IPC: A63F9/02
Filed: 1994-07-29
Abstract: PURPOSE:To prevent gun models from colliding with the floor even when they are dropped. CONSTITUTION:Gun models 6a, 6b are connected to a frame 1 by flexible cables 5a, 5b, and players hold the gun models 6a, 6b with hands apart from the frame 1 for games in this gun game machine. The cables 5a, 5b are set relatively short in length so that the gun models 6a, 6b are brought into no contact with the floor even when they are dropped. Since the gun models 6a, 6b do not collide with the floor when they are dropped, no large impact force is generated.

Title: Rotary magnetic head
Inventor: KOOTANI TAKASHI
IPC: G11B15/14
Filed: 1982-11-11
Abstract: PURPOSE:To increase directly the output given from a magnetic head without using a mechanical contact and at the same time to obtain a satisfactory S/N, by providing a magnetic flux generating means at the stator side and an AC generating means and a rectifying/smoothing means at the rotor side respectively and making use of revolutions of the rotor to supply electric power to an amplifier. CONSTITUTION:A rotor 1 has revolutions, and a generating coil 8 crosses periodically the magnetic flux produced from a permanent magnet 5 of a status 2. Thus the AC electromotive power is induced to the coil 8 by the electromagnetic induction. This induced AC electromotive power is supplied to a rectifier 10 to be rectified and then smoothed to DC by a smoothing circuit 11 to be supplied to an amplifier 7. A magnetic head 6 reads the recording signal out of a magnetic tape (not shown in the figure). This output signal is immediately amplified by the amplifier 7 to which the electric power is supplied and extracted to the outside via a rotary transformer. In such a way, the output signal sent from the head 6 is directly amplified by the amplifier 7 on the rotor 1 with no mechanical contact. Thus it is possible to obtain a large output signal containing virtually no noise.

Title: Clamp for wire harness
Inventor: SUZUKI MASAHISA
IPC: H02G3/30
Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To easily align a clamp head with a clamp hole by constituting a band in an elastically expandable and shrinkable state and displacing the erecting position of the clamp head for adjustment by applying an external force to the erecting position in the length direction of a wire harness. SOLUTION: A clamp 1 for wire harness is constituted so that the base section 5 of a clamp 1A to be inserted and clamped can be pushed or pulled in a positional deviation correcting direction by holding the section 5 between fingers when a clamping head 4 is positionally deviated from a clamp hole 15. Therefore, the erecting position of the clamping head 4 can be displaced easily in the correcting direction and the center of the head 4 can be easily adjusted within the range of the stroke S of the head 4, because a band 3 is elastically elongated by the external force. Consequently, the head 4 can be easily and accurately aligned with the clamping hole 15 and the workability of the installing work of a wire harness 10 to a car body or equipment can be improved.

Filed: 1988-08-09
Abstract: PURPOSE:To increase the size accuracy, to realize a uniform quality, and to make the insertion of IC easier, by applying a pressure to the contact member side of an IC lead with a pressing member when a toggle is opened. CONSTITUTION:Before an IC 6 is inserted to a socket 5, the space between a contact member 2 and a pressing member 4 is being opened wider than the thickness of a lead 7 of the IC 6, and no pressure is applied to the lead 7.

Abstract: PURPOSE:To prevent burn-out of a particulate capturing filter, by controlling an engine to supply a relatively large amount of fuel to a fuel chamber when the temperature of the particulate capturing filter is higher than a reference that is higher than the temperature detected when particulates are burnt normally. CONSTITUTION:When it is detected from the deviation of the output signals of pressure sensors 7A, 7B disposed on the opposite sides of a filter 3 for capturing particulates contained in the exhaust gas that the amount of particulates captured by the filter 3 has reached a prescribed value, the filter 3 is regenerated by burning the particulates by raising the temperature of exhaust gas through operation of an injection timing delaying means 31 and a fuel increasing means 25 serving as a filter regenerating means. At the same time, the temperature of the filter 3 is detected by a temperature sensor 40. When the temperature of the filter 3 has exceeded a reference value higher than the temperature detected when the particulates are burnt normally, temperature rise of the filter 3 is inhibited by increasing the fuel supply rate by operating an injection quantity control means 10 in an injection pump 8.

Title: Method for removing metal on pouring tube for tundish
Inventor: NANBA YASUTOSHI
IPC: B22D11/10
Filed: 1990-07-30
Abstract: PURPOSE:To easily remove the metal stuck and grown on a pouring tube for a tundish by merely cooling the pouring tube. CONSTITUTION:On the inner wall of the pouring tube for tundish before using, coating layer having composition of almost 2CaO.SiO2 and 2-10mm thickness is arranged and heated to 500-1000 deg.C. In the case the metal sticks on the inner wall of the pouring tube for tundish after using, by cooling this, 2CaO.SiO2 in the coating layer develops crystal transition of alpha type alpha' type beta type gamma type accompanying the cooling process from high temp. Then, as volume expansion is accompanied at the time of executing the transition from beta type to gammatype, the coating layer arranged on the inner wall of the pouring tube for tundish is naturally collapsed and at the same time, the metal deposited during casting is naturally dropped, too and can be removed. By again setting the coating layer, the pouring tube can be reused.

Title: Disconnection detector of coil
Inventor: YAMAGISHI TOSHIO
IPC: H02P29/00
Filed: 1984-09-22
Abstract: PURPOSE:To readily detect the disconnection of a coil and the shortcircuit by discriminating the output of a comparator for comparing a voltage of a connecting point of the coil with a switching element with a reference voltage immediately after the switching element is interrupted. CONSTITUTION:A processor 100 applies a signal of high level to the base of a transistor 6 during a period W to energize a coil 5. Immediately after the transistor 6 is interrupted, i.e., at a time t2, the voltage of a connecting point 7 of the coil 5 with the transistor 6 becomes a high level by the forward voltage V1 of a diode D from a power source voltage VB. A comparator 10 outputs a signal of low level when the voltage of the point 7 is smaller than the reference level signal from a reference level setter 12. Thus, the disconnection of the coil 5 is detected.
