Title: Semiconductor wafer
Inventor: MARUYAMA TAKATOSHI
IPC: H01L21/02
Filed: 1988-04-06
Abstract: PURPOSE:To obtain a wafer which has a large effective area and capable of being matched with an automatic machine, by a method wherein, when one circle and another circle are concentrically superposed, a wafer shape is obtained by superposing the latter circle on a wafer plane, the former having the maximum area in a wafer plane, the latter having a diameter larger than the former and a dimension cutting the corner parts of the wafer. CONSTITUTION:When a circular type wafer 4 or 5 is required by shaping a trapezoidal or D-shaped wafer 1, 2, a circle having the maximum area in the plane of the trapezoidal or D-shaped wafer 1, 2 is determined. On the other hand, another circle is determined, whose diameter is larger than the above circle and cuts the corner parts of the trapezoidal or D-shaped wafer 1, 2. When the above large diameter circle is superposed concentrically on the circle in a wafer plane, a wafer shape is determined as a shape obtained by superposing the large diameter circle on the trapezoidal or D-shaped wafer 1, 2. Thereby, the matching with an automatic machine dealing with a circular wafer 4 or 5 is enabled as it is, without reducing the effective area of water.

Title: Clutch and clutch control method of single-tub washing machine
Inventor: HIROOKA HIROSHI
IPC: D06F37/40
Filed: 1994-04-22
Abstract: PURPOSE:To enable a washing machine to switch functions between washing and dehydration by reversely magnetizing an electromagnet to attract or repulse a permanent magnet fixed to the clutch disk, and to prevent the clutch from changing over irregularly while washing. CONSTITUTION:During washing or rinsing, electricity of leveled and specified waveform is run through an electro-magnetic coil 10, and a core 22 is magnetized as south pole to attract an permanent magnet 20. A clutch disk 19 is raised so as to pull a clutch pin 21 off the notch 13 of a clutch plate 12 and free the connection of a dehydration shaft 16 and a washing shaft 11. Then, a clutch pin 21 is passed through a guide hole 18 of a guide plate 17 so as to prevent the clutch disk 19 from detaching off the guide plate 17. After that, a washing tub 3 is filled with water, and the washing shaft 11 alone is rotated by a motor 5 to carry out the washing. As a result, the switching of the clutch is prevented even when the accidents such as a power failure and disconnection to the electromagnetic coil 10 take place.

Title: Heat insulation device in semiconductor integrated circuit device
Inventor: KIKUYAMA SEIICHIROU
IPC: H01L23/58
Filed: 1984-04-25
Abstract: PURPOSE:To protect an IC safely even when the state of a high temperature is continued for a prolonged time by constituting a simple circuit in which thermal hysteresis is applied to a protective circuit and reworking is prevented up to a low temperature. CONSTITUTION:Predetermined transistors (elements Q) are connected to a constant current circuit 1 according to a prescribed method. Constant currents I1, I2 are produced by P-N-P elements Q10, Q12 for constant currents, and I0=I1-I2 holds by N-P-N elements Q13, Q16 forming a current mirror circuit. When an N-P-N element Q8 for thermal sensing is turned ON once by a temperature rise, an N-P-N element Q18 for thermal sensing is turned ON through a P-N-P element Q6 for an output, the N-P-N elements Q13, Q16 are turned OFF, and I2=0I0=I holds. Consequently, reference voltage applied to a base in the Q8 is made higher than first one, and the Q6 keeps ON until VBE lowers to the reference voltage. That is, the operation of a circuit connected to an toutput terminal 200 is interrupted until a temperature reaches to a second set value. When the Q6 is turned ON, base currents flow through the element Q18 for hysteresis and the element Q18 turns to On state. Accordingly, an IC being operated at a high temperature for a prolonged time can be protected thermally by thermal hysteresis operation.
