Title: Abnormality detection circuit for flash memory
Inventor: TOMONO SEIICHI
IPC: G06F11/00
Filed: 1998-02-27
Abstract: PROBLEM TO BE SOLVED: To provide an abnormality detection circuit which can detect the abnormality of data stored in a flash memory even in the case a power source is interrupted during the write. SOLUTION: A sequencer 13 detects commands successively given to a flash memory 3 during write and stores corresponding codes in a storage element 12. When a BUSY signal of the flash memory 3 reports the end of internal processing, the sequencer 13 stores a code indicating the normal end in the storage element 12. The storage element 12 is connected to a backup power source 14 and holds this code group in the period when a system power source 4 is interrupted. If a system 1 is stopped during write, only the code group given till then is stored in the storage element 12. Consequently, the system 1 can surely detect the data abnormality of the flash memory 3 in a short time based on the code group in the storage element 12 in the activation.

Abstract: PURPOSE:To omit a thermal treatment process for removing hydrogen, and to improve mass productivity by irradiating an N-type or P-type amorphous silicon film formed within the specified range of the surface of an amorphous silicon film with a laser and diffusing and crystallizing the N-type or P-type amorphous silicon film. CONSTITUTION:N-type or P-type amorphous silicon films 16 are formed within specified ranges, in which resistance layers are formed, on the surface of an amorphous silicon film 14, and the amorphous silicon films 16 are irradiated with an excimer laser 17, thus forming N-type or P-type polysilicon layers 18 as the resistance layers in the amorphous silicon film 14. The roughened section of a surface is removed by hydrogen (H) contained in the polysilicon layer 18 sections, i.e., the amorphous silicon films 16, remaining on the surface of the amorphous silicon film 14. Consequently, the resistance layers having high reliability are formed without executing heat treatment for removing hydrogen as seen in conventional devices.

Title: Transistor circuit
Inventor: TOJIKI HITOMI
IPC: H03K4/48
Filed: 1978-04-24
Abstract: PURPOSE:To obtain the saw-tooth wave which features a high linearity and large amplitude of the voltage by flowing the cahrge current to the capacitor through the transistor. CONSTITUTION:with application of the pulse signal to input terminal 1, transistor 5 is turned on and off according to the cycle of the pulse signal. When transistor 5 is off, a fixed amount of current is flown to capacitor 8 from transistor 13 to charge capacitor 8. Constant current circuit 16 is the constant current source which sucks up the emitter current of transistor 5 and 14. Thus, the voltage proportional to the time emerges across capacitor 8, and the saw-tooth wave is produced at output terminal 2. The voltage amplitude of the saw-tooth wave is proportional to the collector current of transistor 13. Accordingly, the voltage amplitude of the saw-tooth wave can be varied easily by changing the bias setting of terminal 12.

Abstract: PURPOSE:To attain a highly accurate grinding by a device with the simple constitution by grinding an optical connector core tip, which reciprocatively rotates with a rotating symmetric axis as a center, while said tip is placed against the spherical part of a grind store. CONSTITUTION:While the optical connector core 3 is reciprocatively rotated more than 180 deg. in the partial direction around the rotating symmetric axis M by the rotation of a motor 8, the end face of the core 3 is placed against the spherical surface of the grind stone 1 in the middle of rotation so as to grind it. With this grinding, the ground recessed surface of the core 3 turns out to be a ground recessed surface 10A or 10B, and becomes axis-symmetric with the rotating symmetric axis M as a center. In case of the recessed surface 10A, the verticality with respect to the optical path of the optical fiber end face of the core 3 is guaranteed, while in case of the recessed surface 10B a light beam outputted from the optical fiber end face of the core 3 converges on one point of the axis M to reduce a connection loss. In such a way the device constitution is simplified to grind the core at high accuracy.
