Title: Device for preventing drop of passenger from platform for rolling stock
Inventor: ANDO ROKURO
IPC: B61D17/22
Filed: 1991-12-04
Abstract: PURPOSE:To prevent the damage of an outer vestibule diaphragm even when deviation and rolling occur to a rolling stock by a method wherein a side plate of a flexible material spanning between the tip part of a moving part and the vicinity of the outside of the end surface of the rolling stock and the outer vestibule diaphragm having a spring energized in a direction in which the moving member is always spaced away from the end face are arranged facing the end face of the rolling stock. CONSTITUTION:Outer vestibule diaphragms 6 and 7 are fixed in a protruding manner to the respective end faces of two rolling stocks 4 and 5. The base end part 9a of a moving member 9 is supported to a mounting plate 8 so as to be rotatable around a rotary pin 10, and a tip part 9b is brought into a freely movable state. A side plate 11 formed of a flexible material is formed in a plate-form shape having an area with a given width enough for prevention of the drop of a passenger and a given height. A press spring 13 is located in a compressed state between the base plate 8 and the moving member 9 and always energizes the moving member 9 in an opening state. When a rolling stock passes through a curved truck, the outer vestibule diaphragms 6 and 7 are folded inward against the force of the spring 13 on the side where a distance between the opposite end faces is decreased. When deviation occurs, the outer vestibule diaphragms 6 and 7 are contracted.

Title: Electrothermal transfer recording head
Inventor: SONEHARA HIDEAKI
IPC: B41J2/335
Filed: 1988-12-19
Abstract: PURPOSE:To suppress degradation of print quality and to reduce fusion of resistance layer by coating the surfaces of an electrode substrate and a recording electrode except the end face for supplying power with a conductive material having higher volume resistivity than the resistance layer on an ink film. CONSTITUTION:A recording electrode 2 is formed on an electrode substrate 1 then the tip section 3 of the upper face thereof contacting with an ink film is coated with a conductive material 4 having sufficiently higher volume resistivity than a resistance layer. Since conductive coating agent is employed, discharge is suppressed even if a small gap is formed with respect to the upper face of the electrode section so long as the upper face is contacting with the film, thus suppressing abrasion due to discharge. Since there is no recess to be adhered with fused resistance layer in the faces at the tip of the electrode substrate 1 and the recording electrode 2, the resistance layer does not adhere to the recording head even if power is fed to a portion of the resistance layer on the ink film having quite low resistance and the resistance layer is fused due to abnormal heating.

Filed: 1988-12-21
Abstract: PURPOSE:To freely retrieve and output the corresponding information by cancelling a secret state when a secret holding time passed and therefore cancelling automatically the secret state at a proper time point when such a period of time passed to decide no need to hold the secret state. CONSTITUTION:The desired one of many pieces of information stored in an information memory means 33 is retrieved and outputted and at the same time a secret state is set for the specific information. Thus the retrieval and output of the specific information are inhibited and the secret state is kept. A time information setting means 100 sets the information on the secret holding time which holds the secret state of the corresponding information after the secret information is set. The secret state of the information is cancelled when the secret holding time passed. Thus it is possible to automatically cancel the secret state at a proper time point when such a period of time passed to decide no need to hold the secret state and to easily retrieve and output the corresponding information.

Abstract: PURPOSE: To surely relight a discharge lamp at a high temperature and a high voltage immediately after the lamp is put out by providing a circuit for detecting the discharge lamp lighting condition at an intermediate part of an output terminal of a tube lighting circuit and a high-voltage pulse coil so as to perform the control. CONSTITUTION: When the commercial alternating power source VL is input to power source input terminals 15, 16 of a lag-type discharge lamp lighting circuit, the tube lighting circuit voltage Vs supplied from a lag-type discharge ballast 8 is applied to terminals 17, 18 of a starter 7. Power source is supplied to the control circuit 1 and a switching circuit SW is turned on. High-voltage pulse is induced between secondary side coils 1b, 2b of pulse transformers PT1, PT2, and superimposed on the voltage VL so as to light a discharge lamp L. Lighting of the discharge lamp L is detected by a current transformer CT, and the switching circuit SW is turned off. The control circuit 1 turns off the switching circuit SW even in the case where lighting is not confirmed when a constant time is passed after the input of the predetermined voltage VL supplied from the ballast 8.  Consequently, starting pulse voltage is controlled at a value less than the predetermined value, and the lamp lifetime is prolonged.

Filed: 1992-12-01
Abstract: PURPOSE:To assure required strength and to make weight lighter and cooling efficiency better by forming fins for reinforcing and cooling on the rear surface of the backing plate. CONSTITUTION:A target 1 is supported to the backing plate 2 by adhesion with molten metal. The backing plate 2 is fixed and supported by means of screws 8 to a target holder 4 and is interposed with O-rings 7 for preventing water leakage in such a manner that its cooling water path 22 is covered.

Filed: 1996-12-02
Abstract: PROBLEM TO BE SOLVED: To remove air in a mold and thereby to prevent short molding by reducing the pressure in the mold temporarily at least, in a period wherein a molding material is put in the mold and cured. SOLUTION: A box type molding mold composed of a top force and a bottom tool is heated and a molding compound after maturing is charged in the bottom tool. The top force is lowered and clamping is conducted. The pressure in the die is reduced to remove bobbles, during the time when the compound spreads in the mold, and the clamping is ended at the time point when the compound is filled in the die. In this case, the state of the reduced pressure in the mold is maintained until the clamping is ended. A molding pressure being applied thereafter, compression molding is conducted and thereby a molded article is obtained. Removal of the molded article from the mold is smooth, defective molding is not found and the molded article excellent in gloss and surface smoothness can be produced.
