Title: Optical head
Inventor: OGATA SHIRO
IPC: G02B3/08
Filed: 1989-01-18
Abstract: PURPOSE:To improve the read or write density of an optical head by using a Fresnel lens as an objective lens and detecting a reflected light of high-order diffracted light. CONSTITUTION:An information recording medium 12 is positioned so as to be opposite to an objective lens 10 and a Fresnel lens is used as the objective lens 10. In this case, a primary diffracted light X1, a secondary diffracted light X2, a ternary diffracted light X3 with different focal distance are obtained. Then a recording face of an information recording medium 12 is positioned to the focus of the ternary diffracted light X3 forming a focus to a position closest to the objective lens 10 and the reflected light of the ternary diffracted light X3 is detected by a detector. Since the ternary diffracted light X3 has a large angle theta, an NA (rate of aperture) is increased and a small focus spot is formed to the recording face of the information recording medium 12. Thus, the read density is improved and the information recording medium 12 with a high recording density is used.

Title: Pinion shifting device for starter
Inventor: FUKUSHIMA AKIRA
IPC: F02N11/02
Filed: 1983-01-26
Abstract: PURPOSE:To miniaturize the starter and reduce the weight thereof by a method wherein a rotor is attracted by a stator upon conduction of a motor in the starter for an internal-combustion engine and a pinion shaft is shifted by the rotor. CONSTITUTION:When the stator 14 of the starter motor is conducted, the rotor 15, arranged in a deviated position axially with respect to the stator 14, is moved so as to be aligned with the stator 14. Upon this time, a rotor shaft 11 pushes out the pinion shaft 6 through a ball 8, a pinion 7 is meshed with a ring gear at the side of the engine and the rotation of the rotor shaft 11 is transmitted to the pinion gear 7 through splines 1, 2, planetary gears 21, 3, a clutch outer 4, a roller 4', a twisted spline tube 5 and the pinion shaft 6 to start the engine. When the starting of the engine is finished and the conduction of the stator is cut OFF, the rotor 15 returns by the energizing force of a spring 19. Thus, the provision of an electromagnet becomes unnecessary, therefore, the starter may be miniaturized, the weight thereof may be reduced and the mounting property of the starter to the engine may be improved.

Title: Communication terminal equipment and method for reserving communication channel
Inventor: KIHARA YOICHI
IPC: H04L29/08
Filed: 1995-01-26
Abstract: PURPOSE: To prevent disable communication owing to a busy channel by allowing a terminal equipment desiring to make reservation to designate its own channel number and to send a setup message comprising a reserved channel and an identification code specific to the terminal equipment and allowing other terminal equipment to regard the channel number as a reserved channel number so as to attain arbitration between plural terminal equipments. CONSTITUTION: In order to reserve a B1 channel to avoid the channel from being used by other communication terminal equipments, A communication terminal equipment #1 sends a setup message whose user, user information element is a B channel reservation signal to its own channel number. The message is delivered to communication terminal equipments #1-#3. Each of the terminal equipments #1-#3 compares an identification number to be added with an identification number specific to its own communication terminal equipment because the user, user information element of the received setup message is the B channel reservation signal and updates a channel reservation state list stored in each communication terminal equipment when the identification number is that for other communication terminal equipments.  Since the specific identification number is that for its own communication terminal equipment, the terminal equipment #1 sets 'its own channel' to the channel reservation state list because the specific identification number is that of the terminal equipment #1. Thus, each communication terminal equipment sets the reservation state of B channels in this way.

Title: Chroma signal storage circuit
Inventor: SAWADA AKIRA
IPC: H04N9/80
Filed: 1989-01-19
Abstract: PURPOSE:To save a memory capacity by sectioning an input chroma signal at a period of fSC and outputting the data for one period for the plural number of times when only the data of one period in plural consecutive period is stored in a memory and outputted. CONSTITUTION:A chroma signal inputted from a terminal (a) is sampled by an A/D converter 5 and written in a memory 6. In this case, the sampling and write clock are implemented intermittently and four times of consecutive sampling and four times of pauses are executed alternately. An output from the memory 6 is given intermittently, but during data is outputted, a switch 9 selects a memory output and the switch 9 selects an output of a shift register 10 during the pause period thereby inputting a consecutive sampling data to a D/A converter 8. That is, the same waveform is outputted twice by circulating the waveform subjected to representative sampling by the shift register 10. Thus, the memory capacity is saved.

Abstract: PURPOSE:To detect minute undulations by measuring the thicknesses of the cured matter of liquid form resins having deposited and rmained on the butt faces of core block pieces by making use of interference fringes. CONSTITUTION:A non-adhesive resin 5a such as, e.g., silicone resin or the like, is coated on the SiO2 layers 3a, 3b of a core block piece 1 and the SiO2 layer 4a of a core block piece 2. After both pieces are butted, the assembly is pressure contacted by the use of a bonding jig 6 and the resin is cured by heating for 1 to 2 hours at 60 deg.C. The thicknesses of the cured matter 5b of the resin 5a having deposited and remained on the surfaces of the SiO2 layers 3a, 3b, 4a of the core block pieces 1, 2 are measured by using an inteference microscope 7 or interferometer utilizing interference fringes. If there are fluctuatins in the thicknesses of the cured matter 5b of the resin 5a depositing and remaining at the tentative butt bonding between the SiO2 layers 3a, 3b and 4a, it indicates that there are undulations on the butt faces and therefore the protrusions or the like of the SiO2 layers 3a, 3b, 4a are removed by polishing.
