IPC: H01L21/027
Filed: 1986-07-15
Abstract: PURPOSE:To enable an ultra-high pressure mercury lamp to be cooled down correctly by a method wherein the power consumption of said mercury lamp is adjusted according to the fluctuation in radiating light quantity of the mercury lamp to compensate this fluctuation, simultaneously cooling down the lamp with cooling air flow corresponding to the level of power consumption. CONSTITUTION:An ultra-high pressure mercury lamp 1 is cold-controlled by adjusting the revolution of a fan motor 13 of a fan 12. The cooling air flow in the first step A and the second step B is respectively specified to be at high and low level corresponding to the power consumption of ultra-high pressure mercury lamp 1 so that said mercury lamp 1 may be cooled down by the optimum cooling air flow corresponding to respective power consumption at every repeated step of A and B. The revolution of fan motor 13 can be controlled by a variable frequency inverter 43 of a fan motor drive circuit 40 enabling the ultra-high pressure mercury lamp 1 to be cooled down correctly correspondingly to the fluctuation in power consumption.

Title: Soldering device for semiconductor element
Inventor: OGAWA YOSHIE
IPC: G02F1/1345
Filed: 1983-09-09
Abstract: PURPOSE:To prevent the cracking of a plate by heating a semiconductor element through the irradiation of infrared rays and heating a semiconductor element section in the plate by hot air. CONSTITUTION:The hot air of an inert gas such as N2 gas forwarded into an inner cylinder 12 through a heater 18 from a valve for a hot air feeder 16 is blown against the lower surface of a plate 1 through the holes 12a, 12b of the inner cylinder 12 and the slit 10a of an outer cylinder 10. Infrared rays are irradiated to the upper surfaces of semiconductor elements 2 through the holes 3a of a mask 3 from an infrared irradiator 5. Consequently, the temperature of element 2 sections in the plate 1 also rises because the elements 2 are heated through the projection of infrared rays and the element 2 sections in the plate 1 are heated by hot air. Accordingly, temperature differences among the elements 2 and the plate 1 are reduced, the cracking of the plate 1 is prevented, and the elements are soldered uniformly.

Title: Antenna and radio equipment provided with same
Inventor: TAKETOMI KOICHI
IPC: H04B1/38
Filed: 1993-06-11
Abstract: PURPOSE:To secure water resistance and moisture resistance while keeping a high transmission/reception efficiency by coating a nonconductive paint and oil or vinyl to a surface of an antenna main body whose surface layer is made of a high conductive material. CONSTITUTION:An insulating material 24 such as a paint of lacquar, vanish or the like or rust-proof insulating material such as a nonconductive oil or a vinyl are applied or coated to a surface of an antenna main body 23 made of a high conductive material such as copper or silver. Thus, a current produced at transmission/reception does not flow to the insulating material 24 but flows only to the main body 23, then the rust-proof effect is realized and a high transmission/reception efficiency is maintained. That is, a radio wave transmits through the insulation material 24 and the current flows only to the main body 23 at transmission/reception. Since the current does not flow through a part with a bad conductivity, the high efficiency is maintained.

Title: Clock synchronizing up-down counter
Inventor: TAKAHARA TORU
IPC: H03K23/00
Filed: 1984-08-07
Abstract: PURPOSE:To realize the same function with a smaller scale of circuit by adopting the circuit constitution using a D flip-flop (DF/F) in place of using a J/K flip-flop. CONSTITUTION:When an enable signal E is logical 0, DF/F21-24 keep the pre-state even with a clock CK input and the count is stopped. When the enable signal E is logical 1, the input of a D/U signal controls outputs of EX-OR gates 29-32. When the D/U signal is logical 0 and the clock CK is inputted at Q1= ''1'', the DF/F22 is inverted and the pre-state is kept at Q1=0. When the clock CK is inputted at Q1=Q2=''1'', the DF/F23 is inverted and in other cases, the pre-state is kept. The DF/F24 is inverted to the input of the clock CK only at Q1=Q2=Q3=''1'' and the pre-state is kept in other cases. That is, the counter acts like a clock synchronizing up-counter. While the D/U signal is logical 1, the counter acts as a clock synchronizing down-counter.

Title: Formation of resist pattern
Inventor: TANIGUCHI HIROYUKI
IPC: H01L21/30
Filed: 1985-07-26
Abstract: PURPOSE:To obtain a good configurational accuracy for the title resist pattern and high resistivity for etching by a method wherein the prescribed pattern is exposed on a photosensitive resist film, and when a resist pattern is going to be formed by hardening after developing, rinsing and drying work is performed, temperature is raised in a step-like manner. CONSTITUTION:A photosensitive photoresist film is coated on the surface of the silicon wafer to be used for manufacture of an IC, and then exposing, developing, washing and drying processes are performed thereon. The silicon wafer 1, wherein a non-hardened resist pattern is formed, is moved to split type hot plates 301-305, and they are moved to the hot plates in the direction as shown by the arrow in the diagram. If the set temperature is raised as going to the downstream of a semiconductor wafer, the semiconductor wafer 1 is moved to the heated region of relatively high temperature from the heated region of relatively low temperature, and the non-hardened pattern on the surface is heated up to a high temperature gradually and hardened. As a result, the final heating temperature can be raised without deterioration of the pattern form, and the formed resist pattern has sufficient resistivity against a reactive ion etching.

Title: Method of transmitting message having specified message duration from battery-less transponder to interrogator
Inventor: YOZEFU EICHI SUKUERUMAN
IPC: G07C9/00
Filed: 1990-06-22
Abstract: PURPOSE: To obtain information concerning to an animal by an arrangement wherein a high frequency interrogation pulse for requesting transmission of a message can be transmitted to a transponder in response to an interrogation command validated in an interrogator. CONSTITUTION: Assuming a limited area, e.g. a pigpen, a large number of animals can stroll freely therein. Interrogators for transmitting a high frequency pulse at a constant interval are set fixedly at several points. The interrogator can receives a message through an antenna 10, demodulate the message and evaluate the message in a processor 22. A transponder has a carrier frequency identification circuit 24 in order to prevent transmission of a high frequency interrogation pulse at a moment of time when another interrogator just retains a response from the transponder and notifies presence of another carrier frequency signal. Consequently, the processor 22 actuates a high frequency interrogation pulse source only thereafter.
