Title: Thermoelectric transducer
Inventor: SETO SATOO
IPC: F25B21/02
Filed: 1997-06-25
Abstract: PROBLEM TO BE SOLVED: To avoid cracking a device by mounting a thermal stress relaxing member slidably between an electrode and a thermoelectric transducer to allow this transducer and relaxing member to follow up the deformation due to the temp. difference between opposed substrates. SOLUTION: A thermal stress relaxing member 10 is bonded to a thermoelectric transducer 3. The member 10 is formed as a cone 11 to reduce a part near electrode 6 with a convex spherical part 12 formed at the top of the cone 11, spot facings 30 with concave spherical recesses 31 at their centers are formed into the opposed upper and lower electrodes 6, thus making the member 10 slidable between the electrode 6 and transducer 3. This avoids stressing the transducer 3 as the member 10 rotates around the spherical part 12 of the electrode 6 if the top and bottom relative center positions of the transducer 3 change due to the thermal deformation of a heat exchange board 1.

IPC: B01F3/04
Filed: 1994-07-21
Abstract: PURPOSE: To give a prescribed annular orifice to a stream of water and also to release particles that have been filtered to eliminate the problem of clogging by elevating and lowering a movable disc caught in a spacer ring between a flanged joint and a ring with the inflow and cutoff of water. CONSTITUTION: A nozzle is provided with flanged joint 1 holding a spacer ring 2 and a ring 3 restricting a flow channel. Also a spacer 4 supports a diffuser disc 5 to cause recirculated water to radially flow out. Furthermore, a movable disc 6 is caught in the spacer ring 2 between the flanged joint 1 and the ring 3. By the way, the movable disc 6 has plural steps or folds 7 to secure an annular clearance when it rests on a fiat surface. Then, the nozzle is fitted to an inlet joint below. Therefore, the movable disc 6 rises when water enters the nozzle to give a prescribed annular orifice to a stream of water. On the other hand, it falls when a stream of water is cut off to release particles that have been filtered.

Title: Physical interface system for logical simulation
Inventor: KIMURA KOICHI
IPC: G06F17/50
Filed: 1986-07-21
Abstract: PURPOSE:To perform digital processing by controlling the pull-up and pull-down of logical simulation by a semiconductor element. CONSTITUTION:A 3-state driver 20 generates a signal PT='0' and a signal PUD='1' at the time of the pull-up and applies '1' to a signal line BUS through a resistance R to drive an LSI parts 1, or generates a signal PT='0' and a signal PUD='0' at the time of the pull-down and applies '0' to the signal line BUS to drive the LSI parts 1. Further, a signal PT='1' is generated when neither the pull-up nor the pull-down and the drive 20 is placed in a high impedance state. Here, the signals PT and PUD are digital signals of '1' and '0', so they are easily settable by software. Further, when the pull-up or pull-down is set once, signals collide against each other between the LSI parts 1 or 3-state drivers 30 and 20. The driver 20, however, drives the resistance R to suppress a collision current within the permissible range of a current value, so neither of the parts 1, and drivers 20 and 30 is never destroyed.

Title: Defrosting system for chilled-air circulation type open showcase
Inventor: KAWAKITA TOSHIKI
IPC: A47F3/04
Filed: 1988-07-07
Abstract: PURPOSE:To restrain an increase in the temperature of goods due to the defrosting of the same, and to expedite the draining of water caused by the defrosting by effecting the defrosting by the use of a heater in the first half of a defrosting period of time while stopping the operation of a cooler during the defrosting and then effecting the defrosting by using air through the reverse rotation of an inner fan in the second half of said period in the state that the operation of the defrosting heater is stopped. CONSTITUTION:When a cold-keep state is changed over to a defrosting state by means of timer control, the operation of a cooler 10 is stopped and, at the same time, while keeping the normal rotation of an inner fan 7, power is supplied to a defrosting heater 11 to start the defrosting by the heater. When the outlet side temperature of the cooler 10 rises to turn into a state that frost begins to melt, the power supply to the defrosting heater 11 is stopped and the operation of the inner fan 7 is changed over to reverse rotation, whereby air flows from the outlet side of the cooler 10 toward the inlet side thereof, and air in a duct which is heated by the defrosting heater 11 is made to flow through the cooler 10 again to give it defrosting heat. Moreover, air having a higher heat quantity is sucked into an inner duct 4 from a median duct 5 and flows into the cooler 10 to effect the defrosting by air, whereby the draining of water caused by the defrosting is also rapidly completed. Accordingly, time of supplying power to the defrosting heater can be reduced and the quality of goods can also be maintained.

Abstract: PURPOSE:To determine whether a power semiconductor and power means are satisfactory or not by comparing an energizing condition with a reference range for a set voltage or current when a power is fed to electrically heating means for regenerating a filter for trapping particulate, from controlled voltage generating means through the power semiconductor switch. CONSTITUTION:A commercial a.c. voltage from a wall socket 51 is converted, by a voltage dropping transformer 52 and a full-wave rectifying device 53, into d.c. voltage of 24 V which is then applied to a high potential power source line 54. A controller, 8 controls semiconductor power switches 55, 56 so as to open and close the same with a predetermined timing rate and a duty rate, and feeds a power to a blower motor M and a heater 11. A voltage applied to the heater 11 is obtained with the use of a partial voltage circuit 58 which detects a potential of the power source line, and a current for energizing the heater 11 is detected by a current sensor 59. Signals therefrom is delivered to the controller 8 which therefore determines whether these signals are within allowable reference value ranges for current and voltage, which are read from a map, thereby it is possible to determine whether the power semiconductor switches and the electrically heating means are satisfactory or not.

Title: Gas detecting element for combustion apparatus
Inventor: MURAKAMI NOBUAKI
IPC: G01N27/12
Filed: 1981-10-23
Abstract: PURPOSE:To enable the realization of a gas detecting element whose characteristics are  influenced little due to the position of fitting and which is highly sensitive even at low temperature, and the improvement in poisoning performance of the element and the mechanical strength thereof, by using an oxidizing catalyst to remove a gas which does not yet react, while using a porous ceramic to control permeability. CONSTITUTION:A flat base plate 1 made of densified alumina has a square concavity 2 at the end. A metal oxide semiconductor 3 is packed in the concavity 2, while an unglazed ceramic impregnated with a catalyst is fitted on the base plate 1 so that it covers the semiconductor 3. A gas detecting element thus prepared is fitted to a burner, an exhaust pipe or the like of a combustion apparatus. When the combustion is started,  the element is heated to be operable by an ambience of high temperature. The poisoning constituents contained in the ambience are removed by adsorption by the ceramic 4, thus the deterioration of the element being prevented. In addition, components which do not yet react, contained in the ambience, are removed by the oxidizing catalyst. The  change in the composition of the ambient gas is detected as the change in the resistance value of the semiconductor 3, and the effect of the change in the temperature of the semiconductor 3 is compensated by a temperature-measuring resistor which serves also as an electrode.
