Title: Ultrasonic wave flaw detector
Inventor: UCHIDA KUNIHARU
IPC: G01N29/04
Filed: 1987-09-11
Abstract: PURPOSE:To make it possible to detect flaws along the entire region from the surface of a material to the deep part, by providing an array probe, a probe, a receiver and the like. CONSTITUTION:An ultrasonic wave signal, which is received with a probe 19, is sent to a receiver 21 and amplified. The signal undergoes appropriate frequency filtering. Thereafter the signal is sent to a signal processor 22. A waveform signal of a detected flaw is taken out after the signal processing such as waveform detection. The waveform signal of the detected flaw, which is obtained by the signal processing in the processor 22, is sent to a sweep signal generator 18. In addition to a pulse signal 17, ultranosic-wave-beam controlling condition data 23 from a computer 16 are imparted to the generator 18. The data 23 comprise the following data; delay time data of a sweep signal X, which is operated in the computer 16; and time domain data, which perform luminance modulation of a CRT. In this way, an ultrasonic wave beam from an array probe 12 can be inputted in a broad range from the vicinity of the surface of a material 11 to the deep part, and the effective flaw detection can be carried out.

Title: Manufacture of grain oriented silicon steel sheet with high magnetic flux density
Inventor: YAMAGUCHI HIROSHI
IPC: H01F1/16
Filed: 1996-08-29
Abstract: PROBLEM TO BE SOLVED: To obtain a product having high magnetic flux density and excellent in iron loss characteristic by allowing compounds of specific elements to adhere to the surface of a steel sheet in the step after primary recrystallization annealing and before the application of a separation agent at annealing and then performing the decomposition treatment of the compounds.

The grain oriented silicon steel sheet is manufactured by a method consisting of a seriese of stages mentioned above. In this manufacturing method, compounds of one or >=2 elements selected from the group No. 13 to 15 and the period 4 to 6 elements of a periodic table of elements are allowed to adhere to the surface of the steel sheet after the primary recrystallization annealing and before the application of a separation agent at annealing, followed by decomposition treatment of the compounds.

Title: Internal planetary gear structure
Inventor: TAKAHASHI ATSUSHI
IPC: F16H1/32
Filed: 1991-08-13
Abstract: PURPOSE:To improve the extent of accuracy after completion of assembly even if machining takes place with a machine of the same degree in terms of accuracy of finishing, in a speed variable gear provided with an internal planetary gear structure. CONSTITUTION:External gears (for example, a1 and, a2, b1 and b2, c1 and c2) cut in the same position are made so as not to be engaged with an internal gear (of an outer pin 111) simultaneously at the time of operation. With this constitution (in contradiction to the conventional idea that the external gear cut in the same position is engaged with an internal gear simultaneously at the time of operation, however), accuracy is made so as to be improved so well after completion of actual assembly. In this case, each difference in tooth numbers of external gears 105a, 105b and between these external gears and the internal gear (the outer pin 111) should be set to the number of integral times over the number of the external gear. If so, various holes to be formed in both external and internal gears of these external gears 105a, 105b can be made to be machined simultaneously (at one time setting), accuracy in positional relations between the external gears and these various holes is improved by leaps and bounds.

Title: Output buffer circuit
Inventor: OHASHI KATSUNAO
IPC: G01R31/28
Filed: 1998-08-13
Abstract: PROBLEM TO BE SOLVED: To provide an output buffer circuit by which the turning-on-and-off time, a three-state buffer circuit and the delay time of an internal interconnection can be measured precisely in an ordinary interconnection route by a method wherein a pull-up transistor and a pull-down transistor which are controlled so as to be turned on and off by a test control signal are connected to the output of the three-state buffer circuit. SOLUTION: In the case of a test, the low-to-high-impedance state (HiZ) of a three-state buffer circuit 3 is measured in such a way that a pull-down transistor 2 for test is turned off and that a pull-up transistor 1 for test is turned on. When a level LOW is given to the input of the three-state buffer circuit 3 as data, and the three-state buffer circuit 3 is set to a disable state from an enable state. Then, its output terminal is shifted to a level HIGH from the level LOW. In a test circuit by this invention, the pull-up transiator 1 and the pull-down transistor 2 can be turned on and off when the output of the three-state buffer circuit 3 is tested. As a result, the turning-on-and off time of the output of the three-state buffer circuit 3 and the delay time of an internal interconnection can be measured precisely in an actual interconnection route.

Title: Control device for clothes drier
Inventor: MIHARA MASAMITSU
IPC: D06F58/28
Filed: 1989-09-04
Abstract: PURPOSE:To perform a dry control of high accuracy with no influence by a room temperature by determining the dry time on and after by the time, in which a temperature difference between a circulative air inlet temperature and the room temperature reaches a predetermined time after starting operation, and by the room temperature, in an action control part. CONSTITUTION:When assumed T for the time before a temperature difference between a circulative air inlet temperature and a room temperature reaches a predetermined temperature difference Ta, the dry time T1 on and after is determined in accordance with the room temperature. The dry time T1 is automatically set by an action control part so as to be increased at the time of the low room temperature and decreased at the time of the high room temperature. For instance, in the case of the time T 1hr 30min and the room temperature 20 deg.C, 29min is obtained with the adequate time T1 corrected in accordance with the room temperature. The time T1, which is increased in the case of the low room temperature, is almost in proportion to the time T till the time reaches the temperature difference Ta, and correction is performed with no influence by the room temperature so that a dry factor is not less than 100% at the time of ending drying. In this way, the drying can be automatically ended by performing an operation control of high accuracy without being influenced by the room temperature when a clothes drier is in operation.

Title: Porous body type heat exchanger and facilities where they are employed
Inventor: FUNABASHI KIYOMI
IPC: F28B1/02
Filed: 1991-09-09
Abstract: PURPOSE:To obtain a high efficiency heat exchanger which uses a hydrophobic porous film. CONSTITUTION:A large number of heat exchanger tubes made of a hydrophobic porous material 2, which allows the penetration of steam into the material but allows no penetration of liquid, are bundled. A low temperature fluid 1, which is liquid, is passed inside the heat exchanger tubes while a high temperature fluid 2, which is liquid or steam, is passed outside the heat exchanger tubes. It is acceptable even if this internal and external relation is opposite. When the high temperature fluid 2 is liquid, the liquid is vaporized and turned into steam, which penetrates the porous material and enters the low temperature fluid side where it is condensed and turned into liquid. The liquid itself which is a high temperature fluid is unable to penetrate the porous material. When the high temperature fluid is steam, the steam is partially condensed on the high temperature fluid side and turned into liquid drops. The liquid drops thus produced are unable to penetrate the porous material as well. In this manner, heat is transferred from the high temperature fluid 2 to the lower temperature fluid 1. The heat transfer based on thermal conduction of the porous body 2 is added to this heat transfer mechanism as well. It is, therefore, possible to inhibit the penetration with the porous material and prevent the mixture into the low temperature fluid even when there exist impurities in the fluid.
