Abstract: PROBLEM TO BE SOLVED: To provide an electronic balast circuit which has a power factor correction circuit, enables soft switching, has a high power factor, has a relatively simple construction, and can be manufactured at a relatively low cost. SOLUTION: An input circuit 51 by which the power factor correction and the filtering are applied to an AC input voltage and a rectified voltage is obtained, and an inverter circuit by which the rectified voltage is switched and an AC signal is applied to a resonance load circuit, are provided. In the input circuit, a resonance tank circuit which practices soft switching of the switch of the inverter circuit is provided, and inductors are provided on the AC side of a diode bridge rectifier. If the components of a power factor correction circuit are arranged as described above, the bridge rectifier can exhibit both a rectification function and a current blocking function, so that the number of components of a ballast circuit can be reduced. With this constitution, a highly reliable electronic ballast circuit can be obtained at a low cost.  On the other hand, the switching frequency and the switching duty cycle are controlled independently of each other and the switching frequency of the switch is controlled so as to adjust an input current, and the switching duty is controlled so as to adjust the output voltage.

Title: Digital acoustic data output device
Inventor: ITO NAOAKI
IPC: G10L19/00
Filed: 1994-12-29
Abstract: PURPOSE: To reduce the waveform distortion in the technique where offset data is added to original digital acoustic data at oversampling intervals and lower bits are omitted thereafter to generate the output data and this data is outputted to a D/A converter. CONSTITUTION: An adder 102 generates the N-fold oversampled X-bit addition value having the value, which is increased/reduced by 1/N value  2<(x-> BIT<)> /N} of the value obtained by expressing the width of one quantization step of BIT- bit data for D/A conversion by the precision of original X-bit input data, in accordance with the inclination of increase/reduction of X-bit input data with respect to this X-bit input data from an input register 101 which is changed at sampling intervals synchronized with the sampling frequency. A quantization register 104 converts the X-bit addition value as parallel data to serial data while omitting lower (X-BIT) bits and outputs this serial data to the D/A converter where the number of conversion bits is BIT and conversion is performed synchronously with the oversampling frequency.

Title: Tool suitable for adhesive forming of joint for closed conduit water drain unglazed clay pipe and its adhesive forming method
Inventor: MATSUMAE TSUKASA
IPC: F16L9/10
Filed: 1993-12-07
Abstract: PURPOSE:To facilitate production by connecting a formed, dried, and baked main clay pipe integrally to a branch clay pipe with adhesive agent. CONSTITUTION:After a form has been installed on a cylindrical clay body for main and branch pipes, it is cut with a piano wire along a specified line of it to form connecting parts. Next they are dried and baked to form main and branch clay pipes 4A2 and 5A2. Also the connecting round hole 4A21 of the pipe 4A2 is stuck to the slant edge 5A21 of the pipe 5A2 with adhesive agent such as silicone sealant of one-liquid type. In this case, because the pipes 4A2 and 5A2 are all unglazed pipes, gel adhesive agent permeates them to form not only the adhesive effect of a connecting face but also a permeating layer. In addition, because the permeating layer provides high water proofing property, separation of the adhered part due to permeation of water can be prevented. Thus a conventional production capability can be maintained, joints can be made without requiring skilfullness, parts can be replaced partially if any fault occurs, and cost can be reduced.

IPC: B41J2/135
Filed: 1992-11-27
Abstract: PURPOSE: To eliminate the need for the contour writing of etching masks by removing a second layer of a second anti-etching material, without damaging a first layer of a first anti-etching material. CONSTITUTION: After a pattern of vias 20 is formed on a silicon nitride layer 18, a wafer 10 is anisotropically etched with KOH to form recessed 22. In this example, these are ink pots 30 used as ink-injecting holes. After removing the silicon nitride layer 18, the wafer is cleaned and etched, depending on the orientation, using a patterned oxide layer 12 as an anti-etching mask. Thus small and minute channel recesses 24 are etched with a high dimensional accuracy. This enables two successive anisotropically etching steps, without need for the contour writing of etching masks.

Abstract: PURPOSE: To improve the performance of a compressor by forming a crescent cutoff portion at the side of a driving pin of a driving shaft coupled with an eccentric bushing under an orbiting scroll, and a crescent plane portion at the side of an eccentric hole of the eccentric bushing. CONSTITUTION: An eccentric hole 23' of an eccentric bushing 23 and a driving pin 22 are crescent-shaped by removing a side part from them. Reactionary force and centrifugal force of an orbiting scroll act upon the center of the eccentric bushing 23 coupled with the back of the orbiting scroll to rotate the eccentric bushing 23 eccentrically with the driving pin 22 as the center.  When the eccentric bushing 23 is rotated left-wise across a θ with respect to the driving pin 22 in the shape of the driving pin 22 and the eccentric hole 23' of the eccentric bushing 23 coupled the driving pin 22 under such a condition, the orbiting radius which is the distance between the center O1 of a driving shaft 21 and the center O3 of the eccentric bushing 23 changes from ε to ε', however the rotation of the eccentric bushing 23 is limited such that the value thereof is smaller than a predetermined minimum reference value. The orbiting radius is limited within a predetermined maximum reference value in right-wise rotation.
