Title: Evaluation of metal material for nuclear power plant
Inventor: SUMIYA RIE
IPC: G21C17/003
Filed: 1991-08-14
Abstract: PURPOSE:To estimate and evaluate quantitatively the time of occurrence of a fissure, the speed of development thereof and the behavior of the development and stop. CONSTITUTION:Measurement of radiations of radioactive metal nuclides contained in oxides of a broken surface of a fissure 2 of a metal material 1 which occurs and develops in primary system water of a nuclear power plant and measurement of a metal distribution are conducted. Regarding the metal material 1, in other words, measurement of radioactivity from a change of specific activity with passage of time is conducted. The specific activity changes due to accumulation and damping till a certain time in the water wherein it is to be evaluated. It changes due to damping after the material is taken out of the water. A diagram of the change is prepared, a radiation dose and the metal distribution are measured and the specific activity is determined. From this specific activity, the time tau when the fissure 2 develops to a measuring point can be led out. Besides, the speed of development of the fissure can be led out by dividing a distance between two points on the broken surface of the fissure by the time led from the result of measurement of the aforesaid specific activity.

Title: Image recorder
Inventor: OTSUKA YASUMASA
IPC: G03G21/00
Filed: 1985-09-17
Abstract: PURPOSE:To prevent the white omission of an image and the solidification or melt-fixing of a toner in a developing device by counting the dimming time of a laser beam while correcting it in accordance with a printing rate and integrating and storing the counted value and sending a prescribed signal when stored contents exceeds a preliminarily set reference value. CONSTITUTION:A counter 8 counts the laser dimming time, and a modulator 5 reads out successively printing rates of individual sections from a memory 3 to output a signal which switches the value of one count of the counter 8, and the counted value of the counter 8 is integrated successively and stored in a memory 9. A comparator 10 compares always the value stored in the memory 9; and if the stored value exceeds a preliminarily set level, a signal is sent to a controller 11, and the controller 11 sends a reset signal RST1 to memories 2 and 3 to reset their contents at every time when an image is recorded on one recording paper. When the toner is replenished or a cartridge is replaced, the controller 11 outputs a reset signal RST2 to the memory 9 to reset its contents. Thus, white omission due to lack of the toner and the solidification or melt-fixing of the toner are prevented.

Title: Flash type memory, management device therefor and management method therefor
Inventor: TANAKA KAZUYA
IPC: G06F12/02
Filed: 1998-07-17
Abstract: PROBLEM TO BE SOLVED: To appropriately change the allocation of a program area and a data file area to flexibly cope with a using purpose and to uniformize the write and erasure of respective blocks. SOLUTION: As shown in [A], it is assumed that four blocks are secured from the block (t) as the program area. In this case, management information such as the number of times of the erasure of subordinate blocks t+1, t+2 and t+3 is integrated and stored in the block header of the leading block (t) as shown in [B]. At the time of changing such a program area to plural subdivided program areas or the data file area, the management information stored in the block header of the leading block (t) is referred to. Thus, the block of a change object is selected based on the number of times of the erasure for the respective blocks. Thus, the number of times of the write and erasure of the respective blocks is uniformized.

IPC: G11B19/10
Filed: 1997-07-14
Abstract: PROBLEM TO BE SOLVED: To detect misloading of a disk without obstructing the miniaturizing of a disk reproducing providing an imparting means imparting the force of a disk flat plane direction on a disk being in a loading state loading the disk on a turntable and a means detecting the movement of the disk being in a loaded state. SOLUTION: Since the loading position of a disk D1 is detected by the angle of an arm 40, when a device receives a vibration at the time of transferring the disk, there is a case the disk D1 can not be stopped at a reproducing position correctly. In order to dissolve this problem, a belt 33 is repeatingly forward and backward rotated by controlling a driving mechanism. As a result, the disk D1 receives a force vibrating a little backward and forward and when the disk D1 is in a misloaded state, the disk is made to be correctly loaded on the turntable. Moreover, in order to perform a confirmation, it is confirmed that the disk D1 is not moved by monitoring a pulse signal from an pulse encoder 70 while rotating the belt 33 in clockwise direction for several seconds.

IPC: B23P19/06
Filed: 1989-08-07
Abstract: PURPOSE:To control the presence of a bit with a high accuracy without any influence by the friction and twisting of an absorbing sleeve by detecting and controlling only the force at which the bit presses a screw actually. CONSTITUTION:The force Fb at which a bit 3 presses a screw 91 actually, not the force at which a screwdriver 1 presses, is fed back to a moving command circuit 81.

Filed: 1982-11-19
Abstract: PURPOSE:To eliminate effectively a smear signal by extracting the smear signal in a vertical blanking period of a video signal, storing cyclially it and adding the stored smear signal in opposite phase to the original video signal. CONSTITUTION:A reset pulse is applied to an input terminal 10 in the period of verical scanning, a reset FET 5 is turned on during the pulse period, a sampling pulse of the same period is applied to an input terminal 9, and a sampling gate FET 4 is turned on uring the pulse period. As a result, a signal in the vertical blanking period applied to the input terminal 8 is extracted during this period and the smear signal is stored sequentially onto a 1H delay line 3. The smear signal is stored cyclically in the delay line 3 and transistors (TRs) 6, 7 until the signal is cleared at the next vertical blanking period. This signal is led out in opposite phase from the emitter of the TR 7 and applied to an adder 2. The smear signal is cancelled in the adder 2 and only the video signal eliminated the smear signal is introduced onto the output terminal 12.

Title: Method and apparatus for inspecting coating of glass container
Inventor: FUKUDA TOSHIAKI
IPC: G01N21/90
Filed: 1999-07-19
Abstract: PROBLEM TO BE SOLVED: To inspect the presence or quality of a coating film in a full-automatic manner without relying on visual observation. SOLUTION: A glass container is irradiated with ultraviolet rays from an ultraviolet floodlight projector 1 and the ultraviolet rays transmitted through the glass container are received by an ultraviolet sensor 2 and, when the quantity of the transmitted ultraviolet rays is less than a set value, the coating film of the glass container is judged to be defective. Since the coating film has a property markedly cutting the ultraviolet component of transmitted light, an uncoated container or a container having a defective coating film is reduced in the cutting quantity of ultraviolet rays and can be discriminated from a normal coating container.

IPC: B41J2/28
Filed: 1985-09-17
Abstract: PURPOSE:To provide a printing head of wire dot printer capable of fast printing by forming an iron wire in such a way that its one end is located near a printing wire and the other end toward the fixed end of a lever. CONSTITUTION:An iron core 24 is composed of a square column-shaped main part 25 around which a coil 16 is wound and a tip 26 whose cross section is specially trapezoidal. The upper surface of the tip 26 is opposed to a movable part 23 through a void 15 and the lower end of the main part 25 is fitted into a through hole provided at the bottom of a base 4 and fixed to the bottom by welding. The upper surface of the tip 26 can be arranged as close to printing wire 19 of the movable part 23 as possible almost regardless of the profile size of the coil 16. Consequently the effective opposed area S between the upper surface of the tip 26 and an armature 3 can be minimized and the armature 3 miniaturized. In addition, the center of the rotational motion of the movable part 23 approaches the printing wire 19 and after all, this minimizes the inertial moment of the movable part 23. Thus the movable part 23 can be accelerated almost regardless of the profile size of the coil 16.
