and reference capacitances with a constant current and when the pulse generator output is low, the capacitances are discharged through resistors 10, 14. The outputs of the delay circuits are passed via Schmitt trigger circuits 4, 5 to a phase discrimination circuit 6 which detects the respective switching times of the Schmitt triggers to detect the presence or absence of an object in proximity to the electrode. In another embodiment (figure 5, not shown), the capacitances are instead discharged at a constant rate by respective constant current circuits (52, 53). <IMAGE>

Title: Rotary shaving device
Inventor: FRANKLIN MICHAEL JOHN
IPC: B26B19/30
Filed: 1995-07-13
Abstract: A dry shaving device with a handle 11 comprises a straight, stationary bottom blade 7, which touches a surface 13 such as skin from which bristle or other hair-like material protrudes, against which a cylinder of spirally-mounted blades 6 rotates, so that these blades have a shearing action on the bristles. This is effected by the action of pulling handle 11 parallel to the surface with blade 7 and wheels 1 touching the surface, causing wheels 1 to rotate and drive belt 3 via pulley assembly 2, 20 and 22, thus turning cylindrical blades 6 on shaft 5. This action may be reversed by pushing the handle in the opposing direction so that blade 7 is rotated to a new position where it is acted upon by blades 6 in the same manner as before but in the opposite direction. The device is designed to be hand-operated, but power such as an electric motor could be applied as necessary, to drive shaft 5. <IMAGE>

Title: Production of filled unit food portions
Inventor: PARKER STEPHEN FAVOR
IPC: A23L13/50
Filed: 1994-08-12
Abstract: A method and apparatus for introducing an edible filling into a unit food portion such as a chicken breast fillet. A mould set (1) is described which operates with a sharpened probe (4) for making an aperture in the food portion and an injector for introducing the filling into the aperture. The mould parts involve use of two lids (3, 6). a first of which contains the food during formation of the aperture and the second of which allows for the increased volume due to the filling, and has a hinged section (7) which allows for a further increase in volume due to presence of the injector which increased volume is reduced as the injector is withdrawn.

Title: Apparatus and method for determining geostrophic wind velocity
Inventor: WIESE CHUCK F
IPC: G01P5/14
Filed: 1994-08-22
Abstract: A geostrophic winds forecasting method (10) determines an atmospheric density (D) (14) and a Coriolis parameter (F) (16) at a given location. The atmospheric pressure is detected N times (20) at the location over a predetermined period of time (t). The period of time (t), e.g., two hours, corresponds to the time required for a pressure surface to travel a distance (x) at an empirically determined velocity, e.g., 35 knots. The change in pressure ( DELTA P) is detected over a period of time (t). The geostrophic wind velocity (VG) is then determined (22), according to the invention, based on the following relationship: VG = [1/(D x F)] x ( DELTA P/X]. The resulting geostrophic wind velocity (VG) is then displayed (25). At 35 knots, over a given two hour period, the distance X traveled by the pressure surface is approximately equal to 129,640 meters. The method is embodied in a weather instrument comprising a conventional barometer to produce a weather forecasting station. <IMAGE>

Title: Mobile radio re-synchronizing procedure; communication handover
Inventor: OHMORI TADASHI
IPC: H04W56/00
Filed: 1996-09-27
Abstract: A mobile radio (B, Figs.1A,1B) in communication with a first base station (A1) on a TDMA/TDD traffic channel performs a re-synchronizing subroutine in response to detecting that the level of the signal from the base station is below a first reference or the bit error rate is above a second reference. In a first part of the subroutine, the mobile tunes to the control channel of an adjacent second base station (A2) and performs a synchronizing operation with that station in response to receiving control data therefrom, whereby communication handover to the adjacent base station is effected. If the mobile does not receive control data from the adjacent base station within a predetermined interval, it performs a second part of the subroutine by monitoring for a sync burst signal transmitted from the first base station (A1) when it cannot receive the signal from the mobile during the communication on the traffic channel. If the mobile receives the sync burst, it transmits a sync burst to the first base for re-establishing the communication through the first base. If the mobile fails to receive the sync burst during a predetermined interval, the subroutine returns to the first part, the first and second parts being alternatingly repeated until the mobile establishes communication through the second base or re-establishes communication through the first base. In an alternative subroutine, the mobile first attempts to re-synchronize to the first base station and then attempts to synchronize to the second base station.

IPC: F02D41/00
Filed: 1997-06-03
Abstract: At least engine speed, opening of an accelerator and amount of intake air are detected as an engine operating condition. A basic volume of fuel to be injected is calculated on the basis of at least the engine speed and the opening of the accelerator. A target injection timing of fuel is set on the basis of the engine speed and the basic volume for injecting fuel oil. An actual fuel injection timing is detected. A basic target EGR rate is calculated on the basis of the engine speed, the amount of the intake air, and the basic volume for injecting fuel oil. Adjustment of the basic target EGR rate is calculated on the basis of the basic volume for injecting fuel oil, the target fuel injection timing, and the actual fuel injection timing. As an alternative to injection timing in the calculations, a maximum volume for injected fuel oil is calculated and compared with the basic volume.

Title: Coaxial connecting means
Inventor: HAERRI ROGER
IPC: H01R13/646
Filed: 1997-12-03
Abstract: The housing bore (5) is substantially widened in the shape of a step at its edge and the outside diameter (A) of the support plate is widened correspondingly. The contact surface (8) of the housing (2) is reduced in accordance with the step-shaped widened part (7) to form comparatively narrow annular surfaces. An advantage of this is that passive intermodulation can essentially be prevented by the reduction of the contact surface, creating a subsequent increase in contact pressure.
