Title: Self cleaning type baking and roasting oven - has sides indented outwards to increase strength of enamelling
IPC: F24C15/00
Filed: 1971-02-12
Abstract: The oven body is a rectangular cube with a flange at the front and a door is hinged to this. The sides, top, bottom and back are all indented outwards with diagonal edges so that each of the sides is a shallow pyramid or cone with two sloping triangular and two sloping trapezoidal sides. The inside surfaces are enamelled. The result of the indentation is that when the oven is heated to self-cleaning temperature all the consequent thermal stresses are compressions and not tensions and this in turn reduces the incidence of cracking in the enamel which is more resistant to compression than to tension.

Title: Automatic camera without exposure meter - has set of differing electro-magnet pole pieces with each piece corresponding to an exposure factor
IPC: G03B7/081
Filed: 1972-07-15
Abstract: The shutter operating electromagnet is fitted with a set of pole pieces pivoted on a common axis and with the electromagnet connected to an exposure circuit. The current in the exposure circuit pulls in a set number of pole pieces, with each pole piece requiring an increasing pull. The pole pieces are fitted with differing cams whose setting is monitored by an exposure setting control which doubles as the shutter action control lever. No other moving parts are thus required, especially a moving coil meter which suffers from vibrations. The circuit is simple and efficient and is easily bypassed for manual control by suing a shaped cam to select the exposure and set the controls.

Patent JP-H0438578-B2 (JP)
IPC: B24B49/16
Filed: 1989-02-02
Abstract: Apparatus for improving tire uniformity includes contra-rotating grinding wheels (32, 34) for removing tire material from the upper and lower shoulder portions of the tire (16). The grinders are moved on an assembly (18) into grinding engagement with the tire along a path that is defined by a radius of the tire to ensure that both grinding wheels at each shoulder of the tire make simultaneous contact with the tire. The amount and extend of grinding accomplished by the contra-rotating grinders is controlled by a grind control circuit. The grind control circuit measures the no-load current level of the grinder motor and compares the no-load current level with the current level when the grinder motors are under load. When the grinder current under load is above a predetermined maximum load current, the control circuit will signal the grinders to retract from engagement with the tire until the load current drops below the predetermined maximum level. When the motor load current is below the minimum operating range level, the grinders are signalled to advance into engagement with the tire until the load current reaches the predetermined minimum level. This operations is repeated in cyclic fashion until the tire has been ground a sufficient amount to bring it within an acceptable correction range. An alarm circuit which cooperates with the grind control circuit assures that once a grinding operation is begun it will have a predetermined minimum time duration. The alarm circuit also detects whether one of the shoulder grinders takes too long to engage the tire after the other shoulder grinder has made such engagement. The alarm circuit will stop the grinding operation if too long a period of time has elapsed and if there are other malfunctions of the grinders.

Abstract: PURPOSE:To contrive to reduce the maximum conduction resistance by a method wherein metallic wiring layers are provided (=side surface metallize) on the wall surface of a recess called a cavity and further connected to the second metallic wiring layer. CONSTITUTION:The electrode of a semiconductor element 1 and the first metallic wiring layers 2 are connected by Al wires, after the semiconductor element 1 is fixed on the metal surface (=island) 8 plated by Au at the bottom of the cavity 7 with the eutectic alloy of Au/Si. It is power source pins and earth pins that are restricted in the value of conduction resitance. The power source and the earth are surface-metallized on a semi-circular cutout 12 and connected to the second metallic wiring layers 5, resulting in the reduction of conduction resistance. The second metallic wiring layers are used only for the power source and the earth, and accordingly each can be formed wider than the wiring width of the first layers. Therefore, the wiring resistance of the power source and the earth can be reduced at least to less than 1/2, normally 1/4-1/5. After finishing in connection of all the wires, a sealing ring 9 is covered with a metallic cap and sealed by a seam welding method or Au/Sn alloying method.
