Title: Rotation monitoring method of pulse motor
Inventor: SANO TOMOMI
IPC: H02P8/38
Filed: 1994-07-22
Abstract: PURPOSE:To obtain a rotation monitoring method in which the normality detection of the rotation of a pulse motor is realized by a low-cost means without using a costly rotation detection part. CONSTITUTION:A rotation monitoring method makes use of a situation that the voltage waveform at the end of an exciting coil and the current waveform of the exciting coil are different between the rotation and the nonrotation of a rotor for a pulse motor 3. An amplification part 5a, an amplification part 5b and an analog-to-digital conversion part 6 are provided. The normality of the rotation of the pulse motor is judged by using an operation expression which emphasizes the characteristic of different waveforms.

Title: Punching die
Inventor: ANZAI KATSUNORI
IPC: B21D28/00
Filed: 1999-06-17
Abstract: PROBLEM TO BE SOLVED: To prevent generation of the twist caused by the difference in the lead width of a lead frame material to be punched, and the generation of the twist caused by the abrasion of a punch blade tip by providing a material holding projecting part and a sloping lever to adjust the height of the material holding projecting part on a stripper. SOLUTION: The height of a projecting part is increased when the lead width of a lead frame material 1 is small and the pressure must be increased, and also increased when a blade tip of a punch 3 is worn and its punching resistance is increased. The degree of the increase is appropriately adjusted according to the lead width and the material of the lead frame material 1. When the blade tip of the punch 3 is worn, its punching resistance is increased, and the twist is generated, a sloping lever 7 is adjusted, and the height of the projecting part is increased to eliminate the twist. Even when the blade tip of the punch 3 is worn, the punch can still be used by adjusting the height of the projecting part, and thus, the service life of a punching die can be improved. This means that the maintenance time of the punching die can be shortened.

Filed: 1998-06-18
Abstract: PROBLEM TO BE SOLVED: To provide an instant camera made thin in thickness while being provided with a pressing member for pressing a film unit. SOLUTION: A pressing part 40 is constituted of a projecting block 41, an elongating frame 42, a leaf spring 43 and a holding frame 44. The block 41 is housed in the frame 42 to be freely put in and out, and energized by the spring 43 in a direction where it projects from the inner wall surface of a back cover 35. The frame 42 is housed in the frame 44 so that it can freely get in and out, and pulled out from a hole 44a by the flange 41a of the block 41. The trailing end of the frame 44 is fixed on the back cover 35. The block 41 is displaced between a 1st abutting position P1 where its leading end position is adjusted to the leading end of the frame 44 and a 2nd abutting position P2 where the projection amount of the block 41 and the frame 42 is maximum.  Since the length of the block 41 and the frame 42 becomes nearly the half of displacement length L, the length of the holding part 44 housing them is made much shorter than the length L.

Abstract: PURPOSE:To use a channel with high efficiency and to absorb a traffic fluctuation in terms of a place and time by applying the satellite channel which can control the demand assignment to the inter-station line between an exchange and a base station. CONSTITUTION:If a subscriber 1 dials to a land mobile radiotelephone 28 and there is no connection line from a nearest trunk exchange 5 to a land mobile radiotelephone exchange 9, a line 48 is selected and a selection signal is transmitted to a demand assign control station 33. Said station 33 selects the satellite channel and transmits a satellite incoming call signal to the exchange 9. Said exchange 9 calls the land mobile radiotelephone 28 and instructs the connection of a line 52 to the satellite ground station 44 with a radio channel 24 to a radio base station 20. Said exchange 9 transmits a call instruction signal including identification information on the satellite ground station 44 and that on the line 52 to the control station 33. Said station 33 connects the line 48 to a specific satellite channel which always transmits a ring-back tone. Said exchange 9 transmits the call instruction signal and rings the bell of the land mobile radiotelephone 28. If the exchange 9 receives the subscriber's response, the control station 33 cuts off the satellite channel line 48 and connects the line 52 with a line 56.
