Title: Method and circuit for controlling temperature
Inventor: WATANABE KENZO
IPC: G05D23/24
Filed: 1985-08-30
Abstract: PURPOSE:To allow a simple circuit constitution to control a digital temperature by comparing the phase of a signal available from frequency-dividing a reference clock signal with that of a signal available from frequency-dividing a signal from a temperature/frequency converter so as to detect a difference signal between said two signals. CONSTITUTION:Where the oscillation frequency of a reference clock signal generator 1 and the frequency division ratio of a frequency divider 2 are fC and M, respectively, an input signal frequency to the input terminal 51 of a phase comparator 5 becomes fC/M. On the other hand, where the temperature of a temperature sensor and the sensitivity of the temperature/frequency converter 3 and the frequency division ratio of a frequency divider 4 are T deg.K, S and N, respectively, an input signal frequency to the input terminal 52 of the phase comparator 5 becomes ST/N. the phase comparator 5 outputs a voltage in proportion to the phase difference between said two signals. When the output voltage is negatively fed back to a temperature actuator so that the phase difference can be zero, the relationship fC/M=ST/N folds. Then M is set so as to attain fC=MS and a target temperature TS is set to N, whereby the temperature is controlled to become TS.

Filed: 1998-07-08
Abstract: PROBLEM TO BE SOLVED: To improve exhaust gas purification performance effectively using heat of exhaust gas by reducing heat capacity of a whole catalyst by decreasing total cross section of an exhaust gas flowing passage of an upstream catalyst as compared with a downstream catalyst, of the two catalysts arranged upstream and downstream of an exhaust passage. SOLUTION: In a catalyst device 2 connected with an exhaust pipe of an engine of an automobile, both catalysts 4, 5 respectively accommodated upstream and downstream of a catalyst container 3 are monolithic type, the diameter of the upstream catalyst 4 is shorter than that of the downstream catalyst 5 corresponding to the diameter of the catalyst container 3, and the length of the upstream catalyst 4 is shorter than that of the downstream catalyst 5. A clearance 6 of 5-50 mm is formed between the both catalysts 4, 5. Therefore, exhaust gas contact area per unit capacity for the upstream catalyst 4 becomes larger than that of the downstream catalyst 5, and mass per unit capacity is reduced, and therefore, the upstream catalyst 4 rapidly increases in temperature to provide activation, and this catalyst reaction heat can accomplish early activation of the downstream catalyst 5.

Abstract: PURPOSE:To achieve high saturated magnetic flux density and to contrive giving excellent magnetically soft characteristics with high permeability in a high frequency region by making the composition ratio of selected a specific quarternary system as component elements in a magnetically soft thin film within a specific composition region. CONSTITUTION:Adding of Al is effective for the improvement of the thermal stability and the magnetic characteristics of an Fe-Co-Si system alloy thin film and a composition of 5-15atom%, Si 10-17atom%, Al 8-13atom% and the remainder Fe is used. The composition ratio of each component element is required to be set within a required range and in the outside of the range, magnetically soft characteristics are deteriorated. A vacuum thin film formation technique is preferable as a method of making a magnetically soft thin film, and sputtering, ion plating, vacuum deposition, cluster ion beam method, etc., are available. Further, since the magnetically soft thin film prepared in this way has in itself high coercive force and its magnetically soft characteristics are not good, removal of the distortion of the film by heat treatment and improvement of the characteristics are preferable.

Title: Ink jet head
Inventor: FUJII MASAHIRO
IPC: B41J2/045
Filed: 1999-07-07
Abstract: PROBLEM TO BE SOLVED: To provide an electrostatic driven ink jet head in which high density can be realized while reducing the size. SOLUTION: The ink jet head is constructed by bonding a channel substrate 2 and an actuator substrate 3. The channel substrate 2 is provided with nozzles for forming ink channels, grooves for forming ink pressure chambers, grooves for forming orifices, and a groove for common ink chamber by anisotropic etching, and the actuator substrate 3 is provided with individual electrodes 15 and diaphragms 13 formed by sacrifice etching.
