In the region of a part on the drain 6, the recess region of an insulating and isolating field oxide film 4 is covered so as to face the drain 6 through a second thin gate film 8. The width (w) of the recess region is twice or more the thickness of a polycrystalline silicon layer, in which the floating gate is formed. Therefore, the surface of the floating gate polycrystalline layer has a recess region having a depth (d) like the field oxide film. The surface area is increased by the step difference, i.e., the side surface of the recess region. A control gate 11 faces the floating gate through a third gate oxide film 10 even in the step part of the recess region in the floating gate. Thus the capacitance between the floating gate 9 and the control gate 10 can be made large, and high-speed, stable writing and erasing characteristics are obtained.

Title: Defrosting device
Inventor: KOIKE TADAO
IPC: F24F11/02
Filed: 1985-05-20
Abstract: PURPOSE:To increase defrosting efficiency by a method wherein defrosting is effected when a temperature difference between a temperature sensor at the refrigerant pipeline side of an outdoor heat exchanger and another temperature sensor at the downstream side of air has become higher than a set value in a heat pump type air-conditioning machine. CONSTITUTION:During room-heating operation, heat is absorbed from atmosphere by the outdoor heat exchanger, however, frost attaches and grows in case the atmosphere is of low temperature and high humidity. Here, the temperatures of the atmosphere, the refrigerant pipeline and air at downstream side Ta, Tb, Tc becomes large. When the temperature difference Tx has become larger than a set value, defrosting is effected by utilizing above-described characteristic. Thus, the deterioration of room heating capacity due to clogging of frost in the outdoor heat exchanger 5 may be prevented and the idle defrosting in case of low temperature and low humidity without frosting may also be prevented and stabilized room-heating capacity may be maintained.

Abstract: PURPOSE:To obtain a bounce photographing device for setting an irradiating direction to a light emitting part for executing the bounce photographing by moving automatically the light emitting part of a stroboscopic device by detecting the condition for executing the bounce photographing. CONSTITUTION:When a titled device reaches a broken line position, on the way of movement by the rotation of motor 16 of a light emitting part 18, a switch 20 goes to an off-state, one of input terminals of an AND circuit 32 goes to a low level, and an output of the AND circuit 32 which is a high level is inverted to a low level. Accordingly, a transistor which is in a conducting state until that time is inverted to a non-conducting state, and at the same time, a transistor 8 also goes to a non-conducting state. In such a case, as for a state of the other AND circuit 33 of a driving controlling circuit 31, a photodetecting device 30 continues a high level output, and a transistor 11 remains in a non-conducting state, therefore, feed to the motor 16 is stopped, the rotation stops and the light emitting part 18 stops at a broken line position. In such a way, the light emitting part 18 of the stroboscopic device goes to a state that the bounce photographing can be executed automatically, when some reflecting object exists at a short distance and photographing using a desirable stroboscopic device can be executed.
