Title: Microwave oven
Inventor: KITADA YUKIHIRO
IPC: H05B6/72
Filed: 1999-10-01
Abstract: PROBLEM TO BE SOLVED: To provide a microwave oven in which sufficient heating can be carried out while utilizing detection results of a detecting means effectively. SOLUTION: The microwave oven 20 comprises a magnetron 31 and an infrared sensor 9 disposed above a heating chamber 27. Microwave oscillated from the magnetron 31 is supplied through an waveguide 32 and a radiation antenna 34 to the heating chamber 27. The radiation antenna 34 is turnable. The infrared sensor 9 detects temperature of an article to be heated by detecting the quantity of infrared rays within a field of view 9a. The radiation antenna 34 has a width limited at the part entering the field of view 9a as compared with other parts. Consequently, the time required for the radiation antenna 34 to traverse the field of view 9a is shortened.

Title: Grill structure for vehicle
Inventor: WAKAMATSU JUNICHI
IPC: B60R19/52
Filed: 1996-10-02
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of wind noises by shifting a die dividing line between front and rear dies back and forth over a longitudinal direction when a grill is formed integrally with an externally loaded part item by aligning a mother die with an air flow opening provided in the externally loaded part item. SOLUTION: For use for a radiator grill as an externally loaded part item, a die dividing line 11 provided along the longitudinal direction of a grill 10 is formed to be recessed and projecting having the same pattern from the upper end to the lower end of the grill 10. Thus, the position of a level difference 12 formed in the rear side of the die dividing line 11 is shifted back and forth by the recessed part 11a and the projecting part 11b of the die dividing line 11. Thus, by shifting back and forth the positions of 13a vortex flow 13a and 13b formed in the rear side of the die dividing line 11 with the recessed and projecting parts 11a and 11b so as to shift the growth of the vortex flow 13a and 13b, the vortex flow 13a and 13b are made to form a small swirl block and, by mutual interference between the vortex flow 13a and 13b, a force is reduced and wind noises are suppressed.

Abstract: PURPOSE: To prevent peeling and cracking at low melting glass-lens sealing boundary and low melting glass-metallic holder sealing boundary by setting the coefft. of thermal expansion of the low melting glass slightly smaller than the coefft. of thermal expansion of the metallic holder. CONSTITUTION: A lens 1 is inserted into a metallic holder 2 having a lens placing part 21 and is fixed by low melting glass 3 essentially composed of lead glass so as to prevent the mispositioning of the lens at the time of firing. In such a case, the material of the metallic holder 2 is made of a martensitic stainless steel or ferritic stainless steel and the coefft. of thermal expansion is set approximate to the coeffts. of thermal expansion of the lens 1 and the low melting glass 3 and, therefore, slight stresses are merely applied on the sealing boundary 4 between the metallic holder 2 and the low melting glass 3 and the sealing boundary 5 between the low melting glass 3 and the lens 1 at the time of a temp. change. Further, the coefft. of thermal expansion of the low melting glass 3 is set slightly smaller than the coefft. of thermal expansion of the metallic holder 2 and, therefore, the metallic holder 2 is held in the state of lightly pressing the low melting glass 3 at ordinary temp.

Title: Thermal printer
Inventor: MASUKO KAZUYUKI
IPC: B41J2/375
Filed: 1985-12-18
Abstract: PURPOSE:To enable a thermal head to be used for a long period of time, by setting a voltage supplied to heat generating elements of the thermal head to a low level in a period in which a controlling circuit is reset. CONSTITUTION:A terminal voltage Vc of a capacitor C in a resetting circuit 18 is inputted to a minus input terminal of a comparator 23, while a voltage Vref obtained by voltage division by resistors R2, R3 is inputted to a plus input terminal of the comparator 23. While the terminal voltage Vc of the capacitor C is lower than the comparative voltage Vref, an output voltage of the comparator 23 is at a high level (+5V), and an output from an inverter buffer 24 is at a low level. Therefore, an electric current passed from the point of +5V to a resistor R6 wholly flows into an output part of an inverter,and a transistor Q1 is turned OFF. Where the transistor Q1 is turned OFF, a transistor Q2 is also turned OFF, and a supply voltage V0 for heat generating resistors of a thermal head is not outputted.

Title: Graphite crucible for pulling up single crystal
Inventor: KANO MASATO
IPC: H01L21/208
Filed: 1994-11-17
Abstract: PURPOSE: To suppress the adhesion of a graphite crucible to a quartz crucible even if the molten semiconductor material of Si, etc., intrudes into the clearance between the matching faces of both crucibles and to prevent the breakage of the graphite crucible by specifying the roughness of at least the upper part of the inner surface of the graphite crucible for pulling up a single crystal. CONSTITUTION: At least the upper part 24 of the inner surface of a graphite crucible 10 for pulling up a single crystal split in two is roughned or flawed. In this case, the surface roughness Rmax is controlled to >=30μm, and the surface flaws having >=30μm depth are formed on >=50% of the unit surface area. Consequently, the molten raw semiconductor material intruding accidentally into the clearance between the matching faces of the graphite crucible is transmitted in the recess of the graphite crucible, spread over the inner surface, absorbed and converted to SiC, hence the graphite crucible is not adhered to the quartz crucible, and the graphite crucible is not broken.
