Title: Electromagnetic wave preventing mechanism of game machine
Inventor: IWAI KIYOMI
IPC: A63F7/02
Filed: 1989-04-05
Abstract: PURPOSE:To prevent the generation of a malfunction even if an electromagnetic wave is generated intentionally or by accident by immersing both faces of glass of the front of a panel into a metallic ion solution of tin, etc., or injecting the solution to the glass surface, drying it and burning it, and forming a thin film of tin oxide. CONSTITUTION:Two pieces of glass are fitted into a panel door 5 of the front of a panel 2, and a thin film of tin oxide preventing an electromagnetic wave is stuck to both faces of glass 6 of its inside. In this case, its thin film is stuck to the glass surface by the following method. First of all, the surface of the glass 6 is immersed into a metallic ion solution of tin, or the metallic ion solution of tin is injected to the glass surface, and thereafter, it is dried at 20-80 deg.C. Subsequently, the dried glass surface is burned at 500-600 deg.C, and thereafter, cooled. Next, by repeating these processes two or three times, a thin film of tin oxide consisting of prescribed thickness is formed. In such a way, the glass 6 obtained by sticking the thin film of tin oxide to both the faces to many layers is fitted into the inside of the panel door 5.

Title: Method for setting coefficient of reverberation adding device
IPC: H03H17/02
Filed: 1991-04-18
Abstract: PURPOSE:To easily set a delay time by specifying the delay time of a delay unit which constitutes a parallel-connected comb filter and setting frequencies at which each comb filter generate a reference vibration peak at equal intervals on a logarithmic axis. CONSTITUTION:The reverberation adding device is equipped with (n) parallel connected stages of comb filters; and the delay time of the (k)th delay unit constituting each comb filter is set to Tk=T1/2(k-1)/n and the frequencies at which the respective comb filters generate reference vibration peaks are set at the equal intervals on the logarithmic axis. Consequently, similar uniform intervals are obtained logically and as to octaves, the peaks become hard to overlap with one another, and the intervals make faults due to periodicity hard to appear as to a hearing feeling. Therefore, the frequency characteristics can be flattened by the least number of comb filters and operation for generating a variation of many reverberation sounds is facilitated.

Title: Magnetoresistance effect type head and its manufacture
Inventor: KANAI HITOSHI
IPC: G11B5/39
Filed: 1993-04-14
Abstract: PURPOSE:To suppress the generation of Barkhausen noises without lowering the reproduced outputs by controlling a magnetic domain of an MR element to a degree not to decrease the magnetic permeability of the element in a signal detecting area of the MR element. CONSTITUTION:An antiferromagnetic film 12a bonded at both ends of an MR element 10 is an FeMn film composed of Fe and Mn by 50:50. An antiferromagnetic film bonded in a signal detecting area at the central part, of the element 10 is arm FeMnCr film or arm FeMnNb film, or an FeMnTa film obtained by adding Cr or Nb or Ta to the FeMn film. Since the antiferromagnetic film 12b bonded in the signal detecting area is an FeMn film to which Cr or Nb or Ta is added, the exchange binding magnetic field is rapidly decreased only by adding the element several %. Accordingly, it is possible to generate an exchange banding magnetic field of the size not to decrease the magnetic permeability of the MR element by the addition of a suitable amount of the element. By this, the MR head without the decrease of outputs and restricting Barkhausen noises can be obtained.

Abstract: PURPOSE:To fit a heat-shrinkable tube to a core even in a normal heating furnace without air remaining inside and simply obtain an adaptability even to a continuous process by a method wherein the heat-shrinkable tube is loosely fitted to the core and heated with a temperature gradient in the axial direction of the core to reach the shrinking temperature of the heat-shrinkable tube successively from one end to the other end thereof. CONSTITUTION:A core 10 and a tube 11 are combined with each other using a jig 12 (a heat conduction-retarding body) made of a substance of a slightly low heat conductivity (a corrugated fibreboard), put in a heating furnace in this state, and heated to a shrink initiation temperature (150 deg.C). The heat- shrinkable tube 11 is heated from the top part thereof. Parts 1, 2, 3, 4, 5, 6, are shrunk in this order. An internal air is forced out by going through a process shown by 5, 6, 7. Thus, the tube 11 integrally adheres to the core 10. Alternatively, while the both are heated in a similar manner, the core 10 is gradually pulled out with the shrink of the tube 11 for the reduction of a time by approximately 30min.
