Abstract: In a vane pump, a pump housing assembly contains a cam ring (25) having an internal cam surface (25A). A rotor carrying plural vanes is disposed within the cam ring and rotated by a drive shaft. Both end surfaces of the cam ring contact with a pair of flat contact surfaces formed within the pump housing assembly, respectively, and the vanes define plural pump sectors between the rotor and the cam ring, together with the rotor, the cam ring and the pair of contact surfaces. The contact surfaces are formed with a pair of intake ports (1F) and a pair of exhaust ports (1C). Furthermore, one of the contact surfaces is provided with a pair of pressure leaking grooves (50) formed at locations between the intake ports and the exhaust ports. The locations of the pressure leaking grooves are chosen so as to leak fluid in pump sectors communicating with the exhaust ports to adjacent pump sectors communicating with the intake ports through passages formed by the pressure leaking grooves and the side edges of vanes located between the two pump sectors whenever the instantaneous pressure of the fluid in the exhaust ports approaches an instantaneous maximum pressure. With this operation, the instantaneous maximum pressure is decreased, thereby the amplitude of the pressure pulsation being reduced.

Abstract: An electrically erasable programmable read-only memory is disclosed which has programmable memory cells (M) connected to parallel bit lines (BL) provided above a semiconductor substrate. The memory cells include NAND cell blocks each of which has a series array of memory cell transistors (M1 to M8). Parallel word lines are connected to the control gates of the memory cell transistors, respectively. In a data write mode, a selection transistor (Qs1) in a certain NAND cell block including a selected memory cell is rendered conductive to connect the certain cell block to a corresponding bit line associated therewith. Under such a condition, electrons are tunnel-injected into a floating gate of the selected memory cell transistor, and the threshold value of the certain transistor is increased to be a positive value. A logical data is thus written in the selected memory cell transistor. The data in the selected cell transistor is erased by discharging carriers accumulated in the floating gate thereof to its drain or the substrate, so that the threshold value of the certain transistor is decreased to be a negative value.

Abstract: A compact autonomous radio clock (11), especially in the form of a small travelling alarm or a wrist watch, is to be designed for the purpose, on the one hand, of ensuring a long operating life in conjunction with a battery of correspondingly compact dimensions and, on the other hand, of supplying a reliable time display even in the event of travels outside the reliable receiving area of a transmitter for coded time telegrams that is set up for a specific geographical time zone. For this purpose, the clock casing (20) is fitted with a multifunction switching device (21) and a decoder (23) assigned thereto, which evaluates the combination of the actual operation of push buttons (22). Thus, this switching device (21) can likewise be used at night to switch over the clock (11) into a power-saving storage state, and once again to switch it back into normal operation. Furthermore, the hours display can be varied by hourly steps in order to take account in the time display of a stay in the time zone adjacent to the transmitter. Beyond the adjacent time zone, that is to say in the case of manual change of the hours display by more than one hour, however, switching on of the receiver (12) is blocked, since the reception of useful time information (14) becomes increasingly unlikely there. Depending on the duration of the operation of a "transmitter call" button (22.2), either the receiver (12) is switched on with the time display switched off in order to supply up-to-date time information temporarily, although the information in the time memory (35) which has been transferred from the internal time-keeping circuit (16) is adopted for display when the receiver (12) does not supply any up-to-date time information (14) within a prescribed time interval; or else the time memory (35) is also reset and restarted from the time-keeping circuit (16). In the latter case, the clock (11) can also be taken into operation outside the reception area of a time-telegram transmitter, whereupon only the hours display is to be set up manually.

Abstract: The present invention is concerned with a receiver device for converting electrical signal from a headphone (4), a telephone receiver or the like into acoustic signals and outputting these acoustic signals. More particularly, it relates to a noise reducing receive device in which acoustic signals in the vicinity of an electro-acoustic transducer element (4) are converted by a microphone (6) into electrical signals and negatively fed back to an amplifier circuit (13) which is adapted for amplifying input electrical signals and supplying the amplified signals to the electro-acoustic transducer element (4). With the present noise reducing receiver device, the input electrical signals are amplified by the amplifier circuit (13) and converted by the electro-acoustic transducer element (4) into acoustic signals, which are output as output acoustic signals. A microphone (6) is arranged in the vicinity of the electro-acoustic transducer element and adapted for converting the output acoustic signals and external noises into electrical signals, which are negatively fed back to the amplifier circuit (13) via feedback circuit (7). The output acoustic signals may be heard at the desired noise reduction level by having the transfer function H of the electro-acoustic transducer element (4), the transfer function A of the amplifier circuit (13), the transfer function M of the microphone (6) and the transfer function β of the feedback circuit (7) presettable within the range of |AHMβ|» 1.

It is thereby possible to sense and measure all the worktools (7) of the most commonly encountered multi-spindle heads (8), using a single measuring beam (15). Even if two worktools (7) are situated in a common horizontal or vertical plane, one behind the other, each worktool (7) is sensed due to the oblique position of the measuring beam (15) to the x-y coordinate system.
