Title: Optical filter
Inventor: WATANABE KOJIRO
IPC: G02B6/00
Filed: 1985-03-01
Abstract: PURPOSE:To obtain desired characteristics with smaller degrees by using one among the inputs to an N-to-N star coupler as a signal output and one among the outputs as a filter output and feeding each of the remaining outputs through optical fibers of respectively different lengths and an attenuator to the remaining inputs. CONSTITUTION:The light coming in from an input terminal 1 passes through an input fiber 2 and is inputted to a star coupler 3 in the case of 3X3N to N, N=3. The 1st output of the coupler 3 is outputted through the optical fiber to a terminal 5. The 2nd output of the star coupler passes through the optical fiber having the length l and through the attenuator 8 and is inputted to the 2nd input of the coupler 3. The 3rd output of the star coupler passes through the optical fiber 7 having the length 2l and through the attenuator 9 and is inputted to the 3rd input of the coupler 3. The length l of the optical fiber is simply required to be so determined that the propagation time of the light signal coincides with one symbol time. The effect of permitting the realization of the desired characteristics with the less degrees (the number of the attenuators) as compared to the conventional transversal type (non-recursive type) is thus obtd.

Title: Communication control system
Inventor: ISHII KENICHI
IPC: H04W80/02
Filed: 1997-02-25
Abstract: PROBLEM TO BE SOLVED: To reduce the time required for re-connection and to relieve a packet loss in the case that a radio terminal equipment moves between radio sub- networks. SOLUTION: Upon the receipt of a control packet (step 401), a radio terminal equipment reads a sub-network identification code included in a control packet (step 402) and compares the code with a registration identification code (step 404). When the recording identification code is coincident with the sub-network identification code, the radio terminal equipment restores a reception wait mode of the control packet (step 405). In the case that the radio terminal equipment registers no registration identification code and that the recording identification code is different from the sub-network identification code, it is discriminated that the radio terminal equipment moves to other radio sub-network (step 406), the sub-network identification code is newly registered (step 407) and a dummy packet is sent (step 408).

Title: Control unit of fuel injection timing
Inventor: YOSHIZAWA SHIGERU
IPC: F02D1/16
Filed: 1981-03-20
Abstract: PURPOSE:To increase the output and save the consumption of fuel by elevating the control responding speed by providing a back pressure mechanism to the oil pressure shifting valve between the oil pressure actuator controlling a fuel injection pump and the source of oil pressure. CONSTITUTION:Oil pressure actuator 2 controls fuel injection timing in a fuel injection pump 3, changing a relative rotating phase angle between input axle 1a and output axle 1b. An oil pressure shifting valve 4 is provided between the oil pressure actuator 2 and the source of oil pressure 5. The orifice 6 of a back pressure mechanism is arranged in the flowing passage of oil pressure toward a reservoir 5b through a port 4c to a port 4d in the neutral shift position 4B of the oil pressure switching valve 4. Oil pressure from a hydraulic pump 5 is transmitted to a pushing-aside chamber 2b in a short time simultaneously by switching to the switching position 4D because back pressure is kept in the discharge passage of the hydraulic pump 5 in the neutral switching position 4B. Thus the control responding speed can be elevated.

Title: Demolding material frame structure having heat insulating action
Inventor: POORU GURESAA
IPC: E04B2/88
Filed: 1987-02-24
Abstract: The composite laminate is made of two metal parts 1, 2 and a pair of thermal insulating bars of fiber reinforced synthetic material. Each metal part has a longitudinally extending groove which is provided with two rows of transversely disposed teeth which cut into the flanks of anchoring strips on the synthetic bars during pressing in of the strips in the respective grooves. The pressing in of the synthetic material into the teeth of the harder metal parts forms a strong bonded connection which resists the stresses imposed upon the laminate during use. Deformable tabs on the metal parts are used to ensure locking of the synthetic bars in place. The space required for production of the laminate is reduced essentially to the length of the metal parts.
