Title: Semiconductor memory element and memory circuit
Inventor: IIZUKA HISAKAZU
IPC: G11C16/04
Filed: 1978-12-14
Abstract: PURPOSE:To realize the low voltage, high-speed writing and high density each by providing three sets of electrodes containing the fixed address selection extending to the insulator film between the conductive source and drain regions and also applying previously the DC voltage to the control electrode. CONSTITUTION:Floating electrode 25 covering over part of insulator oxide film 24, control electrode covering over part of electrode 25 and address selection electrode 29 the extended part of which covers over film 24 are laminated on film 24 provided between source and drain regions 22 and 23 of p-type Si substrate 21 and featuring the lower impurity density than these regions 22 and 23 and via oxide films 26 and 27. Thus the gate electrode is formed. With previous application of the fixed DC voltage to electrode 27, the high-speed writing becomes possible owing to existence of the high electric field. At the same time, the writing pulse applied to region 23 and electrode 29 can be set to a low level of voltage since the extension part of electrode 29 forming the effective channel is set close to substrate 21. Furthermore, the trap capacity can be omitted by applying previously the voltage to electrode 27 along with the low voltage, thus realizing a high density for the memory device.

Abstract: PURPOSE: To simplify the constitution by dispensing with a booster transformer secondary side high voltage detecting winding in order to detect an abnormal condition where a magnetron is not oscillated at an inverter starting. CONSTITUTION: A booster transformer 4 furnishes only a winding to drive a magnetron 5 but does not furnish a secondary side high voltage detecting winding. The output of the first transformer 7 to detect the output current of a booster transformer, and the output of the second current transformer 11 to detect the input current of a commercial power source, are compared with a specific third standard voltage given by the third standard voltage generating circuit 20 through a comparing circuit 19. When a magnetron is not oscillated in a high-frequency heating process when an inverter circuit 2 is started, the consumption power is reduced so as to reduce the output of a current transformer, and an abnormal condition can be detected. The second standard voltage given by the second standard voltage generating circuit 14 is reduced, and the control by the output of a collector voltage detecting means 10 is given the priority, so as to control the conducting time of a switching element 9 smaller than a normal operating condition.

Title: Manufacturing method for laminated type solar cell
Inventor: ISHIMURA TAKESHI
IPC: H01L31/04
Filed: 1989-06-19
Abstract: PURPOSE:To enable higher efficiency by forming an n-type crystallite silicon (muc-Si) semiconductor layer based on a glow discharge decomposition process where argon gas is added to a reaction system. CONSTITUTION:In the formation of an n-type muc-Si film 5, a slight amount of argon gas is introduced to a reaction system. Specifically, 1 to 10%, preferably 3 to 5% of argon gas is introduced to dilution hydrogen. Introduction of argon gas, if its amount is appropriate, makes it possible to crystallize down to 150Angstrom , although sufficient crystallization less than 250Angstrom  is impossible without introducing argon gas. Moreover, when it is fine crystallized, the ohmic performance of pn conjunction can be maintained. It is, therefore, possible to further reduce its thickness of film and minimize photo absorption loss and improve conversion efficiency without the loss of electric conductivity.
