Title: Semiconductor substrate
Inventor: KAWAKUBO TAKASHI
IPC: H01L21/822
Filed: 1995-09-13
Abstract: PURPOSE: To obtain a thin film capacitor having a large charge storage capacity and a stereoscopic structure by forming a charge storage capacitance element on the inner surface of a trench formed on the surface of a flattened insulating layer, and sequentially depositing a lower electrode, a high dielectric constant thin film and an upper electrode. CONSTITUTION: Second conductivity type impurity diffused layers 6a, 6b are formed on a region isolated by an interelement isolation oxide film 2 of a first conductivity type semiconductor substrate 1, and a word line 4 is formed on the surface via a gate oxide film 3, thereby forming the transistor of a memory cell. A barrier metal 12, a lower electrode 13, a high dielectric constant thin film 14, and an upper electrode 15 are sequentially formed in the trench formed in a flattened insulating film 9 above the transistor, thereby forming a thin film capacitor. In this case, since the charge storage capacitance and leakage characteristics per unit area generally depend upon the film thickness in the film 14, an optimum film thickness is controlled, thereby obtaining a thin film capacitor having a large charge storage capacitance and a stereoscopic structure and small leakage current.

Title: Hot runner device
Inventor: OONISHI WATARU
IPC: B29C45/78
Filed: 1983-12-13
Abstract: PURPOSE:To precisely detect the temperature of a gate part at all times and consequently ensure the actuation of the gate part in order to reduce rejective product by a structure wherein a temperature sensor is held at the recess of an annular sensor holding part situated on the outer periphery of the gate part. CONSTITUTION:A sensor holding part 8, in the recess 14 provided on the inner side surface of which a temperature sensor 4 is being held, is attached on a gate part 3 and fized by a set screw 7. At this time, because the recess of the sensor holding part 8 is too shallow to accomodate the temperature sensor 4, the temperature sensor 4 is brought into contact under pressure with the gate part 3 in the same state at all times. Consequently, because the temperature sensor 4 senses temperatures in the same condition at all times, the precise temperature detection is possible. Accordingly, the amount and timing of resin injected from the gate part 3 in a mold are surely controlled, resulting in enabling to remarkably reduce rejective product.

Abstract: PURPOSE:To release a drawer by data from external equipment by comparing the data from the external equipment stored in a latch means with drawer release code data stored in a storage means, and outputting a signal to release the closing state of the drawer to an electromagnetic locking mechanism under the condition that both data coincide with each other. CONSTITUTION:The data from a personal computer 51 is inputted to the interface circuit 42 of a cashe drawer 2 via a signal cable 61, and is latched with a latch circuit 43. Meanwhile, on a cashe drawer 2 side, the latch circuit 43 is cleared, and it is judged whether or not an error exists in the personal computer 51. When no error exists, a comparator 46 reads in the data under the condition that the data has been inputted to the latch circuit 43, and compares the data with the drawer releasing code data stored in a memory circuit 45. When both data coincide with each other, a solenoid 27 is excited, thereby, the drawer 2 is released by the function of a spring 13 in a releasing mechanism 11. In such a way, it is possible to release the drawer 2 according to the data from the external equipment.

Title: Method of measuring electric resistance of metallic layer
Inventor: KONRAATO HIIBAA
IPC: G01R27/02
Filed: 1984-11-08
Abstract: A method of measuring the electrical resistance of thin metallic films manufactured under the influence of a plasma. The measurement proceeds by means of a direct current resistance measurement according to the principle of a two point or four point measuring method. The electrical resistance is determined either in the case of at least one measuring or test current, and the voltage connected to the measuring contacts is measured when no measuring or test current is sent through the film, or the electrical resistance is determined in the case of at least two different measuring or test currents of known magnitudes. The measuring methods are applied in the case of manufacture of metallic layers in semiconductor technology, in particular also for the measurement of the ion current injected in the film by the plasma as well as for the determination of variations in the coating rate.

Title: Window signal generating circuit
Inventor: TANAKA SHIGENOBU
IPC: H03K5/00
Filed: 1986-10-06
Abstract: PURPOSE:To greatly take a read margin, and to improve the reliability of a read data by providing a circuit for correcting a window signal in accordance with a phase difference between a data bit read out of a flexible disk cartridge and a window signal. CONSTITUTION:An input signal VI read out of a flexible disk cartridge is brought to a phase comparison with the window signal VW of an output signal of a phase synchronizing part 11, and this window signal VW becomes the signal of a period synchronized with a clock bit contained in the input signal VI. A phase difference detecting circuit 2 detects a phase difference between a data bit contained in the input signal VI and the window signal VW. A correcting circuit 3 corrects the window signal VW from the phase synchronizing circuit 1 by taking a peak shift into consideration by the output signal of the phase difference detecting circuit 2, and outputs a corrected window signal VWC. In such a manner, a read margin to the data bit can be taken greatly and the reliability of a read data can be enhanced.

Title: Real time type garbage collection back-up device
Inventor: HAYASHI KOJI
IPC: G06F9/44
Filed: 1986-10-07
Abstract: PURPOSE:To realize the real time type garbage collection at a high speed and with high object efficiency by simplifying decision of conditions done when a symbol processing program is executed in the form of the load and store instructions to be given to an external register. CONSTITUTION:The head address of a memory area equivalent to the present new space is written to an external register 203. When an entrance argument is needed at the entrance of an incorporated function or predicate, the relevant argument is written to a register 203. Then comparators 204 and 205 work with said argument writing timing. The comparator 205 outputs '1' when the pointer written to an external register 202 is larger than the end address written to the register 203. Therefore the output of an AND circuit 206 is equal to '1' as long as said pointer is kept between the head address and the end address. Then an argument pointer indicates a new space and no interruption is produced to a CPU 310. When the argument pointer indicates an old space, a control circuit 221 applies an interruption to the CPU 310 via an interruption request signal line 333.
