Patent EP-0284047-A2 (EP)
Inventor: MATSUMOTO NAOAKI PAT DEPT DEV
IPC: G10H3/18
Filed: 1988-03-23
Abstract: When picking of a string is performed, the vibration of the string is detected by string trigger switches (TSW) accurately and quickly. When a fret operation position is changed during generation of a musical tone from musical tone generating circuit (60) caused by the string picking, the pitch of the musical tone is changed according to outputs of fret switches (FSW) to the one corresponding to the new fret operation position without generating a new musical tone. When the same string is stroked successively, the succeeding musical tone is generated while keeping the reverbera­tion of the previous musical tone under the control of microcomputer (30). The musical tone once generated will be stopped from being generated upon elapse of a predetermined time from the beginning of the tone gen­eration, irrespective of the type of its timbre. When a change of a fret operation state is detected by switch status detection circuit (50) to change to an open-­string operation state after the string picking, the generation of the musical tone being generated from circuit (60) stops at that timing. When this change occurs, it is selectable whether the generation of the musical tone is to be stopped or its pitch is to be changed to the one corresponding to the open-string operation state. The generated musical tone can freely be stopped from being generated through a manual opera­tion.

Abstract: In a light assembly (10) in which a holder (18) in which a bulb (14) is fixed is replaceably mounted in a lamp housing (40) having a reflector (42) formed integrally therewith, the portion (52) near the apex of the reflective surface of the reflector is formed flat, so that the reflective surface of the reflector can be formed without taking in consideration the molding precision of the portion near the apex and that any of the lamp units under different standards are applied can be accomodated. Furthermore, since the light emitted from the filament and going toward the flat portion can be prevented by a shade (60) from being incident upon the flat portion, thus preventing any glaring light from occurring.

Abstract: In the previously known methods for exchanging fixedly installed bathtubs, the bathtub body to be newly inserted was trimmed in the region of the bathtub edge despite the enamelling already provided. By this means, the enamel is damaged and the balance of the bathtub is destroyed. It is proposed, if appropriate, to bend a steel plate blank of the bathtub in its edge region and to bend it back in adaptation to the local installation conditions, then to enamel the bathtub and subsequently to insert the bathtub, which has been completely enamelled all around, into the remaining panelling.

Abstract: An inflating device for tyres on vehicles, particularly bicycles, has a valve coupled to an air pump which possesses a pump housing connected to the rim and a pump piston guided displaceably therein. The latter runs on a fixed guide path which results in a spacing changing in the radial direction, the pump piston being spring-loaded in the direction of the guide path. The air pump has a movably mounted control element for deactivating the air pump when a specific air pressure in the tyre is reached, this control element being subjected to the tyre air pressure counter to the effect of a spring.   So that the device is small, light and space-saving, the pump piston (10) and the pump housing (9) have catch means (23, 24; 30, 31) for mutual engagement in an inwardly pressed dead-centre position of the pump piston (10), and the control element (17, 19) is so designed and is so assigned to the catch means (23, 24; 30, 31) that an engagement of the catch means (23, 24; 30, 31) is blocked below the specific air pressure. <IMAGE>

IPC: H02M7/48

Abstract: A converter has an invertor arrangement which is furnished with power semiconductor components. In the event of high voltages in the DC intermediate circuit, the rated voltage and the rated insulation voltage of the power semiconductor components in the invertor arrangement must be taken into account. Conventionally, the invertor arrangement was furnished with power semiconductor components whose rated voltage and rated insulation voltage exceeded the voltage in the DC intermediate circuit. In order to be able to use semiconductor components with lower rated voltages and rated insulation voltages, that is to say, in particular, cheaper components, the invention proposes connecting a plurality of invertors in series, that is to say in cascade, so that only a proportion of the overall DC voltage is applied to each partial intermediate circuit produced in this way, so that the power semiconductor components in each invertor can be components with a low rated voltage and rated insulation voltage. The invertors are regulated by a regulator device such that the voltage breakdown is equal within the invertor cascade. Controlled resistor arrangements are provided on the individual invertors or the invertors which are connected in groups, to protect against the voltage surges which occur briefly in the event of disturbances in the system. <IMAGE>

Abstract: Method and apparatus for non-linearly filtering impulse and low frequency noise received over a network so as to avoid false activation of equipment is disclosed. A squelch circuit assures that only multiple transitions of at least three half-cycles in the received waveform of a proper frequency and amplitude will activate the receive while a single half-cycle, although of a proper frequency and exceeding the threshold, will not falsely activate the receiver. RC circuits provide a variable delay in the squelch portion of the filter to suppress impulses. In an alternative embodiment, double half-cycles will not falsely activate the receiver. Emitter-coupled logic (ECL) circuitry is preferably employed to provide speed adequate for ten-million bit per second transmissions.

The hot melt film is bonded to the resin sheet. In producing the optical fiber-connecting reinforcing member the resin sheet (1) is first placed on a lower holding plate with a guide, and a perforated plate is placed on the upper surface of the resin sheet. The perforated plate has longitudinal through holes bored therethrough at a specific interval. Hot melt films (4) and reinforcing ceramic base plates (3) are each preliminarily cut to a given size, and inserted into the longitudinal holes. An upper holding plate is placed on the perforated plate, and then hot pressing is effected.

Abstract: A noncontrolling type valve for use in a gaslighter, a port­able cooking stove and other burners, which valve comprises a valve body push-fitted in a recess formed in the top plate of a gas container; and a filter positioned under the valve body to permit the gas to flow at a controlled rate. The valve according to the present invention uses a porous concave object as a fil­ter. The filter is laid on an impermeable, resilient membrane. The gas invades the concave space of the porous object from the outside to flow in the valve opening. The rise of the surround­ing temperature will cause the membrane to bend yieldingly up­wards to cover the inside of the porous object, thereby prevent­ing the increase of the gas flow passing through the porous ob­ject over a predetermined flow rate.

Abstract: Apparatus and method for projection ion beam lithography are described which allow formation of low distortion, large field, reduced images of a mask pattern at a wafer plane using an optical column of practical size. The column shown is comprised of an accelerating Einzel lens followed by a gap lens, with numerous cooperating features. By coordinated selection of the parameters of the optical column, lens distortion and chromatic blurring are simultaneously minimized. Real time measurement of the position of the image field with respect to the existing pattern on the wafer is employed before and during the time of exposure of the new field and means are provided to match the new field to the existing pattern even when the latter has been distorted by processing. A metrology system enables convenient calibration and adjustment of the apparatus.
