Title: Semiconductor non-volatile memory
Inventor: WATANABE TOMOYUKI
IPC: H01L27/112
Filed: 1978-11-29
Abstract: PURPOSE:To provide an I<2>L with non-volatile memory function by forming a p- type control layer close to the base layer of NPN-transistor of I<2>L and further providing a floating gate through an insulator film on the substrate surface between the both layers. CONSTITUTION:A floating gate 23 is provided through an insulator film 22 between the base layer 15 and the control layer 21 in an NPN-transistor. The layer 14 consisting of word line is p-type isolation layer and common with I<2>L in the direction of word line. When no electrons are present in the gate 23, it functions as normal I<2>L. The presence of electrons in the gate 23 allows channel to be formed in n-layer 25, holes to be flowed from p-layer 13 to p-layer 21, and the base current to reduce thereby reducing the collector 16 current. This allows the amount of electron accumulated in the gate 23 to be detected as the change in the collector current, enabling memory operation. To perform writing, pn-junction of the layers 21 and 14 are subject to breakdown to allow electron injection. For reading, designated word line is made to zero potential and other word lines to a high level. To erase the memory, ultraviolet ray is irradiated on the element.

Title: Treatment apparatus
Inventor: YAMAZAKI AKIHITO
IPC: H01L21/31
Filed: 1986-06-25
Abstract: PURPOSE:To facilitate treating the surfaces of objects to be treated uniformly by a method wherein a plurality of the types of material gases and their reaction product gases are completely mixed in a space separated from a reaction tube by a shielding plate and then supplied into the part where the objects to be treated are placed. CONSTITUTION:By forming a through-hole 10 in a shielding plate 9 which separates a part where a nozzle 3 is provided from a part where wafers 2 are placed, mixing ratios of material gases and their reaction product gases can be substantially improved and, at the same time, the gases can be supplied into the part where the wafers 2 are placed under completely mixed state. Moreover, as mixing ratios of a plurality of types of material gases can be significantly improved, the gases can be supplied into the part where the wafers 2 are placed under the state wherein the reaction is almost perfectly completed. With this constitution, if flows of the material gases are predetermined beforehand, the reaction product gases corresponding to the material gases can be produced and the gas atmosphere in the wafer part can be very reproducible and variation of the film thicknesses of the surfaces of the wafers among the batches can be suppressed.

Title: Nuclear reactor control rod
Inventor: UEDA KIYOSHI
IPC: G21C7/10
Filed: 1988-06-16
Abstract: PURPOSE:To improve reactivity value of a control rod while contriving the long life thereof by filling a thin wall metal tube with high reactivity type neutron absorber and arranging the filling inner tube at the position at which subcritical degree of a reactor core is shallowest or in the neighborhood thereof. CONSTITUTION:The wing 11 of a nuclear reactor control rod 10 is divided into three areas l1, l2, l3 along a longitudinal direction. Long life type neutron absorber 20 such as a hafnium rod is inserted in each housing hole because the middle area l2 is high neutron irradiated one and large reactivity is not needed. The area of l2 an inserting edge side adjacent to the area l1 is the necessary part of high reactivity value and high reactivity type neutron absorber filling inner tubes 21 are inserted in each housing hole of the area l2. Since an inserting edge area l3 adjacent to the area l2 does not need high reactivity, neutron absorber 22 such as natural boron as well as the same as the conventional fills each housing hole 18. Thereby a neutron absorbing quantity of the high reactivity area can effectively be ensured, big reactivity and long life can be contrived.

CONSTITUTION:In order to pattern the second and third layers 4, 5 on the first layer (lower layer organic material layer) 2 on the silicon substrate 1 further to process the first layer 2, the frequency of RF bias is kept at 800KHz-2 MHz until the upper part surface 8 of the silicon substrate 1 is exposed while said frequency is kept at 27.12 MHz-100MHz to perform the two stage etching steps after the upper part surface 8 is exposed. Through these procedures, during the etching step in the latter stage, the frequency is increased, the ion follow-up capacity is decreased and the ion impulse is relieved so as to reduce the re-sputtered adhesive.

Abstract: PURPOSE: To produce a reinforced plastic which has an excellent shaping property and can be hardened at room temperature in a desired time, by impregnating a hardener into a reinforcing fibrous material, then impregnating a liquefied resin into the material, laminating such fibrous materials with one another and hardening the resin.  
     CONSTITUTION: A hardener such as benzenesulfonic acid, paratoluenesulfonic acid, hydrochloric acid, maleic anhydride, phthalic anhydride, formaldehyde, organic peroxide or amine is selected depending on the kind of a resin to be used. The  selected hardener is impregnated into a reinforcing fibrous material such as a glass  cloth or asbestus so that the quantity of the hardener becomes normally 0.5W30  parts by weight as against 100 parts by weight of the effective part of the resin.  The hardener is dried if necessary. A liquefied resin such as urea resin, melamine  resin or resol-type hpenolic resin is then impregnated into the fibrous material. Such  fibrous materials are laminated with one another. The resin is hardened. A reinforced plastic is thus produced under good work conditions.

Title: Call time limiting system for telephone set
Inventor: SUZUKI MASAHIKO
IPC: H04M15/02
Filed: 1988-06-15
Abstract: PURPOSE:To effectively prevent a long telephone call by limiting a call time and prohibiting re-transmission for a constant time when the call is forcibly disconnected according to the passing of the limiting time. CONSTITUTION:When a calling person hung up a transmitter and a handset 7 and a hook switch 6 is closed, an MPU 8 judges whether a timer TM is set or not. When the timer is not set, a direct current loop is closed to a telephone line l and the telephone line l is closed. When a called person executes a response, the timer TM is set for the specification of the call time and time counting is started. When the timer TM counts a first setting time t1 before the end of the call, a previous notice tone is sent to the transmitter and receiver 7 and after that, the direct current loop is closed. When the handset is off-hook again and the timer TM does not count a second setting time t2, transmission is impossible.
