Title: Driver and driving method for piezoelectric transformer
Inventor: KAMIYA KENJI
IPC: H01L41/107
Filed: 1999-09-10
Abstract: PROBLEM TO BE SOLVED: To obtain a driver and a driving method for piezoelectric transformer, in which a piezoelectric transformer can be driven with a maximum conversion efficiency or can supply a relatively high output voltage, regardless of variation in the input voltage level, load or temperature. SOLUTION: Frequency of an AC drive signal is modulated by an AC modulation signal V3 of frequency fs, using an AC modulation signal V1 of frequency fc and inputted to the primary side of a piezoelectric transformer 10. The phase difference between a component of frequency fs in the voltage and a component of frequency fs in the current of an AC signal V7 inputted to the primary side of the piezoelectric transformer 10 is detected as an AC signal V16. The AC signal V16 is then multiplied by an AC modulation signal V3 to produce an AC signal V17 and the level of DC component V2, which is kept at substantially 0 at all times by varying the frequency fc through a VCO 21.

IPC: G21F9/02
Filed: 1987-10-15
Abstract: PURPOSE:To capture and recover effectively liquid or solid fine particles of an alkali metal such as Na, K and its compounds from a fluid carrying them by using columns packed with particulate materials of metal and/or ceramic etc. CONSTITUTION:More than one columns 1A-1D packed with particulate materials being used, a fluid PF carrying liquid or solid particles of an alkali metal and its compounds is introduced through an inlet 4 of the column 1A, which is kept at a temperature below m.p. of the alkali metal to be captured, to have the fine particles captured on surfaces of the particulate materials. Next, a packed column, e.g., the column 1B, wherein the captured material reaches a maximum, is heated up sequentially to a temperature above m.p. of the alkali metal to have the liquid alkali metal LA discharged through an outlet 6. Then, a solution LF, such as water, which is able to dissolve the alkali metal compounds, is injected through an inlet 7 to the packed column 1C to take out remaining metal compounds. Finally, the packed column 1D is dried by introducing a drying fluid DF.

Title: Main spindle normal direction control method of numerically controlled machine tool
Inventor: OZAKI YASUO
IPC: G05B19/4103
Filed: 1994-10-24
Abstract: PURPOSE: To enable easy machining even if the tool edge of a numerically controlled machine tool is offset for the rotational center of a main spindle by controlling the rotational angle of the main spindle so that the tool edge may be always maintained in a right angle for the machining progress of a machining program locus. CONSTITUTION: For example, at the time of groove machining, a main processor 33 reads out a machining program from RAM 39 one block by one block and analizes. During the normal direction control of the main spindle, the calculation of respective offset vectors are carried out from front/rear two blocks following such case that a main spindle center goes through inside or outside, according to the state in their joints. An arc interpolation from a front block finish point to a next block start point is calculated. At the same time, the interpolation calculation for synchronizing the main spindle is carried out. Thus, the groove machining can be carried out without being conscious of it by the movement of the locus of the tool center and at the same time the synchronization of the main spindle by the tool center, even if the tool edge is offset for the main spindle center.

Filed: 1990-09-27
Abstract: PURPOSE:To reduce a load on a host processor by representing the common memory storing position of sound data in one message in two kinds of parameters of leading address and end address, preparing corresponding memory, and furthermore, preparing a reload request circuit for the host processor. CONSTITUTION:When the host processor 1 sends (m) pieces of sound data to a first trunk, the host processor judges that it is required to issue sound output first, and sets an initial value, and writes the leading address and the end address representing the storing position of common memory 8 on the first trunk allocation addresses of the trunks of first fundamental memory 4 and second fundamental memory 5 on a common memory control part as the parame ter of the sound data for the first time. When a reload request is issued by information from the reload request circuit 12, the number of the sound data is updated, and when it is judged that an update number shows an (m+1)th number, the same operation is performed on up to m-th sound data repeatedly, and the operation is stopped at (m+1)th data. In such a way, it is enough to make access the common memory control part by the host processor for (m) times, and also, it is possible to recognize access time to the common memory control part by the reload request, which reduces the load on the host processor.

Title: Valve timing control device for engine
Inventor: OGURA AKIRA
IPC: F02D29/00
Filed: 1999-09-14
Abstract: PROBLEM TO BE SOLVED: To prevent errorneous learning caused by a change of an external load to an engine when learning a reference position of a variable valve timing mechanism. SOLUTION: In this control device, in the case that an input signal of an air-conditioning switch is inverted, a most lag angle learning cancellation flag FLRCCL is set (S101, S102) to command cancellation of most lag angle learning. In the case that switching between a non-running range and a running range is executed, the most lag angle learning cancellation flag FLRCCL is set (S103, S102) to command the cancellation of the learning. When a lapsed time after the stop of the learning reaches a set time (S101-S105), the most lag angle learning cancellation flag FLRCCL is cleared (S107) to permit the most lag angle learning.  That is, in the case that an external load changes, the learning is temporarily cancelled to prevent the errorneous learning caused by a change of actual valve timing calculated from both a crank angle and a cam position, and to prevent degradation of controllability in valve timing control from occurring.

Title: Controller for engine
Inventor: FUJIWARA KUNIHIKO
IPC: F02B29/08
Filed: 1990-09-28
Abstract: PURPOSE:To increase the output torque by correcting the inertial harmonized revolution speed for opening a downstream side throttle valve when a valve timing varying mechanism is fixed to the low speed side, in the constitution where each throttle valve is installed on the upstream and downstream sides of the collection part of intake passages. CONSTITUTION:An engine 1 is equipped with throttle valves 45 and 49 arranged on the upstream side and downstream side of a collection part 40 in an intake passage 7 and a valve timing varying mechanism 11 for at least selecting the opening/closing timing of a suction valve to the low speed side and high speed side at a prescribed engine revolution speed, and when it is detected by a detecting means 54 that the valve timing varying mechanism 11 is set to the low speed side timing, the engine revolution speed with which the opening degree of a downstream side throttle valve 49 is increased is corrected to the low speed side inertial harmonized revolution speed by a correcting means 56 so that the inertial effect of intake is generated in a low speed side timing. Accordingly, the reduction of the output torque due to the deflection between the opening operation revolution speed and the inertial harmonized revolution speed of the downstream side throttle valve 49 is eliminated, and the output torque is increased.
