Title: Bit error rate detecting circuit
Inventor: SADAKATA MASAMICHI
IPC: G06F12/16
Filed: 1992-01-13
Abstract: PURPOSE:To prevent the detection of an erroneous error due to a bit shift, in a circuit which detects the bit error of serial data. CONSTITUTION:The first bit of a shift register 1 which holds data to be measured is compared with the first bit of a shift register 2 which holds an expected value by an exclusive OR 5. When they are not matched, the content of the (n-1)th bit from the second bit of the shift register 1 is compared with the content of the (n)th bit from the third bit of the shift register 2 by a comparator 3, and when they are matched, the shift register 2 is excessively shifted by one as the bit shift due to a bit omission. And also, the content of the (n)th bit from the third bit of the shift register 1 is compared with the content of the (n-1)th bit from the second bit of the shift register 2 by a comparator 4, and when they are matched, the shift of the shift register 2 is stopped one time as the generation of an excess bit. Thus, even at the time of the bit shift, the bit error can be exactly detected.

Title: Method and apparatus for black chrome plating
Inventor: MORIMOTO KAZUMITSU
IPC: C25D3/08
Filed: 1980-02-23
Abstract: PURPOSE: To apply black chrome plating efficiently to a large amount of the objects to be plated by pressing the objects to cathode by centrifugal forces and circulating a plating soln. between a plating tank and a cooler on the outside of the tank.  
     CONSTITUTION: Objects to be plated of a small size such as screws are charged through a feed port 41 into a plating tank. When a revolving frame 2 is revolved, the screws are pressed in the outside circumferential direction together with the plating soln. and the screws move upward along the inside surface of cathode 32. Since a constant voltage is being applied between the cathode 32 and anode 33 and between the cathode 32 and auxiliary anode 34, black chrome plating is applied on the screws. Further when the cathode 32 is rotated, the screws roll on the inside surface of the cathode 32 and the screws are black chrome plated uniformly over the entire surface. During this time, the plating soln. circulates between the tank and the cooler on the outside of the tank so that the cooled plating soln. is constantly supplied to inside the tank. Hence, the plating progresses at a nearly constant bath temp. and the beautiful black plating is applied.

IPC: B41J2/14
Filed: 1987-02-02
Abstract: PURPOSE:To prevent the effect of cavitation breakage generated at the time of vanishment of a bubble from exerting on heat generating elements, by a construction wherein a bubble generated through a state change occurring at the position of a heat generating element vanishes at other position. CONSTITUTION:Electric power is intermittently supplied to heat generating element 14 through a switching element to generate Joule heat, which causes rapid film boiling of a recording liquid in contact with the element 14, and a bubble 25 is generated and grows to cause a pressure change, whereby a recording liquid droplet 26 is ejected from an ejecting port 17. The element 14 is curved in a staggered form or a circular form, or the element 14 is surrounded by electrodes 19 in a circular form, whereby stable vanishing of the bubble 25 can be caused at a central position of the form. Namely, steps are formed due to the presence of the electrodes 19, and the high thermal conductivity of the electrodes 19 ensures rapid removal of heat from the bubble 25, so that the planar extension of the bubble 25 is limited by the inner surfaces of the electrodes 19 surrounding the element 14, the planar extension of the bubble is stably set to a circular shape, and the vanishing position of the bubble 25 is stabilized accurately to the center of the form of the element. Therefore, there is no possibility that the vanishing position of the bubble 25 might be deviated to cause damage on the element 14.

IPC: G01N3/10
Filed: 1990-01-31
Abstract: PURPOSE:To enable evaluation of intensity of compression in terms of stress by measuring a particle size of a sample of particulate material and determining a compression intensity from a specified relationship between a compression load and a particle size when a compression displace reaches a specified proportion of the particle size. CONSTITUTION:A CPU 30 determines geometrical average diameter (d) each of a sample 8 of a particulate material and the results of computation are stored into a RAM 31. Then, a compression load (p) (determined as an amount of current supplied to a load device 4) as given when a compression displacement l reaches, for example, one-tens of a particle size (d) reading a compression displacement data is detected with a differential transformer type displacement detector 25 to calculate a compression strength Ss by a formula of Ss = 2.8 p/pid<2>. The compression strength thus obtained can be evaluated as one expressed in terms of stress unit not depending on the particle size of the sample 8. In addition, where a compression load as given when the displacement l increases sharply is measured as collapse load p', a collapse strength Sb expressed in terms of stress unit is calculated by a formula Sb = 2.8 p'/pid<2>. Thus, a comparison of strength is accomplished between samples different in particle size.

Filed: 1986-02-04
Abstract: PURPOSE:To detect the fault of a signal processor with a simple circuit constitution by scanning successively N pieces of signal processors when these processors are actuated in parallel with each other. CONSTITUTION:An address bus 50 must be set at 0 to detect the fault of a signal processor 2. Here the reset signal on a reset signal line 100 is inputted to the processor 2 only. While other signal processors 3-5 are neglected. Now it is supposed that the input signal on a signal line 10 is inputted to the processor 2. Then the selection signal sent onto a selection signal line 30 of a selector 1 is set at an appropriate value and the output signal sent onto a signal line 20 from an external ROM is outputted onto a signal line 40. The types of signals outputted from processors 2-5 can be fixed by simulation in case a specific signal is inputted after the processors 2-5 are reset. This expected value is stored in an external ROM and then compared with the outputs of processors 2-5 to decide whether these processors are working normally or not.

Filed: 1996-01-17
Abstract: PROBLEM TO BE SOLVED: To stably enable the pressure contact and movement of a platen and a thermoplastic head over the entire surface of a medium to be recorded by holding the medium to be recorded to a thermal recording apparatus so as to energize at least one end part of the medium to be recorded in the moving direction of the thermal head and the platen. SOLUTION: In recording operation, the tension received from a sheet member 51 and gauze 31 by a platen holding mechanism and a plate making member 2 is changed corresponding to the positions of both of them. That is, when the platen holding mechanism and the plate making member 2 are present in the vicinity of a fixing member 52, the max. tension is applied but, in this case, the tension of the sheet member 51 becomes the force pulling the elastic member 54 to displace a support member 53 and an elastic member 54. Therefore, the fluctuations of the tension by the movement of the platen holding mechanism and the plate making member 2 are absorbed by the extension and contraction of the elastic member 54 and the gauze and a thermal head 24 are always brought to a pressure contact state by constant force and, as a result, an image can be stably formed.
