Title: Production of optical disk substrate
Inventor: FUKIYA KAZUNORI
IPC: B29C45/00
Filed: 1988-10-31
Abstract: PURPOSE:To exactly transfer information pits onto the surface of a substrate and to prevent the generation of errors and drop-out at the time of signal reproduction by blowing clean air at >=10m/sec flow rate from a clean air blowing device provided above the stamper onto the front surface of the stamper. CONSTITUTION:The clean air is blown onto the front surface of the stamper at >=10m/sec flow rate on the stamper surface from the clean air blowing out device 6 provided above the stamper 1. A synthetic resin is then injection molded to produce the optical disk substrate. Deposition of foreign matter, dirt and dust atop the stamper 1 is, therefore, prevented and the optical disk substrate exactly transferred with the information pits formed on the stamper 1 is produced. The generation or the error and drop-out at the time of signal reproduction is prevented in this way.

Title: Waterproof structure of electronic parts
Inventor: AOKI KAZUYUKI
IPC: H01Q1/02
Filed: 1995-10-02
Abstract: PROBLEM TO BE SOLVED: To secure an assured waterproof function in a simple structure by covering the peripheral part of an electronic parts with the water impermeable resin sheets and welding these sheets to make a waterproof seal for the electronic parts. SOLUTION: An antenna module 1 is vertically held between two polyvinyl chloride sheets (water impermeable resin sheets) 30, and both sheets 30 are adhered to each other around the module 1. Then the electrodes for a high frequency welding device are pressed to apply even temperature to the sheets 30 and the high frequency is applied between the electrodes. Thus both sheets 30 are welded to each other at a welding part by the generated heat and the module 1 is packed watertight in a bagged state. Furthermore, the upper and lower sheets 30 are welded to an outer insulation resin coat 21 when both sheets 30 are welded together since the coat 21 of a coaxial cable 20 is also polyvinyl. Thus the module 1 is surely sealed waterproof.

Abstract: PURPOSE:To make it possible to maintain antilock control by providing liquid pressure passages connecting a tandem master cylinder and supply and discharge valves with normally open shut-off valves and connecting the output port of a regulator with the liquid pressure passage connecting the shut-off valve and supply and discharge valve through a check valve. CONSTITUTION:Shut-off valves 67 and 68 work through a control circuit 90 while anti-locking is controlled to shut-off liquid pressure passages 71 and 72, and regulator liquid pressure is supplied from a port 34f to all of supply and discharge valves 61 through 66 to optimumly adjust the liquid pressure in wheel cylinders 51a through 54a.

Title: Digital costas loop circuit
Inventor: YUASA MASATOSHI
IPC: H04L27/227
Filed: 1999-09-29
Abstract: PROBLEM TO BE SOLVED: To start reproduction of a carrier in a short time. SOLUTION: A digital Costas loop circuit 22 includes a frequency error detection circuit 30, which detects a frequency error on the basis of signals I', Q'. In the case that the digital Costas loop circuit 22 cannot detect a synchronizing word signal in spite of phase locking, a synchronization detection circuit 32 detects absence of the synchronizing work signal. When detecting the absence of the synchronizing work signal, the synchronization detection circuit 32 instructs a data output circuit 42 to revise at least either of a sign (+, -) and a multiple (m) of ±m.fs/n data and adds the data to a frequency at which the phase is locked.  Thus, using the frequency at which the phase is locked in this way changes the frequency of the signals, it is not required to conduct again the synchronization operation from the beginning, and the time required for the synchronization is decreased as a result.

IPC: H01L21/205
Filed: 1996-10-21
Abstract: PROBLEM TO BE SOLVED: To provide a thin film forming device with which there is not risk of scattering a toxic or flammable reaction gas into the air. SOLUTION: An MOCVD 14 device is provided with pipes 12A and 12B. It is also provided with a shielding casing 18, which seals and covers a reaction chamber 13 inside.

Abstract: PURPOSE: To improve the durability by forming two ridges with a curved cross section partially projected, and arranging a second ridge under a first ridge. CONSTITUTION: An insert 10 includes an edge surface 13, a rake surface 16A, two ridges 14, 17 and a cutting edge 15. At the time of working with this insert, a relief surface (edge surface) 13 and the first ridge 14 are firstly worn in the width thereof, and width of the ridge 14 is reduced in order. The second ridge 17 working as an additional part of a reinforcing land for the rake surface 16A is going to be worn with a delay from the abrasion of the ridge 14, and at this starting time point, width of the whole of the reinforcing land is suddenly increased so as to avoid breakdown of the insert. Since the additional ridge 17 has the smooth curved surface, chip reinforcing lands are positively engaged with each other at the optimal contact surface thereof per each moment of wearing process of the insert. Lifetime of the insert is thereby prolonged more.
