Title: Heat treating device
Inventor: KATOU TAKAO
IPC: F27B5/16
Filed: 1984-01-23
Abstract: PURPOSE:To provide a heat treating device which reduces equipment cost and cools uniformly a material to be heated with the simple constitution in which a communicating state is changed by operating change-over dampers and the inversion of the flowing direction of the cooling gas in the treating chamber is made possible. CONSTITUTION:The inside of a vessel 1 is evacuated to about 0.05Torr and after a material 5 to be heated is electrically heated 10 to a prescribed temp., gaseous N2 for cooling is supplied into the vessel 1 and is pressurized to 5-7kg/cm<2>. A circulation fan 6 and a gas cooler 7 are started. One change-over damper 15a closes a communicating port 17a to communicate a circulating duct 14a and a blow-off duct 9. The other change-over damper 15b closes a communicating port 18b to communicate a circulating duct 14b and the suction side of a cooler 4 thereby circulating gaseous N2 in an arrow direction and cooling the material 5. The circulation is made for specified time and thereafter the dampers 15a, 15b are operated by the actuation of cylinders 20a, 20b by which the communicating state thereof is changed over. The flow of the gaseous N2 is thus inverted and the material 5 is cooled. This inversion is repeated several times according to need.

Title: Wafer heating apparatus
Inventor: SEKIYA HIDENORI
IPC: H01L21/324
Filed: 1990-01-18
Abstract: PURPOSE:To enhance the control accuracy of a heating temperature by a method wherein a uniformly heating plate is formed as a structure of two layers, a member on the heating face side out of the two layers is formed of a material whose thermal conductivity is high, a member on the wafer-holding face side is formed of a material whose thermal conductivity is lower than that of the member on the heating face side and the difference in a detected temperature between both temperature-measuring elements is made large. CONSTITUTION:A uniformly heating plate 12 is formed as a structure of two layers in its thickness direction; a member on the heating face side out of the two layers is formed of a material 12a whose thermal conductivity is high; a member on the wafer-holding face side is formed of a material 12b whose thermal conductivity is low; temperature-measuring elements 14, 16 are buried respectively in the individual members 12a, 12b of the two layers. Consequently, the difference in a detected temperature between the temperature sensor 14 and the temperature sensor 16 becomes large and the S/N against a measuring error and a noise is enhanced. Thereby, the surface temperature, of a wafer 8, whose direct measurement is difficult can be presumed, and a heating temperature can be controlled stably and with high accuracy without being influenced by a gas flow or the like flowing along the surface of the wafer.

Abstract: PROBLEM TO BE SOLVED: To provide electronic equipment wherein an electronic component is made light in weight and a housing structure having heat dissipating effects is provided. SOLUTION: A box-shaped mold resin body 5 is composed of a side wall part 2 wherein a metallic heat sink 4 is embedded and a flat board part 3. A part of the heat sink 4 is exposed from the through hole and the side wall part 2 of the flat board part 3, electronic component 50 of a printed board 11 built in the mold resin body 5 is brought into contact with the heat sink 4 exposed from the through hole, and heat from an electronic component 50 is dissipated from the heat dissipating board 4. Thus, heat generated by the electronic component having a high heat quantity is effectively dissipated, temperature increase due to heat from the electronic component can be suppressed and the equipment can be made light in weight since it is composed of the mold resin body.

Filed: 1983-01-25
Abstract: PURPOSE:To perform easily preliminary soldering without using any flux by pressing a solder member directly onto the conductor surface to be subjected to preliminary soldering and melting the solder member by the heat generated by the contact electrical resistance between both. CONSTITUTION:One electrode terminal 3b of a pulse current power source 3 is connected to one end of a lead conductor 1 to be subjected to preliminary soldering.

Filed: 1995-01-27
Abstract: PURPOSE: To prevent excessive operation by outputting a single pulse each time a valve is placed in opening/closing operation and outputting an alarm signal when the number of pulses generated within a timer time exceeds a set value. CONSTITUTION: A one-shot generating circuit 5 outputs a single pulse each time the valve 1 is placed in opening/closing operation to make an open contact 2 or closed contact 3 operates, A synchronous timer 4 measures a predetermined timer time and outputs a reset signal 8.

The valve 1 is opened when the open contact 2 turns on and closed when the closed contact 3 turns on. Therefore, the on states of the open contact 2 and closed contact 3 correspond to the opening operation and closing operation.

IPC: G03C7/26
Filed: 1986-01-20
Abstract: PURPOSE:To obtain a sensitive material having improved shelf stability and superior graininess by incorporating a precursor releasing a retarding group into a hydrophilic colloidal layer and by specifying the relative humidity of storage environment. CONSTITUTION:A precursor releasing a retarding group is incorporated into a hydrophilic colloidal layer of a color sensitive material and the sensitive material is stored at <=55% relative humidity so as to correct the defect that desensitization is caused by the retarding group of the precursor decomposed partially during storage at high temp. or for a long period. The precursor used may be selected among compounds represented by formulae I-III (where A is a hetero atom substituted anti-fogging agent such as mercaptotetrazole and X is a bivalent timing group bonding to methyl through O, cleaves as X-A during processing, and releases A quickly). Thus, the shelf stability of the sensitive material can be improved without deteriorating the graininess.

Abstract: PURPOSE:To enable a superior ink absorption in recording which is compatible with a superior transparency and film strength etc. after recording, by a method wherein a porous ink absorbing layer having a void capacity of a specific range is formed on a transparent substrate. CONSTITUTION:In a recorded material for an ink jet recording, a void capacity of an ink absorbing layer is regulated to be in the range of 0.1-100mul/cm<2>, which enables a superior ink absorption in recording which is compatible with a superior transparent treatment conducted after recording. Furthermore, if the void ratio of the porous ink absorbing layer is regulated to be in the range of 0.20-0.75, it is made possible that a superior ink absorption is accomplished without uselessly increasing the film thickness of the ink absorbing layer and the ink absorbing layer is prevented from reduction in the flexibility and occurrence of cracks caused by a transparent treatment, thus a layer of high transparency can be uniformly formed by a short-time application of a transparent treatment with heat. Additionally, a void ratio controlled to be in a specified range ensures a high film strength.

Abstract: PROBLEM TO BE SOLVED: To provide a method for detecting an already laid pipe line which is capable of adapting to a long pipe line to be inspected having lots of bent sections in a simple way and determining a position of a branch section as well as a leakage position. SOLUTION: A first opening section 11 is provided to one side of a section to be inspected of an already laid pipe line 1 and a second opening section 12 is to the other side.
