Title: Refrigeration unit
Inventor: HARA MASAKANE
IPC: F25B1/00
Filed: 1999-02-26
Abstract: PROBLEM TO BE SOLVED: To quickly stabilize the travel of an electronic expansion valve by making the control of the travel of the electronic expansion valve match the actual operating state with a simple method. SOLUTION: When the operating condition of a refrigeration cycle is in a superheating range while the current temperature Td of a delivery pipe is estimated to tend downward from the previous memory data, or the operating condition of the refrigeration cycle is in a moisture range while the current degree Δ T of delivery superheating is estimated to tend upward from the previous data, the travel of an electronic expansion valve 3 is held at that immediately before it is determined by a PID control based on the preceding operating condition in the refrigeration cycle, thereby eliminating excessive opening or closing of the electronic expansion valve 3.

Abstract: PURPOSE:To reduce the influence of power source noises even in two-frequency excitation with a large time constant by performing excitation with an exciting current which has two frequencies, i.e. a low frequency as one of the even component of a commercial frequency and a high frequency shifting slightly from an integral multiple of the commercial frequency, and detecting a generated signal voltage. CONSTITUTION:An exciting means establish a magnetic field which has 1st frequency and 2nd lower frequency. A 1st demodulating means discriminates the signal voltage generated corresponding to a flow rate by the excitation of the exciting means according to its 1st frequency and outputs the signal voltage, and a high-pass filter filters the output. A 2nd demodulating means discriminates the signal voltage according to the 2nd frequency and demodulates it, and a low-pass filter filters the output. An adding means puts the outputs of the high-pass filter and low-pass filter together by addition. Then the value of the 1st frequency is set to a frequency shifting slightly from an integral multiple of the commercial frequency and the value of the 2nd frequency is set to an even submultiple of the commercial frequency.

Abstract: PURPOSE:To make color strength and color sensitivity higher and to improve coloring properties and weather resistance by causing the title recording material to contain, as a sensitizer, p-octylphenoxybenzyl or/and di(p-octylphenoxy)butane together with coloring and developing materials. CONSTITUTION:A thermal coloring layer contains at least one sort selected from compounds expressed by formulae I and II.

These compounds can be used separately or by the combination of two sorts in an appropriate ratio and the usage of the compound is normally selected within the range of 50-300 pts.wt. per 100 pts.wt. of developer. When this quantity is less than 50 pts.wt., the effect of the compound cannot be displayed sufficiently and, when the quantity exceeds 300 pts.wt., the coloring temperature becomes too low for obtaining desirable results. As occasion demands, another sensitizer, e.g. a higher fatty acid or its ester can be used jointly.

Title: Method for adjusting frequency of surface wave device
Inventor: KADOTA MICHIO
IPC: H03H9/25
Filed: 1985-03-13
Abstract: PURPOSE:To adjust the frequency without increasing the propagation loss by forming a thin film of polyimide group resin on a surface wave substrate and changing the film thickness formed in this way. CONSTITUTION:The polyimide group resin forming the thin film is given on the surface wave substrate 1 by a simple device such as a spray gun 4. In using a proper mask 2 in this case, the frequency of the surface wave device is adjusted to a desired part only selectively and the thin film with uniform film thickness is formed. The thickness of the thin film is controlled by adjusting the time of spray. Since the frequency of the surface wave device depends on the film thickness, the frequency is adjusted by changing the film thickness. On the other hand, the thin film made of the polyimide group resin does not almost increase the propagation loss of the surface wave. Then the frequency is adjusted without much increasing the propagation loss.

IPC: H03F1/32
Filed: 1981-04-06
Abstract: PURPOSE: To obtain an audio amplifier which has an extremely low distortion factor by detecting the collector current of a driver transistor (TR) by an audio negative feedback amplifier, and then feeding it back to the base of a predriver TR positively.  
     CONSTITUTION: An audio signal inputted to an input terminal 1 drives a predriver TRQ1, which drives driver TRs Q2 and Q3. Output TRs Q4 and Q5 are driven by the TRs Q2 and Q3 to output an amplified signal to a load resistance Rl. The collector current of the TRQ2 is supplied through a current detection resistance R5, and paet of a detected current is fed back to the base of the TRQ1 positively through a feedback resistance R6. Thus, the TRQ4 decreases in (hfe) and the collector current of the TR1 is increased so that an increment in the base current of the TRQ2 is compensated. Therefore, even if the hFE of the TRQ4 decreases, a sufficient driving current is obtained and the distortion factor of an output is improved.
