Title: Sand blasting method
Inventor: TSUKAGOSHI KEIJI
IPC: B24C11/00
Filed: 1978-05-26
Abstract: PURPOSE: To obtain smooth, uniform surface finish with higher efficiency and less dirt at pressurized dry injection blasting method by adopting air-crushed slags produced in a Bessemer convertor as a grinding material.  
     CONSTITUTION: Air-curshed convertor slags used for a grinding material are made from slags in a Bessemer convertor produced during steel making process. The slags are spherical with a dismeter ranging from 0.3MM to 2.5MM, and they are blasted to the surface of thick steel plates at a pressure of between 5 and 10kg/cm 2  from nozzles having diameters of 4 to 8 MM which are attached to a pressurized injection sand blasting machine. Thus longer life of the nozzles and more uniform surface finish are obtained with less dirt scattering.

Title: Measuring instrument for thickness of film
Inventor: SUZUKI KOUICHI
IPC: G01B11/00
Filed: 1979-05-23
Abstract: PURPOSE: To continuously measure the thickness of a film without bringing a measuring instrument into contact therewith, by measuring the quantity of light reflected on upper and lower surfaces of the film with photoelectric displacement meters, and applying outputs from the displacement meters to an operator to calculate the thickness of the film on the basis of the difference between the outputs from the displacement meters.  
     CONSTITUTION: The first displacement meter 1 consists of a probe P1 composed of a bundle of optical fibers, a light source L1, a filter F1 adapted to permeate therethrough the light of a wave- length reflected on an absorption region of a film C on a block B, a light-receiving element D1, and an amplifier A1 an output l1 from which corresponds to a distance between the probe P1 and an upper surface of the film C. The second displacement meter 2 also consists of a probe P2, a light source L2, a filter F2 adapted to permeate therethrough the light of a wave-length reflected on a transparent region of the film C, a light-receiving element D2, and an amplifier A2 an output l2 from which corresponds to a distance between the probe P2 and a lower surface of the film C. The thickness of the film is calculated in an operator 3 by using a calibration value on the basis of a difference between the outputs l1, l2. Thus, the thickness of a film can be continuously measured without bringing a measuring instrument into contact therewith.

IPC: H04J3/06
Filed: 1982-04-14
Abstract: PURPOSE:To improve the efficiency of transmission, by superposing an analog signal on the noise margin of a TTL level signal which is turned into a transmitting clock and then transmitting these signals. CONSTITUTION:A sampling circuit 1 samples analog signals 1ch-nch by means of a sampling signal (b) given from a control circuit 4 and applies it to a limiter 2. The limiter 2 gives a control of amplitude to the analog sample signal so as to eliminate an obstacle for transmission of logic 0 and 1. For instance, an analog signal is superposed on a signal of logic 1. In this case, the analog signal receives control of amplitude to be set at 2.0-5.0V. This analog signal, the sampling signal (b) and a frame synchronizing signal (c) are transmitted via a mixing circuit 3. At the receiving side, the signals (b) and (c) which are turned into transmitting clocks through a control circuit 6 are demodulated. Then the signals 1ch-nch are demodulated via a sample holding circuit 5.

Title: Master cylinder
Inventor: NAKANO TOSHIHIRO
IPC: B60T11/16
Filed: 1994-03-31
Abstract: PURPOSE:To improve operating fluid supply speed to a pressure chamber at backward movement time of a piston by arranging a restriction forming means in the middle of a communicating hole so as to form a restriction in the middle of the communicating hole only at forward movement time of the piston. CONSTITUTION:A valve seat 23 is engaged with a tip part of a piston 12 through an O ring 16 while forming a cylindrical inside space 24. A restriction forming member 20 forming a restriction passage in the center is arranged in the inside spece 24. This restriction area forming member 20 forms a sufficient clearance in the circumferential and axial directions. The restriction is made formable in the middle of a communicating hole 18 only at a forward movement time of a piston 12. That is, it is set so that pressing force acts on the piston 12, and it is leftward moved, and capacity in a pressure chamber R2 is reduced, and operating fluid flows in a replenishing chamber R1. Thereby, the restriction forming member 20 relatively moves to the piston 12 side, and comes into contact with the piston 12. Thereby, a communicating passage 18 to communicate between the replenishing chamber Rl and the pressure chamber R2 is throttled, and a restriction effect is generated.

Abstract: PURPOSE:To suppress the height of the whole of a massaging device to a low value without sacrificing the protruding and retracting stroke of a massage head by a method wherein a base bed pushed up through expansion of an air bag is mounted, and a retracting means to protrude and retract the head from and in the base bed is provided. CONSTITUTION:Through expansion of an air cylinder 44 against a bias spring 43 by feeding air fed from an air pump P to an air cylinder 44 side, a massage head 3 is protruded from a base bed 23. Thereafter, with a switching valve KV switched, through expansion of the air bag 22 by feeding air to the air bag 22 side, the head 3 is further protruded to press a body. The periodic protruding and retracting motion of the head 3 during massage is effected in a way to feed and discharge to and from the air bag 22 in a state that the air cylinder is left expanded. During completion of the massage, after air in the air bag 22 is discharged, the switching valve KV is switched to discharge air in the air cylinder 44, and the head 3 is protruded from and retracted in the base bed 23 through energization of the bias spring 43. This constitution enables suppression of the whole height of the massaging device to a low value.

Title: Reproducing circuit for bit rate clock
Inventor: ARAI MASASHI
IPC: H04L7/02
Filed: 1987-03-18
Abstract: PURPOSE:To prevent a phase shift against a reproduced bit rate clock by dividing a pulse which falls after the maximum count value with the polarized point output of input data defined as a rise at a dividing rate of 3 or an even multiple of 3 of the counter output via a divided signal generating means and using the divided signal for a bit rate clock. CONSTITUTION:A pulse generating circuit 13 consists of an OR gate where the 12-output and 36-output of a counter 8 are inputted, an OR gate 15 where the 24-output of the counter 8 and a reset signal are inputted, and a reset/set flip-flop 16 which is successively inverted by an output signal received from the gate 14 or 15 and produces pulses in a 1/3 cycle to the pulse obtained at an output terminal 12. The circuit 13 also corrects a phase shift and the flip-flop 16 is reset first by the initial value '1' of the 36-output of the counter 8 and produces '0' at a Q output. The output signal obtained by giving the 1/3 division to the '1' part of a signal is processed for production of a bit rate clock. Thus a phase inverting phenomenon can be avoided.
