Title: Atomization introduction device of sample liquid
Inventor: MORIOKA AKIHIRO
IPC: G01N27/62
Filed: 1998-05-18
Abstract: PROBLEM TO BE SOLVED: To prevent the formation of the waterdrop and the reatomization phenomenon of a sample liquid to be measured that has been atomized by forming the inner space surface of an end cap formed between a nebulizer and a spray chamber with an ultra water-repellent material. SOLUTION: For example, an ultra-water-repellent part 52a where the surface of fluororesin is roughened by the air blast method or the like is provided on the surface of an inner space 52A of an end cap 52 that is formed between a front end 50a of a nebulizer 50 and a rear end (an opening end 51a of an outer pipe 51B) of a spray chamber 51. As a result, even if a sample to be measured being atomized by the neblizer 50 hits against the surface of the inner space 52A and becomes a waterdrop, the growth is prevented, thus avoiding the reatomization of the waterdrop at the front end 50a of the neblizer 50 and hence preventing spike noise or the like from being generated and achieving an analysis stably and reliably.

Title: Solar heat collector pipe
Inventor: FUJINO MITSUHIRA
IPC: F24S10/70
Filed: 1978-12-11
Abstract: PURPOSE: To increase the heat collecting efficiency of a solar heat collector pipe by providing black portions on the inner light-receiving surface of a flow passage which is formed by combining transparent plates together.  
     CONSTITUTION: A transparent plate 7 and a lower cover 9 are combined together to form a flow passage. A black pigment is coated on the light-receiving surface of the lower cover 9 to form a black surface 8. Water 5 is introduced into the flow passage. Since the outer surface of the heat collector pipe is transparent, the heat absorption factor thereon is low so that the temperature of the outer surface of the pipe is lower than that of the water. Accordingly, heat loss on the outer surface of the heat collector pipe is low. Since the inner surface of the heat collector pipe is coated with a black pigment, the temperature of the surface increases owing to the high heat absorption factor thereof. This allows the heat collecting efficiency of the solar heat collector pipe to be improved.

Filed: 1980-10-31
Abstract: PURPOSE:To increase a processing speed while performing easy-to-see printing with aligned decimal-point, by starting the printing of an integer part when the input of a decimal-point key is entered. CONSTITUTION:First, a numeric key K8 is pushed and a control key KD is then pushed. As a result, an 8 is stored in the latch L in a CPU and the point position of a decimal point is set at the 8th digit from the left margin of a printing form P. With a numeric key K1 pushed, a 1 is stored in a register KR and with a K2 depressed, a 2 is also stored in the KR to display a 12 on a display device DSP. Simultaneously, the frequency 2 of the depression of numeric keys is stored in a counter C. When a decimal-point key KP is pushed, the CPU substracts the numeral 2 in the 6th digit from the left margin to start printing operation. During the printing operation, numerals 3 and 4 following the decimal point may be inputted.

Filed: 1999-05-31
Abstract: PROBLEM TO BE SOLVED: To reduce the complexity in the design and control of a reference cell by comparing charge states with each other, and by generating a two-bit signal for coding the charge states by the output. SOLUTION: In the case of both erased memory cells, even when cells F1 and F2 adsorb different current, mirroring is made in first and second current mirror circuits 19, 20, 33, and 34, and voltages 01 and 02 are set to a high level for corresponding to a logic state '11'. In the written cells F1 and F2, the cells do not adsorb current, and current being mirrored in first and second current mirror circuits 19, 20, 22, and 23 is insufficient to reduce the voltage in I/O nodes 41a and 41b. The output voltages 01 and 02 correspond to a logic state '00'. In the case of the cells F1 and F2 being similarly erased and written, respectively, and in the case of the cells F1 and F2 being written and erased, respectively, the each logic state is set to '10' or '01'.

Title: Ultrasonic parametric loudspeaker
Inventor: ARIKAWA YASUSHI
IPC: H04R3/00
Filed: 1991-05-28
Abstract: PURPOSE:To make the loudspeaker thin in profile and to make the size small by arranging a reflection material reflecting a primary sound wave more than a secondary sound wave to the speaker and allowing a sound absorbing member to reflect and absorb the primary sound wave. CONSTITUTION:An ultrasonic wave generating means 1 is formed by arranging lots of ultrasonic wave vibrators 1a to a base 1b. Moreover, a film-made reflection material 5 is provided to a side of the generating means 1a from a sound wave incident face 3a of an acoustic filter 3. The material 5 reflects a primary sound wave made incident in the filter 3 in the inside of a speaker and the energy is absorbed to the absorbing material 4. Then the interruption quantity of the primary sound wave required for the filter 3 is made smaller than the case without the material 5. Furthermore, since the reflection material 5 decreases the reflection capability of the secondary sound wave, the filter 3 is made thin without deteriorating the performance of the ultrasonic parametric loudspeaker A. Thus, the loudspeaker is made small and thin.
