Title: Semiconductor memory apparatus
Inventor: MIYAZAKI TATSUHIRO
IPC: G11C16/06
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To save a power without lowering a speed at the time of switching memories by extending an operation clock for a predetermined period when a non-operation state is selected while a steady-state current shutoff means for shutting off a steady-state current is operating. SOLUTION: A wait control circuit 3 generates a wait clock WC to substantially delay a clock CK for a predetermined time in response to a change of a most significant address CS, that is, to keep the clock CK wait in a wait state for a period corresponding to an operation preparation to a selected memory block, and supplies the wait clock to a CPU 4. The wait control clock signal WC extends the clock by an amount of four clocks intentionally only during a precharge period of a data line. Seen from the CPU 4, therefore, the operation does not stop and no influence is given to a next operation at all. For instance, even if a memory block 2A changes from a non-selection state to a selection state, data of the memory block 2A can be read immediately.

Title: Semiconductor device
Inventor: YUU YOSHITAKA
IPC: H01L23/28
Filed: 1988-07-22
Abstract: PURPOSE:To effectively prevent a case from damaging by extending the cylinder of a cavity from the inner wall of the case from a gel-like resin, and absorbing the expansion force d the resin by the cavity. CONSTITUTION:The cylinder 10 of a cavity is suspended from an upper position from a gel-like resin 5 of the inner wall of a case 4 through a curable resin 6. An opening 10a is formed at the lower end of the cylinder 10, which is disposed in the resin 5. When a semiconductor chip 3 is damaged by a short-circuit accident and the chip 3 is melted, the resin 5 is expanded by carbonizing gas and heat generated thereby. Since the expansion force of the resin 5 at this time is absorbed by the cavity of the cylinder 10, the damage of the case 10 is prevented.

Title: Method for analyzing non-metal impurities in steel
Inventor: SUZUKI KENICHIRO
IPC: H01J37/28
Filed: 1985-08-26
Abstract: PURPOSE:To discriminate the composition and/or form of non-metal impurities and to quantitatively displaying a two-dimensional distribution state, by monitoring the quantity and/or light emitting phenomenon of the electrons reflected from the non-metal impurities exposed to an inspection surface to store the same. CONSTITUTION:The electrons corresponding to the average atomic number to a specimen are reflected from a test piece by scanning the surface to be inspected of the specimen piece by electron beam but, when oxides having an average atomic number smaller than that of steel are present, the number of reflected electrons at the presence points are reduced in the case of steel. Then, the ratio of the number of electrons reflected from non-metal impurities is operated on the basis of the number of electrons reflected from the steel matrix and a threshold value is set to said ratio to discriminate and recognize the oxide system and sulfide system of the non-metal impurities. When oxides are present at the area irradiated with electron beam, a light emitting phenomenon concurs. This phenomenon can be easily traced by the photodiode provided in the vicinity of the electron beam irradiation point and this information is superposed to the threshold value of the ratio of the number of reflected electrons to make it possible to enhance the measuring accuracy of two-dimensional distribution.

Filed: 1980-12-26
Abstract: PURPOSE:To enable high density recording, by increasing a recording signal voltage as high as possible, through making a time passing under a recording electrode as <=10<-5>sec for a recording medium and specifying a recording signal voltage. CONSTITUTION:In the Figure indicating the relation between a recording signal voltage V and a time of each surface point on a recording medium passing  under a recorded electrode, record enabled area beta, recording impossible area alpha,  and discharge destruction area gamma exist.
